2008 ISF factory stock ride height...

[Jon Dee]

I'm currently researching wheel/tyre/suspension combinations for my ISF but need a reference point. My car is on coilovers and aftermarket 19" wheels so I don't know how much lower it is from the factory wheels/tyres/suspension height . 

If there is someone who is still running the full factory setup, I would be most grateful if you could measure the ride height with the car parked on a level surface. If I could get a measurement from the ground to the top of the fender arch and a measurement from the ground to the hub centre for each wheel, that would be perfect :)  Here are the measurements from my (lowered) car for comparison with a totally stock setup: FR 655/313, FL 660/313, RR 656/305, LR 650/305. Thanks in advance 

Cheers...

I take it you have read the american forums on this subject? If not, there are quite a few:

In that link is the official way to measure the height, not the most convenient but apparently correct. Various other measurements etc on there. Personally I am going back to standard shocks soon as I don't like coiovers on a daily.

Big thanks to you sir :) 

Lexus isf stock ride height is :
front 26.750(679.45mm) and rear 26.000(660.40mm)
measuring from the ground up through the center of the wheel to the fender 

I had followed a link that took me to the complicated (but technically correct) method of checking ride height, but did not scroll backwards from that post, so missed the above gem. I'm 96.748% certain that I will go Bilsteins and 18" wheels to improve the ride quality. Also considering if I need the Swift lowering springs (similar rate to OEM) for looks. 

Cheers...

I run Swift springs with no appreciable reduction in the ride as a result.  Would certainly recommend them….
