Got some things accomplished last night. *PS* the underbody is dirty, I just drove across the country, usually I detail it once/month so no comments about the filthy underside, please
- Installed the stud kit, not sure why I didn't do this one sooner..
- Raised the rear suspension, which req'd removing the springs etc. due to literally no room to turn the adjustment wrench

And guess what, it resulted in about a 1/2" too high, so I'll be adjusting that this afternoon prior to my alignment.
The car drives fine but rubs up front due to the current lack of negative camber. IIRC, I set it up just around -2.0 so I'd have good wear, but that's not enough for this setup. Will require minimum -2.5 to -2.9* imo, we'll see. I set the 3-way damping to KW's "track" settings, and the car came alive last night.
Overall I'm very happy with this setup for DD and tracking for this year. I still 100% intend on running a 9/5" wheel up front, next year. So stay tuned for that over winter, among a few other things (m235iR oil pump, aux radiators, brake duct work, weight trimming).
Here's the turn of events from the install and initial fit (sorry for the pic quality, just an old iPhone atm):
Ready to go on
Here's the clearance for the coilover/tire with the 18x9 et42 and 255/35 RE71R (they run wider than most). A 245 would take 1-2mm away, and an 8mm spacer, another 2mm, which would be ideal for the 9" wheel IMO, or a 235/40.. When I go 9.5", I'll still most likely run 255's, but square.
After I set the rear ride height dial in the alignment, today, I'll give the car a detail it's been waiting for, in/out and underneath. Until then, cheers
