Hey all,

Curious if anyone is running F 315 R 325, 325 squared, or F 315/325 R 335.

Also, does Forscan or any other aftermarket options offer the ability to change the tire size for speedometer accuracy?

Pulling the trigger on something in the next 2 months and the GT500 CFTP is at the top of my list right now for price/warranty/automatic (wife...) reasons.

It's the hand I'm dealt with and I'm just glad she is letting me haha. My daily commute is 100-150 miles depending on which site I visit so 3-4 days/week I'll be taking the MPG car and she will be driving the other car so I'm just glad she's letting me get something sporty lol.

you can do 315 squared according to Apex fitment page. Ive seen people do 325 but you will need to get the proper front offset. Anything more than 315, I would recommend a 12" wide wheel

https://support.apexraceparts.com/h...3-S550-Mustang-GT500-Wheel-Tire-Fitment-Guide

Wheels


  • Front & Rear: 19x11.5" ET56
    • Available in: SM-10, VS-5RS
    • Track alignment highly suggested, around -2.5* front and -1.5* rear is a good starting point
    • 31mm or larger spacers are required up front, along with GT4 or GT350R spec wheel studs, and open lug nuts
    • No spacers are needed on the rear
    • Select aftermarket coilovers with offset housings allow the use of 25-28mm front spacer. The only known coilovers are JRi, JRZ, and MCS. Please contact your suspension manufacturer to determine if your coilover not listed here has offset housings if you wish to run less of a front spacer. Most do not.

Just don't try to stick those 19's on the front.. You'd need 350 components to do that.
