2003 Lexus GX470 im working on switching it over to coil overs for the front and coils for the rear but if ya'll could help me with some recommendations. Or even if ya'll know of any good complete kits. I also understand that some mods need to be done to the rear in order for some coils to fit right, if i can get a answer to what exactly i would have to mod it would be helpful. Seeing as i will be doing the work my self
