[MINI135i]

Anybody know the stock spring rates for the 135i?

Thanks.

Don't know the stock rates, but in a recent conversation with T.C. Kline about coilovers for street/track on the 135i he had just tracked a 135i with their c/o setup running 400 lb/in front and 300 lb/in rear. Said the car handled very well on the track and rode great on the street when the shocks were softened up.

I am looking forward to what TC Kline has to offer for the 135i. Good to hear they are working on the car currently!

I am looking at their DA Koni setup for sure, probably in the 500/400 range. I guess a little patience is warranted until all the testing is done.

It's always hard to know BMW OEM spring rates because they always use progressive springs or some non-linear springs.

On the 135i, the springs are a conical shape
