clarkspeed Posted May 3, 2017 Share Posted May 3, 2017 I uploaded a simple roll center calculator for a S30 in the uploads section. http://forums.hybridz.org/files/file/34-s30-rc-calculator/ I developed it because I like to set up my suspensions using the control arm angles. Fast and easy. If you need more info on what a RC is or does, there is large amount of info on the web. There is also plenty of debate on this forum on where you should set the RC and I wish I could tell you the best place. But when suspension tuning everything is a compromise and "best" is usually a combination of things, depends on your goals, and will change from car to car.

260DET Posted May 5, 2017 Share Posted May 5, 2017 Good one, a starting point for roll centres would be rear at the bottom of the diff, front a bit lower so you can tip the car into a corner and roll will be manageable. Quote Link to comment Share on other sites More sharing options...
TUME Posted May 8, 2017 Share Posted May 8, 2017 Just checked my calculations about roll-center(s). Seems like in my car r-c is ~65mm front and ~115mm rear. Should be decent compromice. Bit of a job to get those figures, with my "modified" suspension. Quote Link to comment Share on other sites More sharing options...
