Just to let you guys know I found a set of foams that are stiffer than stock that will fit your stock ST-PRO wheels and tires. The stock set of foams is not molded and is way too soft and nobody makes a set of LPR foams seperately. My LHS is closing shop and has everything 50% off so I got a set of OFNA part# 81101 foams just to see if they would fit and if I had to shave them down to fit. Well I put them on and they work. It is a tight fit but if you work the foam and the tire it will go on. Now the stock wheels are tires are much stiffer and should handle better too.
