I bought an ap1 it came with coilovers, adjustable ball joints, has rolled fenders. My question is what size of wheel and tires can i fit without stancing it? the previous owner had 18" but couldnt remember the diamentions.

Staggered you can fit 17x9 +45-63 in the rear or maybe 17x10 +55-70ish. Up front you can fit up to a 17x7.5 +45 or a 17x9 +63 but you may run into inner clearance issues with the 17x9. These are all assuming a couple degrees of camber but nothing excessive at all. I'm running a 255 on the rear of my 17x9 +45 wheels right now but the tread width is only 8.2" so the tire is is little stretched but it looks like a performance stretch rather than ricey stance stretch, and I'm only running a max of 2* camber on the rear with 0 rubbing and less than a 1 finger gap. Not sure of my exact alignment specs Cuz I just lowered my car and I'm waiting on my new tires before I get an alignment. There is a sticky on which wheels will fit under stock fenders but with fenders rolled flat you can add ~10mm of outter clearance to those numbers.

A good fit if you want to run 17inch with rolled fenders will be 17x9.0 +45ish 255/40 all around. That is with front fenders roll flat and a little flared. Rear bumper tab relocation and rolled flat.

17x9 +45 with 255/40-17 isn't a what I'd call a good fitment, even with rolled fenders. +45 is a bad offset if you want to run wide tires. Particularly if "stance" is not desired... If I wound up with that width/offset all around and had to use them. I would go with 235/40-17 fronts...

Enkei PF01 come in 17x8 +50 and 17x9 +60, easy fitment with 225/45-17, 255/40-17 tires. Or run 17x9 + 60 all around with 245 square or 245/255 staggered tires. No worries... Could probably do 255 all around as well if desired.

I'm currently on 17x9 +48 lowered on 245/40 squared Michelin pss. No issues whatsoever. I am rolled and tabs relocated.
