Mate...

I'm in need of some slicks for my R33 GTS-t...

I read in Zoom that you ran 15x8.5" slicks on the back of your car? Did you fit those over the standard rear brakes? If so, could you please hook me up with some details on where I can get some of those "Convo Pro" rims?

Cheers mate,

Andrew.

Thanks heaps Brett!

A few more questions.

I'm deciding whether to use 26.0/8.5-15 or 28.0/9.0-15 MT ET Drags...

I have a manual gearbox, so I guess I'm going to try and minimize the shock on my drivetrain as much as possible... Would the larger diameter 28s be a lot harder to spin up, and hence place a larger shock on my gearset?

I'm assuming that it's easier to spin a smaller diameter tyre than it is a larger one? I'd love the softer sidewall of the 28s, but the increased drivetrain shock may not be worth it?

Secondly, I've decided to go with the Cragar Drag Star II /Weld Pro Star style rim... There are a few different options available, but I'm not sure how they translate into offsets and stuff...

Which one would be suitable for the rear of the GTS-t?

15 in. x 8 in. (5 x 4-1/2 in. B.C), 3-1/2 in. RS

15 in. x 8 in. (5 x 4-1/2 in. B.C), 43-1/2 in. RS

15 in. x 8 in. (5 x 4-3/4 in. B.C), 3-1/2 in. RS

15 in. x 8 in. (5 x 4-3/4 in. B.C), 4-1/2 in. RS

15 in. x 8 in. (5 x 4-3/4 in. B.C), 5-1/2 in. RS

Thanks again mate :mad:

Hi merli firstly you will not fit the 28s because they will expand too much and hit the guards and you won't fit the 26x10s unless you fit solid bars instead of suspension as it was our first run with the 26x10s cought the side skirts and ripped them off and put a big dent in the tyres so i suggest the 26x8.5s i have run a handfull of 9sec passes at over 140mph on that size with a standard diff, drive & tail shaft as for the gearbox i cant help you there other than it's cheaper to replace a cluch than a gearbox so just flair the cluch a bit, as for the wheels i dont know off hand what the offset is but i do remember it was the most furtherists offset out that centre line do on the convos ring shane if you get stuck, hope this is of help.

Excellent... I guess I'll go ahead and order 26x8.5-15s then!

You ran your passes on standard diff, driveshafts and tailshafts?!? I've already broken one driveshaft on my first outing! And that was just on 18" Dunlop Formula Rs! I was expecting to snap a whole bucketload when I put slicks on... Hmmm... I guess it's good news to hear yours have held up, hopefully the new one will suffice...

I'll give Shane a call and see if he can shed some light on those weird Imperial measurements for me :mad:

Thanks for all your help mate!

Andrew.

    • My OCD says that exhaust is sticking way to far out for a BMW.   Sorry for making you now upset with your exhaust again...
    • That is not true. The R32 GTR wiring diagram is freely available and has been for literally 25 years. And you don't even actually need it because the situation is so simple that you literally only have to use the wire that runs to the original dash indicator. Your car has a problem. That problem is unique to your car. I assure you that if I went out and did it to my car right now, it would work.
    • Thanks man, yes unfortunately normal bar went on after a minor accident. Smash repairer ordered the wrong version, needed my daily driver back asap so just accepted it.  Hoping an aero bar in gun metal grey (KH2?) pops up for sale soon, I know paint from different cars won't match perfectly but will look good enough
    • If it is the case that your stock dash high beam light lights up as it should, all you have to do is tap into the power wire for the high beams dash globe and feed it to pin 25 on the Haltech dash. 
    • I thought you said the stock dash high beams light doesn't light up when you push the stalk forwards and lock the high beams on?
