I have my own set of (I think non-reinforced; need to check) FDs for autoX and this thread is a godsend. Still trying to gather all the info I need in terms of spacers and fitment on a sedan.
I'm running the same MS greens Justin ran for a while, with b-spec springs. From what I've gathered, I could run either a 3 or 5mm spacer in front (no need for hubcentric right?) unless I grind off some of the strut tab, and a 3mm spacer in the rear to make up for the lack of complete "boring" of the wheels to fit over the hub.
The other thing I'm not sure of is if a 225/50 will fit in the sedan without needing to roll the fenders...
Any advice is helpful as a lot of the info here is for a P5...
