Dont quote me on the S10 shocks, I'm not positive they are shorter but if I remember correctly they are. Thats the problem with lowering springs, at least these keep a good spring rate instead a weaker rate of the longer springs. I'm going to look into the shocks once I start playing with the Regal a little more. I still would rather have the 5413's or BellTechs that Hotchkis or Eibachs because of the better ride quality but the short spring does need some work, thats for sure!
