Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I'm switching to 18" Hoosier slicks all around on my 2007 NB GT3 from 19" street/ track Michelin cup 2. The fronts look like they will not hit the fender ok but 305/645/18" on the rear looks like a close call as to whether they will rub. I see a # of posts on Reenlist that say its ok, but I'm not sure the math adds up. The 18"s put the square shoulder of the rear slicks 2 1/4" below the fender measuring straight up from the hub. Has anyone tried this fit on their NB GT3?
