Feal 441+ (Road Racing version)

VQPAPI · 03-14-2024, 12:57 AM

I was wondering if anyone is running Feal 441+ road race versions on here? I plan to track my 370z fairly often as well as weekly canyon runs. The default spring rates seem to be 12k in the front and 5k in the rear. I was considering getting custom spring rates 16k front and 5k in the rear. I was curious about how these coilovers are. If anyone has these 441+ RR please comment or message me!

Im not too familiar with spring rates either. Is 5k rears optimal for time attacking?

Not familiar with them, but you’ll want a stiffer spring in the back, maybe 8k. Search around and see what other people are running

Late reply, but if you get this, please read this:
Aero and Suspension Tuning With True Type Coilovers

True vs divorced rear coilovers style significantly impacts what spring rates you want, with true types needing a rate about half what divorced needs
