Finally ordering up some UHMWP But I ran into a few problems. Theres some info I need but dont know. how thick should the uhmwp be for lining the rear springs. These are the thicknesses they offer: 04" | .05" | 1/16" | .08" | 1/8" | 3/16" | 1/4" The springs are 2.5 inches wide. Should I buy 2.5 wide stuff or should it be wider? And how many inches of this material will I need to do both rear springs. Thank you!
