Post Speedline 3.6 Wheels on a 964 narrow body

I am purchasing a set of Speedline 3.6 wheels off a 94' Turbo. Fronts are 18x8 52mm offset with 225/40/18 P Zeros, rears are 18x10 61mm offset with 265/40/18 P Zeros. I want to put these on my 1990 C2 narrow body cab. I have been told that I would need 28mm spacers to clear the oil lines by one shop and another has told me they will probably bolt straight on with maybe some minor adjustments to the oil lines and rolling of the fenders. Car suspension is stock but apparently has settled down a bit. Does anyone have this setup or have knowledge on what to do? Thanks.

Although people do run 18's on 964's, Porsche has only approved 17" wheels for use on 964's. That aside....

52mm is the stock offset, so the fronts are probably OK. 61mm on 10's shouldn't bolt on, as they would create interference. With 10" rims, you'll want your offset to be around 47mm, which would indicate a 14mm spacer. 265's should be fine on the back once you get the spacer straight. H&R makes spacer kits that also come with longer wheel studs, that you'll need to replace your existing wheel studs. Performance products (no affiliation) has a 20% off sale on through November 7th. Their Catalog shows $107.95 for a pair.

PS. The shop that told you they'd fit and would need rolling of the fenders doesn't know 964's. You may not want to go back there.

Tried 6mm spacers per the direction of wheelenhancement. The rear wheels/tires tucked in nicely but the right side rear was resting against the oil line! Took it back and exchanged for 15mm spacers, voila! Not sure the wheels/tires would actually tuck if I dropped the car but it does look good now! Thanks for the advice.
