Roll Racing 3.15s?

[joshwwua]

Hello, I own a 2018 mustang gt a10 base model so i currently have the 3.15s. Just finished installing all my go-fast parts and i am stuck on wether i should go with a 26” or 28” tall tire on 17x10 wheels. Car will be seeing rolls for the most part. Maybe some digs every now and then. 40 and 60 rolls. My car has ported cj, vmp monoblade, d mark cai, american racing headers paired with corsas extremes and tuned by a local guy on e85.

Unless you are trying to meet a very specific goal (cross the 1/4 mi mark in a specific gear), I don't see any reason to deviate from stock tire diameters. Plus if you want the speedo and odometer to remain accurate, you'll have to program the new tire size in the ECM.

Since you're staying N/A I would personally recommend sticking with a 26".

I don't know of many that go with 26s on s550s honestly, even on a bolt on car I would personally go 28s.
