I have the HR coilovers on my 14 S4 for 2 years, while adjust the front and rear height today I found that the front is a 0.5 FTG inch lower than the rear, so should the front lower or higher than the rear? Or it should be the same FTG for all? what is your height setup? And I also found it is really hard to raise the front coilover up, do I need to take it apart or use a spring compressor?

I used the following from the Stasis challenge installation manual, page 17.

The file above is for the B6, B7 cars. For the B8/8.5 Stasis recommended front at 13.5" frt, 13.3" rear with 3/4 tank of fuel and driver. On my car adding the driver (200#) dropped the car another~ 3/16". I run mine just slightly higher at 13.7" frt, 13.5" rear. They recommend min height at 13" frt/rr.

The motion ratios are slightly different on B8/8.5 at 0.65 fr, 0.8 rear when trying to calculate how much to change the collar height vs the wheel/ride height.

My bad on the link, it appears the link I saved is diverting me the the B6/B7. Regardless, an 1/8 in (.2) rear rake is recommended. My FTH height is greater as I run 275’s, but I keep the same rake.

Note, these numbers are wheel center to fender. Bc tire brands, models and sizes all affect ground to fender figures it is tough to provide a recoomendation. Mine are roughly 26 5/16 frt, 26 1/8" rear wo/driver (ftg) on 255x35x19 Mpss AS/3 on peelers.
