X-member and strut top blocks should be minimal worry, I'm more concerned with the steering rack rag joint extension and the pitch stopper.
The pitch stopper should be fairly easy.
For the rear I was just going to go with WRX or SG Forester lateral links and axles, and extend my trailing arms an inch or so.
BTW I stuffed 28's on mine by using SG Forester struts.
Ive been running Forester coils on Legacy struts for a few years, gained about 3-4 inches, i was topping out my rear struts recently, so i picked up some Forester GR2's to hopefully fix that issue. But im wondering if i even have enough weight with my coupe to even get into the suspension, or if im just gonna top out like mad...:-\ times will tell.
Is it as easy as running WRX lateral's to fix the camber? im running bolts right now but its still a little positive. How were you planning on extending your trailing arms? My Castor is unbelieveable
I had 26.5" snowtires with the leg/for combo on my 97 Coupe
