The neuspeeds sports that i have on the are rated at 230-240 working rate front, 125-135 rear. The race, as i was told by neuspeed is 275-280 front, 155-160 rear. The H&R's are (I think) 300-315 front 185-195 rear. Alittle stiffer than the neuspeed. If your going to autox or race, get a higher spring rate. It's worth it. If it's for looks get the neuspeed for the comfort zone.
