Group A Thread

[nisskid]

you probably need to be more specific, but I suspect jetwreck can just go and check up on any questions by looking in the garage. bastard.

ahk, im basically just interested on what was done to it to get it to the level it was at, so really just everything.

cheers mate.

I always had a feeling that the Group A cars were being underdriven a tad as the owners are not always gun professional drivers + their cars are expensive and often of significant historical value. But...

Wow, Seto jumps behind the wheel and blitzes them So glad to see one of the old Grp A cars turn a bit of genuine speed. I was starting to get concerned by the fact that my lil GTSt can do similar times

[Jetwreck]

Give us a couple of thousand laps around there like Seto and we will get a bit closer. Some of us have only done about 15 laps. I also think that 5 seconds off Seto's pace in the wet is pretty good for non professions.....and bringing them home straight on top of that. Good weekend had by all.

Well done to David Towe(BMW) who won & Bill Cutler(BMW) for third in the last race in the wet.

I was not having a dig at all. The std of driving thru the field is better then i could ever do. Anyway, if i had any one of the cars out there i doubt i would be able to race it becuase of the cars value and the expense to source parts and repair. So massive wraps for both punting the cars in the first place and doing it as well as you all do.

But, there are street cars in the car club that are quicker and it has always left me wondering, has car development come that far in the past 20years? Are semi slicks that much better then the tyres that were run 20years ago. Or does the old power vs weight with good grip will bag you better time? So for me it was good to see the M3 show the turn of speed it did

Any truth to the talk late last year that Richo, Seton and Bowe could be regulars this season? Be great to see, and i imagine as a competitor awesome to be racing against drivers of that calibre

[Jetwreck]

I just re-read my response.....sorry my response reads a little different to how I had it in my head.....I know what you were saying and it's pretty clear you weren't having a shot at us.

There are some pretty quick street cars out there I agree.....but can they do 1,000k's at 9/10's or even 40 laps at Eastern Creek at that. On top of that do they get better the longer they go? I have driven some pretty well prepaired street registered race cars in the past and non of them really do the race thing as well as the Group A's or a purpose build race car. Power to weight with good balance and grip should always pay off. I find if you have to much power it is very easy to overdrive the car, or make tyres go off. This is OK for short races or sprints but not for long races. Just to be clear I am talking about Circuit cars not Targa/Hillclimb/Sprint cars.

Richo is still racing his Falcon, Bowe his Mustang and Seton his Capri. What I can tell you is Seton may be driving MCM this year with us. Wether it's a BMW or Sierra I don't know. Unfortunately I wont be racing at MCM but Dad will.

P.S. Payback will be sweet if it rains at MCM....I'll see how Dad likes semi slicks it the rain!!!!

No unfortunately. Finding contemporary hi-res pics of the cars is really diificult.

[Motorhead]

they're not the highest res images, and i'm pretty sure i got them either from the photography section here or over at r31skylineclub but hope these help, have a better res collection of Group A R31's

or

thanks mate.

I just wanted something better than the pissy little one i found.

If i ever get to the stage where i have more money than sense, i would love to build a complete replica in that colour scheme.

Hehe - I have same vague plans for a track R31 in Group A guise. This PDF scan may help for a 32 replica.

From memory powerplay imports have the GIO R32 for sale... POA of course
