ah noooooooew.

We ran out of fuel!!! Ended up with a 1.04.9. Had a low 1.04 in it, but wasn't to be.

Huge challenge even to make the event. The old man and my brother put in a big effort.

In the weekends leading up to it we dropped a heap of weight, did heaps of maintenance to suspension bits, changed the diff (mine is broken, no time to fix), borrowing brake pads on Monday night (i was working in sydney tues-fri) and in the days before get a wheel alignment and new tyres (on Friday).

At a track I'd been too once before, with tyres I'd never run before (z222 285/35), with no ABS (borrowed diff was a non ABS unit) we ended up 4th in Club, so very close to 3rd.

Great result and congrats buddy especially with all the challenges . What's your car weighing in at now?

Was 1350 with half a tank and no driver on the PI scales. We have taken 80kg out of it.

Those 285's worked well, well done

Thanks guys. Now the work begins to get more performance out of the car.

There is a WTAC rule revision in the wind as well, so wait out for that before proceeding.

[stevena]

What have you heard?

[fatz]

changing the rules just before teh envent

how to make customers happy!

[PMRED32]

I heard one of the top Pro Class cars (and its not Memo) cant comply with the new rules, so they need to do an amendment for them to ensure they can compete.

[ssxRicho]

New rega are up.

[levinboy]

I don't like the new changes

[PN-Mad]

What has changed? I read through, and bar the table of weights from last time I checked, I couldn't find changes.

But I just skim, as not a competor.

[levinboy]

"Alternative materials are permitted for the Front Bar, Bonnet, Side Skirts, Rear Bar and Boot provided they follow the same shape as the original part.

Alternative materials are permitted for front and rear flares.

Localised modifications of OEM fenders to allow fitment of the control tyre.

OEM fenders must be of original material however flare extensions are permitted to cover control tyre.

The top 1/3 of the tyre must not protrude outside the guard/flare when the wheels are facing forwards.

The remainder of the vehicle body must remain as original from the manufacturer. (no wide body kits)"

Bolt on flares

[PMRED32]

In Pro class they changed the following for chassis

5. Rear retention of the original chassis:

6. Original floor pan and frame rails must be retained from the firewall to the forward most point of the rear wheel arch. Allowance for removal material for fitment of fuel or fluid tanks and associated fittings is permitted

So you have to retain the floor plan and rails except you don't....... I heard that this one was coming as one of the top Australian Teams that was on the podium last year had actually had cut the entire middle of the car out for the fuel cell and oil tanks.

[stevena]

Short notice, is this affecting you guys at all? I need to re read them again... Especially with the new interpretations.

Alternative materials are permitted however all bodies must follow the same shape and retain the original look and style of the vehicle. Does following the same shape mean keeping the original side skirts? Keeping the original front bar?

Front and rear bars may be modified to incorporate aero design. Front bar may not extend further than 150mm forward and rear bar no further than 100mm rearward than the vehicles bodywork. Interesting

[fatz]

I predict all the protests will be the best part of this event

[stevena]

So had a chance to read through the new rules and it doesn't affect us in open class I don't think, it actually cleared up a couple things that needed clarifying. Glad they posted all vehicle weights, those evo's are so light to begin with.

[9krpm]

Yes those early Evo were very light.

I think they quoted the wrong minimum weight for the R32 GTR. Nissan produced a number of N1 car with a curb weight of around 1400kg. Let me try to dig out some more info

Ahhh Wikipedia it is http://en.wikipedia.org/wiki/Nissan_Skyline_GT-R:

The Skyline GT-R 'N1' model, introduced on July 19, 1991, was designed for home-market N1 racing with a total of 228 units produced. The most notable change was in the engine, which was upgraded to the R32-N1 specification. The car was also lightened by the removal of the ABS, air conditioning, sound system, rear wiper, trunk carpet, and the use of light-weight headlights. No color options were available and all 'N1' cars were delivered with a thin layer of Crystal White paint. The result was a 30 kg weight savings for a curb weight of 1,400 kg.

Hey dan, this is correct but in the new rules state that the car must have been produced at least 500 units to comply, what do you think your car will weigh?

That's the one.

I'm extremely disappointed, but at the same understand why they have had to do it. If the vast majority of the field enter with cars that are not compliant to the rules, then the class either folds or the rules change to allow those cars to run.

It's stuffed me around to the tune of $3k in wheels (as I wanted to run 10.5 + 15 but wouldn't fit under the guards so bought wheels that could and in doing so decreased the chance of getting a 295 on there), if I was an Evo driver I'd probably have more of a say.

Basically to stay competitive I need to modify the guards now.

It's funny how the magical "500" number pop up. If it's good enough for the Japanese to accept the N1 for racing why isn't it good enough for time attack event

I suspect those Evo weight are not quite the mass produced version either. I suspect some bias here.

We will make it as low as possible and then add weight if we are under. Only WTAC requires minimum weight, the other events don't so I don't just build the car for that weight. It's not easy to get the GTR to below that any how but just in case. Not nice to see some unfairness of this magical 500 number. Does anyone know of any real reason for the "500"?
