Bigger is better. Not sure why you would want a smaller tire or rim on front. On my 2015 GT PP1 I had a square setup 275/40/19 on front and back. In winter I had some square 20 inch rims and used an all season 265/35/20. The 19 stock will clear the pp1 brakes and so did the 20s. The 18’s you propose won’t work!


Bottom line using an 18 inch wheel would be a mistake because of Brembo brake clearance..you have to have a 19 or 20 ..go big (er) or go home!
