Calling All Track Rats
What kind of spring rates are you running or recommend for a e90m? I'm going with TC Kline DA setup with hats and was looking for input on rates. I'll track some but mainly auto-x so I don't want much body roll at all. I will also drive some on the streets too, so it's not a track only car.

Call TCKline, they know what they're doing enough to design spring rates for you.

Agree with Car54...contact TCK, BimmerWorld or VAC. Discuss your suspension goals as well as other mods (e.g., tires, rim widths, etc) with them and they'll give you spring rate suggestions/options.

The best street and light track combo would be 350 or 400 front with 650-700 rear. See an extensive review on one of many TCKR DA's we helped set-up here: http://www.m3post.com/forums/showthr...light=tc+kline |

Was the SA on an E9x M car? Do you think the vehicle was at critical damping or slightly under damped? On SA kits, I don't recommend anything over 400F. |
