I received my aftermarket carrera lights and PS2's tonight.
Rears are 47mm offsets, btw.
Brought them home and installed them before dinner, all excited to take the boxster out for a drive tonight, then decided it would be prudent to crawl under the car and insure nothing was rubbing inside before the maiden launch.
Wow. It sure is a tight fit in the back. I took my flashlight and my best guess is that I have about 3 or 4 mm clearance between the rubber and the strut on the driver's side, and the same on the passenger side, but in addition, there's a rod on the passenger side that's probably the e-brake actuator and it is about the same, 3/16th's inch away from the rubber.
My question is if this is enough space... Does the rubber and or wheel move or shift a lot under hard cornering enough to rub?
[clarification: Yeah, I know 97's aren't supposed to have 18's on them, and I am not planning to track the car with these rims on it, just drive around twisty roads and have some moderate driving fun, so please answer the question based on this information. Thanks!]
