A couple of things....
1) Dont start these threads, anyone, ever again.
2) Cutting a spring certainly does make it stiffer, because the spring rate (in force per unit length, e.g. lb/in, kg/m, N/mm) is a linear function of the length of the spring. if you make a linear coil spring 20% shorter, it will be 20% "stiffer". Thats a fact. i.e if you have a 500N/mm spring with 10 coils, and you cut one coil off, it will be approximately 550N/mm.
3) If something is TUV approved (like hottuning coilovers) its probably not "dangerous" in the sense that it will fail and cause an accident.
