Has anyone that has changed their factory 16" wheels to factory 18" polished, chrome, or black bullitts have to use steering stops as stated on Ford Racing web site.

Note: For vehicles with 16" wheels from the factory: -installing 17" x 8" wheels, use steering stop 4R3Z-3932-BA -Installing 18" x 8.5" or 18" x 9.5" wheels, use steering stop 6R3Z-3932-CA
For vehicles with 17" wheels from the factory: -installing 18" x 8.5" or 18" x 9.5" wheels, use steering stop 6R3Z-3932-CA

 

I read that same thing yesterday while thumbing through the FRPP catalog at a local performance shop. I put 17x8" Ford polished Bullitts (with 235 Pirellis) on our '05 vert without changing the steering stops. Never had any issues. There MAY be a concern with 18" rims though. The add'l expense could be worth it, but I'd suggest waiting until the wheels/tires are on the car to see if you need them before pulling out your wallet.

 

+1....no problems with the 17x8 but dont know about the 18s. havent read of any members having this issue that have installed 18s.
