Being that my Gen 1 is fully modded you name it i got it . A lot of money spent to do everything right. My Gen 2 i know what i'm not messing with shocks, springs ,bumpers ,37's ,gears, exhaust . I just put wheels and tires on Gen2 few weeks ago stock sizes . I told myself if it rides rougher or handles different they are coming back off. So far they ride nice and are quiet. The only thing i am messing with is making it faster, tune , intercooler , ams tubes , thermostat , Throttlebody , spark plugs .
