trackcar

[wilson]

Hi all,i'm new to the forum but not to vauxhalls.Anyway i have bought back my '84 astra gte to use on the road but its main use is going to be thrashing around castle coombe.So far i have completely stripped the interior apart from the dash and headling,removed some of the wiring and fitted a k&n induction kit!It already has a full stainless stell exhaust and uprated manifold, lowered and 15" tsw alloys.

Re: trackcar

LOL agree totally especially if it's the standard 8V brakes! Don't forget the suspension as well. Avo is good and reasonably priced.

Oh yeah and hi, where are you in Wilts?

Re: trackcar

Don't even think about anything less than 16V ATE type calipers. Really you want 284mm setup off a Cav/Cally Turbo as it means you can keep same master cylinder for same pedal feel, or fit 288mm setup off Cav/Cally V6. People seem to fit the 288 without changing the m/c but I wouldn't be happy with the standard m/c.

I'm in Warminster.

ATE type 16v one are deffinatly to small for the astra on any track, especially a fast one like coombe.

The 284mm Cavalier/Cally turbo and V6 one as richie says is a common setup and pretty good.

The 288mm setup is only found on Vectras (not cav/cally) though and thats the one I used to very good effect. The reason I used it is because the piston in the calliper is larger then the 284 setup, and the parts are a fair bit newer than even the youngest 284mm parts.

Ive now gone to the Astra mk4 GSi/Vectra GSi 308 mm setup, thats massive!

Richie - I understand the theory behing not using the 288 steup, and I have to be honest I never noticed any problems with the 288mm brakes and never noticed any difference in pedal feel. Any more modern m/c would be an ABS compatible one and not suited to either an 84 astra (wilsons) and 88 astra (mine) as both dont have it.

which M/C would you use? If I could find a larger one I'd use it with out a secont thought! Pre ABS Carlton/Senator might be compatible, but maybe not larger!

Re: trackcar

Re: trackcar

308 callipers though? I hadnt really considered it after not having problems with the 288 setup.

308 mm calipers are 288's with different rear brackets

Re: trackcar

is that all? cool so no more additional problems. Cheers for that info rob.

I can confirm that the GTE M/C is up to the 288/308mmmm job then
