soga280z Posted October 6, 2011 Share Posted October 6, 2011 hey guys, ive searched a bit but havent found anything on this topic, but does anyone know if a 13in wheel would clear everything on a 280z, with stock brakes. thanks guys. these wheels would not be for daily use, just for auto-x.

JMortensen Posted October 6, 2011 Share Posted October 6, 2011 IIRC my buddy's 510 wheels fit my 240 with just a teeny bit of grinding on the stock calipers. Tube80Z has run 13s on a 240, as has BRAAP, and I've seen them on an ITS 280, so it is definitely possible. Quote Link to comment Share on other sites More sharing options...

MidnightRider Posted October 7, 2011 Share Posted October 7, 2011 What's the advantage to such a small wheel? Quote Link to comment Share on other sites More sharing options...
beermanpete Posted October 7, 2011 Share Posted October 7, 2011 What's the advantage to such a small wheel? Lower gear ratio and lower center of gravity come to mind. Quote Link to comment Share on other sites More sharing options...
19762802+2 Posted October 7, 2011 Share Posted October 7, 2011 Lower gear ratio and lower center of gravity come to mind. Don't forget less unsprung weight/rotational mass so quicker acceleration and weight reduction. Quote Link to comment Share on other sites More sharing options...
Leon Posted October 7, 2011 Share Posted October 7, 2011 A smaller wheel+tire combo will go quicker, stop quicker, and have less unsprung weight thus improving traction. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted October 7, 2011 Share Posted October 7, 2011 (edited) If you look at pictures of Paul Ruschman's yellow autox car on 13's and compare to any Z that has 17's or 18's on it, you can see that Paul's car is lower to the ground, and the rear control arms are actually still pointing down from the center to the wheel, so the geometry isn't all F'ed up and he still has plenty of travel. At some point you do have to consider the possibility of smacking the chassis on the ground before the suspension bottoms, and some real low autoxers have skid plates for that reason. Terry Oxandale actually modded the struts to get his roll center back above ground in the rear of his extremely low Z with 17s, he's the only one that I've seen that has done it.
