Ive heard youre not supposed to mix spring types, but Im no expert.
Congrats on your car.
I sat in a e92 today and was very impressed, it reminded of low feeling of my E46 coupe. The day I first saw the E92s, I wasnt impressed, but the more I see the more I like. Thank goodness my E90 at least drives well or Id be really upset with myself for not getting a coupe.
