interesting, the rear setup with the KW's doesn't seem worth the money since it isn't a true C/O setup. I've heard nothing but great things about the fronts though.
I believe they are a true coilover on the sra. Sra you would need to run a pretty wide wheel and tire combo to have clearance issues, even with coilovers. A friend of mine is running an sra with 335's and afco coilovers in the rear of his cobra and he is fine clearance wise.
