New JDM racing category

A new circuit racing category for cars produced for the Japanese Domestic market (JDM), is set to have its first run at Queensland Raceway on March 24th and 25th. The category will be run as part of round 1 of the new QR Championships and will include two classes to run simultaneously over both days. The two classes will include an “Elite” class which will be more along the lines of an improved production class and a “Club” class which will be more open to modifications. Although both classes will be run together, there will be two separate championships with points allocated for each class.

It is envisaged that each race meeting will consist of two practice/qualifying sessions and four races over the two days. Currently the QR Championships are to be held over four race meetings throughout 2007 and with the possibility of Lakeside Raceway becoming available later in the year, there is a chance this circuit could be included in the 2008 championship. The organisers have also expressed interest in taking the class to a national level, with the inclusion of some interstate tracks and its own national championship.

Listed below are some of the basic regulations for both classes. Please keep in mind that these are still open to change at this stage as the classes are fine tuned to suit competitors.

ELITE CLASS

This class will be for any mass produced car for the Japanese Domestic Market. The idea being these cars will retain the looks and basic engine and driveline configuration of the base vehicle.

Bodywork – Original, as per manufacturers specs.

Engine – Original block and heads. Increases in capacity are acceptable. Engine internals are free. Bolt on mods are free.

Transmission – Original gearbox casing. Aftermarket gear sets etc are acceptable. Remaining driveline components are free.

Wheels – Free, providing they fit inside the original guards.

Tyres – Road legal "R" spec tyres.

Brakes – Free

Suspension – Free

Fuel – Commercially available pump fuel

CLUB CLASS

This class will be for any chassis/bodyshell from a car produced for the Japanese Domestic Market. It will allow for more modifications in bodywork, engines and transmissions.

Bodywork – Chassis and bodyshell to remain as per manufactures specs. Essentially the rest is free at this stage but other items such as front and rear spoilers, replacement doors and guards etc will be fine tuned at a later date.

Engine – Any engine from a JDM car

Transmission – Any transmission from a JDM car

Wheels – Free

Tyres – Free

Brakes – Free

Suspension – Free

Fuel – Unleaded

There have also been discussions in relation to having more classes, including naturally aspirated etc and these will depend on whether we can get enough competitors to run a separate class. With the category currently in it’s infancy we are happy to take feedback from interested parties to help mould it into shape. If you are interested in any further details please contact Cameron Wilson on 0419768662 or myself via a reply here and we look forward to your support at the track for our first outing.

Regards,

Paul Chapman.

please don't take this the wrong way, but the lack of regulations is going to make this a cheque book racers wet dream. anyone without massive dough is going to get caned. great idea though, and I hope it evolves and get's good support.

JAGR33,

If we get the support for a national series we will be racing at Winton, another AASA track, but at this stage I'm not sure whether Victoria is looking to make it part of their AASA Victorian State Championship. This event is an AASA event and as such recognizes both, CAMS NC (old C3) Licences and AASA licences.

Beer Baron,

The regulations are reasonably free at this stage because we are trying to attract as many people as possible to get it up an running. As stated in my first post we will be looking to "fine tune" the regs to make it appealing to as many as possible. This might mean a stricter "Elite" class for more standard production type vehicles if we get the numbers and we have already discussed things like Elite NA and Club NA categories, once again if we get the numbers and support.

While I have a few minutes to spare I thought I'd elaborate a bit on this category and the requirements to run.

Vehicles:

Apart from the basic regs above there are just a few safety items that you'll need to compete. A minimum of a bolt in 4 point cage is required but I highly recommend if you are considering this sort of thing you have a 6 point full cage. You'll need a battery isolator switch which is easily hooked up to switch power off to the car should the need arise. You'll also need a minimum of a 4 point harness but once again I'd recommend a 5 point harness. Apart from that just the usual fire extinguisher, battery triangle, secondary bonnet latch etc and you're set to go.

Licensing:

This category will be run under as an ASSA event which means you'll need a National AASA licence or a CAMS PC or NC licence. If you alrady have an AASA Clubman licence, and have competed in 5 or more sprints, you can just upgrade to the National licence buy paying $145. If you haven't either licence then you can be observed during a practice session and if the officials are satisfied you can pay $200 for the National licence.

Cost:

The entry fee for one of the QR Championships is currently $149 for entries received before the Wednesday prior to the event or $199 after that.

Cheers Paul.

great to see this getting off the ground....CAMS have been super anti-jap cars with their regs until now. I share Richard's concerns about the cash some competitors will spend with such open regs (hell I can only just afford 3E racing). But I totally see your point about opening it to as many cars as possible.

Are these regs aligned with the SuperTT regs that AMRS are running? I am trying to get a copy of they rules, I think our second car would make a pretty good impact on that category. Will try and bring it up for a thrash with you guys under these regs once it is running too :no:

haha did anyone get any new emails about cams updates with sport sedans in their state championship round now....they are opening it up to japanese cars and freeing up some of the rules on turbos and whatnot...guess they are losing people and trying to regain some form of popularity...one min they piss us off and then they come back groveling for support...even offering cash prizes now too!

Cams is so sad...typical old boys club...dont like new cars and dont like anything with a hair dryer on it.

Yes i noticed this, my brother is thinking of running in sports sedans rather than marque sports once his rebuild is finished. I think its great that they are moving with the times. I love the chev powered escorts and alike and it will be great to see skylines, Z's etc out on the track, maybe some people with deep pockets will build up some super GT styled cars to run. I do know that if your car is turbo charged you cannot space frame it.

seroius! I hope it comes to victoria, do you know which series it would be with, VSCRS or VMRC? How difficult has it been to get this new series up and running? i could see this running in another class like 944 ran with marque sports until thier field grew and they got thier own race. At the last VMRC round the saloon cars and sports cars ran together and the field was still small, so JDM could run with them to begin with. Anyway just thoughts, it sounds very exciting esp to someone about to start building a new track car. Would my brothers 240Z with a RB25 be elligalble?post-35252-1172956072.jpg

Myself and someone i know are tossing around the idea of building up a track car - more than likely a '32 GTS-t - as yet, we are undecided as to what category/series/class that we want to aim for...

i heard about this new JDM Category through whispers on the grapevine, just wondering what sort of 'parity' there is?

i.e. does it use the same parity regulations as Improved production/cams events for turbocharged cars?

The rules are quite flexible at this stage but I'd say that the Elite class regs might be reined in a bit too try and keep some sort of cost cap on the category, once we have the numbers. The Super TT rules are also very liberal ans most JDM cars would be eligble for either category. Would be great to see a few interstate competitors and I hope we can get enough support to run an event at Wakefield sometine soon.

I hope so to. I don't really follow the Victorian state scene much but being a AASA series it would have to be run under the same licence down there.

Yes your brothers 240Z with a RB25 engine would be eligble for the Club class.

The improved production regs state that competitors with turbo charged vehicles must run a 34mm restrictor to limit power. This has been imposed to make sure much older existing cars in this category remain competitive. This has been a major stumbling block for most competitors that want to run late model turbo cars and has led to CAMS trying to oversome this back lash by bringing in new regs for Sports Sedans to allow turbo charged awd cars. This might be an alternative for some but we believe that this is a category that will really strike a cord with a lot of people with hi performance jap cars that want to take the next step after supersprints etc.

At this stage there are no restrictions to bolt on mods but once again we'll be open to feedback from existing and potential competitors.

Paul.

i was talking more in terms of a turbocharged engine has a 'capacity' multiplier....

i.e. a RB20DET is a 2L turbo, but then you enter the multiplier into the equation, and you're then in the 4+L category - what sort of categories will the JDM Series have, as obviously it's not going to be competetive running an RB20DET in the same category as something with an RB25DET or a RB26DET

azzurra at the moment there isnt any real similar regs for the aasa stuff at qr.. Its not as strict as cams stuff. That may change as said previously in the future as its grows. The good thing about the aasa stuff is its more enthusiastic about japanese and turbocharged cars...where one day cams is all pro new stuff...then the old boys start losing so the next day they have a big cry and change the rules/regs...but then they lose the numbers and need to rechange it all cause old people die off...so it only leaves us new generation to continue it all. They gotta face the music at somestage.

But yeh..if you run your rb20 then you will probably be up against 25, 26s and even 30dets and obviously other cars with similiar engine capacities.

AzzurrA,

R33 racer is right, at this stage we don't have any sort of engine capacity limits in place, just the engine block regulations. There has been talk of introducing engine capacity classes if we get the numbers and support.

All in all though you'll find that the AASA events are a much more relaxed affair and generally speaking cheaper to compete in. It's all about just having a category to run your car in regardless of what mods you have done to it. At the end of the day though, as in any motor sport, if you want to win races you'll need to spend the money however at least you have the chance to compete at any level and just have fun.

Paul.

I hear what ppl are saying about the rules being too free, but you need to see ppl out there.

So rather then try and limit access to some cars that may be already built as uber quick road cars...best thing to do is intruduce ballast.

Ppl will hat the idea, but over the course of a race ballast will sure help the more std cars catch / keep up with the cars with more power, tyre and suspension as it all struggles with the extra 60kgs etc.

Good wok, if i could afford to bend my car it seems like fun. My only other comment is you shoudl be able to use the same family of engines. So the RB20 guys can use the RB30. The MX5 guys can use the later model bigger cc motors. Early RX7s can use 13B/20B etc.

They can, they will just have to run in the Club class. :(

    • Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in
    • Let's just fix the problem by f**king the rest of the gearbox.
    • Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
    • How much does the shifter move when the car is in gear with the engine off? If it is more than about 1cm you need to replace your shifter bush. Your shifts will just get crunchier, not faster, with a short shifter unless you also rebuild the whole box
