Friend of mine drove my car last night as my back was hurting, he owns a stock 2007 M Coupe. He was amazed at how well my car rides with the JRZs. Its sooo much better then his car.
They do a great job of soaking up the bumps and not just riding over them and not transmitting the impact of expansion joints and sharper impacts, especially on the hwy.
