timtiminy 0 Report post Posted September 26, 2019 Figured I’d ask if anyone knew the f+r motion ratios for the x8 chassis. Don’t want to have to actually measure if someone here happens to know. I know most don’t care and just run the 12k 8k springs that come on off the shelf coilovers. I’m gonna rebuild some coilovers with Bilstein pistons and valving to suit the springs I end up picking. I’m gonna have to measure unsprung weight at some point so if no one knows the motion ratios I’ll post them here when I get around to measuring them. Share this post Link to post Share on other sites
Gordo 0 Report post Posted January 7, 2020 Three months, did you ever get around to do all this measuring ? How about dealing with unsprung weight by digging through the scrap yards to see if any of the late model Lexus rear uprights that are made out of aluminum come close to fitting the X8. What do your wheels weigh? If over about 15 lbs each, you are already making wrong choices. Same with brake rotors, what do yours weigh? While you are at it, measure unibody flex at those spring rates, to see what is moving more, the unibody, or the springs. I keep forgetting that I own an ex-Tokyo taxi, and not a Formula-1 car. I dream of having Rue change jobs, so he is around a 5-axis mill, and could whittle out uprights out of blocks of titanium, or titanium hubs. I salivate when I see ceramic coated titanium brake rotors. Considered buying titanium bolts for everything hanging out by the wheel. (spend thousands to loose 5 lbs of unsprung weight). But then I come to my senses, and remember what I have, and unless I win the Power Ball, none of the cool shit will ever happen. Share this post Link to post Share on other sites

Contact Shockworks and see if Chris will provide, he built JZX81 Strut's off a stock car and took all the measurements to produce there off the shelf kit. he might not help but no harm in asking.

Gordo 0 Report post Posted March 2, 2020 Wow, 5 months, and no motion ratios yet.... (might as well get in a few digs before the place is gone) Share this post Link to post Share on other sites
