Gareth runs the RDA's on his GT-R for track work, and says they're holding up fine so I'm sure they'll be enough for your street application.

The Stoptechs are pricey, I wouldn't bother with that expenditure for the street personally.

Just got up at 4 and did a dawn raid on Authur's Seat and the surrounding hills. Great fun. 17" were fine, though they definitely tramline more than the 16 x 8s....but I reckon they look super cool so I'll have to put up with that for now, plus bigger brake will fit. The Tyres I inherited were truely terrible, though I am comparing them to some R specs I was running on the 16s so perhaps an unfair comparison.

I've contacted Stuckey and they're highly recommending Dunlop Supersport Race in 245/40 17. Apparently they're very quiet, very good in the wet and only slightly slower (half second) in the dry around a track, which I don't care about. They're also cheap (relatively.....) at $395.

Problem is the aspect ration is 40 which means they will be about 25mm less in diameter which will mean the car will sit lower and the rim won't fill the guards at the top unless I lower it (which I'm not sure if I can do with the coilovers I inherited), but overall I'm dropping it 25mm if I can.....

I've seen very small dimensional changes in rims and tyres make a big difference to a car's stance, so I'm a little worries about going down this road.

Any thoughts? Are there better alternatives than the R Dunlops (Bridgestone?), perhaps with better sizes?

25mm in diameter is only 12.5mm in radius, so your car will only sit 12mm lower, which to me is whether you had a big dinenr or not :)

Agreed, but you then have an extra 12mm between the guard and the top of the tyre which will potentially look, erm, gay. So you have to lower the car 12mm, thus 24/5mm overall and the whole lowering the suspension issue.....

I've found some RE55s in 235/45 which give a 9mm diameter difference which should be OK but they don't come in until August (they reckon).

Anyone recommend where to buy these units most cost effectively in Melbourne or there abouts?

Still unsure of which way to go brake wise. I'll give you a call in the next couple of days........

Hi LotusGTR,

Before upgrading anything on you brake systerm, you can try to order a set of Brake Master Cylinder Stopper for your R32. The brake cylinder stopper can reduce the movement of brake master cylinder when everytime you apply the brake padel. As a result, full brake power can be transmitted to the calipers no brake power will be lost.

Hope this information helps.... :(

Some people notice a big improvement from pedal effort, others less. I think it has to do with the condition of firewall etc etc. But is a nice to have that compliments the other brakign components.

But as a stand alone modification, it will do very little to help the braking capacity of an underbraked GTR :) But is $150 odd well spent all the same

I really like the brake setup i have on my gtr,

i have f50's on the front with project mu pads, i think some crazy high level 900's (silly purchace) but before i had the project mu's the pads that came with the car were quiet nice for track work and spirited driving.

on the rear i have rda standard size rotors with project mu 500's the balance seems pretty good.

i've not checked what brake master i have but i think its standard 32, and there is a cusco stopper on it,

Ive got the RDAs all round and theyre great. Slotted and dimpled. At sandown they were fine while being STOMPED on coming up to turn one...no good vibrations after, i just need some new pads cos bendix are shite.

Sorry to hijack but are the camber-rod-deflectors very helpful? Ive chopped the backing plates too. (info could be helpful to you Lotus) Will aluminium plates do the same as the plastic ones? Anyone have pics of them?

Hey mate, try Protek Tyres or Bridgestone Maribyrnong for the RE55's. They may have some in stock.

Femno: Attached is some pics mate. I can't comment on them because I don't have them, but am looking to put some on in the near future.

Thanks Phunky. What are these called? Where'dya get em from? Look simple and possibly effective.

Does anyone know if cutting off (they don't unbolt?) the dust shields / guards will give any dramas re roadworthiness? I'm too old for dramas with the cops and re-instating things that got 'cut off' when it comes to selling it on (in the distant future I hope)

Also, I guess Nissan put them there for a reason, so what are the downsides of cutting them off?

Thanks everyone.

Femno, you running standard calipers and 296mm rotors? Anything else you've done other than the rotors?

i've just ordered a set of tyres from the US...

I'm sick of being fleeced by the Aussie retailers (who in defence are being fleeced by the distributors).

I've ordered a set of Michelin Pilot Sport PS2s in 255/35/18

4 for a total of ~1500 US$. Now even with duty and customs ~20%, call it $2000 aussie dollars.

The quote I've gotten from a few retailers here are between $750-900 per tyre!

They're made in france, then sent to either the US or AUS. How is there such a big difference???

reason for my rant, LotusGTR, you may want to check out the semis that you can get out of the states - eg yokohama A048 from the place I odered:

www.tirerack.com

Chairman, I've got mates who buy stuff from the States for their Mustangs and they say the FTA means no duty, or is that under a certain value?

Thanks for the tip. I'll check it out.

They're just called air deflector plates from what I'm aware, you can get them from nismo.com.au under the brakes section.

Sorry, I can't help with the legality issue of the backing plates, I have no idea!

Marcus: Good link mate, pity they don't sell RE55s in the states, or DZ03g's :(

I think it's under $1K AUD that is duty free.

ps I'm Marcus :(

Dane, yeah this tyre retailer doens't sell RE55s but I'm sure you can get them.

You could always go Michelin Pilot Sport Cups :)

A mate of mine bought in some very large 17' tyres (300+ bag width FFS) from tire rack in the states for his Daytona coupe. The FTA means no import duty (F=free) & the price was so cheap as to be laughable.

As for the air deflectors from Uniques - last time I enquired they were not available for R32 GT-R's. Hopefully that has changed.

    • No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️
    • Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney
    • I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"  
    • Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all! Link to the freely available model on Printables: Click here Regards, Sean  
    • Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.
