Started prepping my car for STU over the past couple months:
New rear subframe with Whiteline bushings.
Kinetix A-arms (modified for more negative camber)
And yesterday, I mounted new tires on new-to-me wheels: 275/35-18 Rivals and 18X10.5 +15 RPF1's
Custom valved/sleeved shocks + much stiffer springs, and HP is all that's left.
Well, I also need to remove my 10W6, custom MDF enclosure, and big JL amps.
I'm going to miss the heavy sub/enclosure, but I bet that and the amps total somewhere between 60-80 lbs.
