A High Performance Spring has a high stiffness to mass ratio. In other words, it is light weight for a particular rate. This requires the finest materials. And, of course, you want the specific rate you’re paying for. Most manufacturers hold rates within +/-5%, this means a spring marked 5.0 kg/mm could be a 4.75 or even 5.25. (A spring marked 5.0 could be the same rate as one marked 5.4!) Race Tech Springs have extremely accurate rates because we 100% test our springs. Chrome silicon, high stiffness to mass ratio, shot peened, heat treated and pre-set (no sacking). These are the finest springs available, period!
