im going to get the spl subframe bushings (solid) and was wondering if i should get the urethane subframe spacers as well? i already have the zeal coilovers, car is NOT a daily driver mainly just a weekend cruiser and possible track car here and there, comfort as with the coilovers are not primary concern, wheelhop/handling would be preferred, not really concerned about the noise as the exhaust is deep and masks a lot of noise and if that doesn't work i just turn the radio up :D so thoughts before i make the purchase?
