Feal has developed a coilover suspension for the E90/E92 that allows you to run a true rear coilover option.
The spring rates for the standard 441 are 8.5k Front and 11k Rear Feal Springs, and the Front suspension comes with adjustable upper camber plates.
If you up-grade to the 441+ suspension that uses Japanese Swift Springs, the standard spring rates for this kit are 9k Front and 12k Rear Swift Springs.
If you would like to have Feal develop custom spring rates for your car to tailor your suspension for R-Compound tires, circuit racing, auto-cross, added down-force, etc. you can select the Road Race option.
If you are going to run the rear coilover option on this platform, it is recommend that you reinforce the rear strut tops.

Road Race Kit
For an additional charge, Feal is able to produce a Road Race spec coilover kit that is completely custom and hand-built. Based off of your vehicle data, Feal will select the appropriate Natural Frequency for your suspension and mathematically calculate the optimal spring rate to yield the targeted Natural Frequency. Only Swift brand springs are used.
Your shock cartridge is assembled in house from scratch with custom valving and super high viscosity index Maxima Shock Fluid. All Feal 441 Road Race kits utilize our digressive valving settings, custom damping profile, and calculated spring rate to suit your specific needs.
