Gtr Suspension/tyres

[donkey]

hey there, 380rwkw r33, standard suspension, 18x255x30 toyo proxes tyres, i would like to keep my car standard looking, maybe just lower it 1 inch all round though, will this effect rear traction when drag racing? are 30 series tyres a bit low profile for drag racing? if so what profile would be better? should i get some standard 17x255 for the track?

cheers robbie

the best suspension for drag racing is stock suspension... unless ofcourse you wanna go r.i.p.s styles.

but for the average joe skyline owner stock suspension nice n spongy,

tyres the more wall the better...

why you might ask, running 16, s 225 50's deflat them to 16 psi...then shove some 18's on your ca and see how your launch goes.... compare them, then you will understand why a 15 ich drag slick will get more grip than your bling bling 18 inch enkie light wieght circut rims

will lowering the car ride hight by 1 inch have a big affect on rear traction for drag racing? or his it mainly the firmness of the shocks?

cheers

Lowering will increase your static camber (which you can fix), but your dynamic camber will also increase which isn't easy to fix. What this means is, as the car squats, you gain heaps of camber and throw away grip.

Also, just going by theory, I would think for a 4wd, you'd want as little weight transfer rearwards as possible, so you have the most even weight distribution between the front and rear tyres as possible. If this is the case, then you'd want to run something a bit firmer in terms of shocks/springs. But this is just theory, someone with experience would be able to tell you more
