Fronts
1. Front upper control arm - the oem front camber is sorely missing in the S. I’ve set the new one at -2 degrees and it just hugs every curve now
2. Lower bushings - the lower oem links in the fronts have some really cheap hard rubber bushings. They twist a lot under load and that just ruins the driving experience. I replaced the bushings with MPPs sealed bearings. No squishy feel now
Rear
1. Lower fore and lower aft arm - the oem ones are non adjustable and they also have the same rubber bushings. With these two replaced, camber is easily adjustable across a wide range in the back. I set mine at -1.6 degrees. Works for me
2. Rear toe arm - the oem is adjustable but it’s a dumb 20mm nut size on the wrench. Also rubber bushings. I replaced this one too.
I’ve also kept the toe IN for both the front and rear at just under 0.04. My caster is a bit more than the spec, but that just keeps the car dead straight without any wiggling/drifting even at 120mph
I live in the ATL and took the car to J&M performance auto in chamblee (Atlanta suburb). Javier Mendoza the owner is amazing with racing suspensions and he knew exactly what to do to get these in. Then I got it aligned at Gran Turismo East (up the street from Javier). GTE is probably the best alignment place in Atlanta. They’re racing nuts!
I think the parts cost me about $4k and the install was another $1.5k.
My plaid is a freaking dream now! Tighter than a virgin
