On a smooth-as-glass racetrack bilstein will perform better, on daily driver roads koni can be made more comfortable. H&R springs are too soft for how much they lower the car, especially the rears. If you have to run H&R fronts at least get a decent 400 or 500lb coilover spring to put in the rear. You could also call ground control and ask them about coilover converted koni sports, I'd do that as a budget friendly, comfortable, track capable set up. A quality coilover setup is worlds above a shock and spring combo. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
