I ran 32-36 cold and saw up to 44 hot = this was at the suggestion of Michelin's Motorsport Engineer (Michelin owns BFG).
There are some BMWCCA e36/e46 guys that complain about the progressive springs that come with the KW CS and have them replaced with linear springs of the same weight. Can you confim the rate and if they are linear vs. progressive?
CS normally come with linear and V3s come with progressive rate springs I think.
