18" Fitment & Clearance Calculations / 944 Early Offset
Have a line on a used 18" wheel tire combo but need to exercise the collective brainpower here. Car is 85.5 944 with early offset. Currently have 951 Fuchs on the car with 23.3 offset. The prospective 18" tire / wheel combo is as follows:
F: 8.5 x 18 ET 52 with 245/35/18
R: 10 x 18 ET 48 with 285/30/18
Obviously going to need spacers, thickness TBD but wondering if there are any interference issues overall? Fender and / or suspension clearance? Searching the forums turned up a few threads where 285/30/18's fit (with spacers) on the rear but they were mounted on 996 twists which have a ET of either 65 (narrow body) or 40 (wide body). The OP didn't specify offset:

Another thread here:
https://rennlist.com/forums/944-turb...set-951-a.html
In the first post of that thread the OP stated:
"Largest wheel fitment without fender modifications: Front 18x9 et 52 with 1“ spacer, Rear 18x11 et 45 some cars may require 1/4" spacer and should require the top shock tower bolt to be reversed"
I posted this on the 944 forum as well as the car is a NA however I have all the parts needed to complete a turbo brake upgrade and wanted to post here as well.
Shot off a few PM's and emails to the OP's of those threads but wanted to get as much feedback as possible. I know stuffing this combo under the fenders is like trying to fit 10 lbs. in a 5 lb. bag but I'm considering it if they can be shoehorned in.
