Will 305/35/19 tires fit with Ford Performance Cobra Springs

[maddseason]

All, i'm the proud owner of the 2020 Mustang GT PP2. I recently swapped the SC2s for Nitto 305/35/19 tires, Stock tires are 305/30/19s.

I bought the ford performance cobra lowering springs these ones. These will drop the car 20mm. My question is does anyone know if the 35mm sidewall is going to have clearance issues in the Front when turning the wheel.
I'm stupid as I should have gotten the 305/30s but swear they were not available when I looked.

Should be fine there is still gap.

Im not concerned about the gap it's the space inside the wheelwell. The stock tire was 30mm, the Nitto's are 35mm. I'm worried i won't have enough room to turn the wheel and it will hit the inside of the fender. i'm just wondering if antyione has experience with using these springs with 35s vs 30s.

Seconded. Have not seen them with those exact springs but with ones with a similar height and a 35 aspect tire they were fine. I'm getting ready to order 4 Michelin Pilot Super Sports in 305/35/19 as well on BMR Performance springs and spacers.

The 30 and 35 is not mm, it's a ratio of the width of the tire. So a 305/30/19 tire, the 30 is 30% of the with of 305mm, 35 is 35% of the 305mm. That's why a 35 aspect ratio will be taller than a 30 aspect ratio given the same width (305mm).

It should fit fine...

So springs were not installed. I called the ford dealer and gave them all the info, and they know I have the PP2. They quoted over the phone approx $500 to install the springs. I brought the car to the dealer to have the job done and then after 4 hours waiting they called me and revised the price to $1500 and told me that it would take 10-11 hours because there is a lot of adjustments to make because of the magnaride suspension. But Bill on CJ installed them on his 2018 magnaride car and said its like a 4-5 job. Oh well. I'll be waiting now to install them.

Good LORD! 1500 TO INSTALL SPRINGS?? My guy at the dealer quoted about 750 for the springs and install. They are really telling you $1500 for just the install?!? I also have a PP2 and he/they know it is a PP2 with MR Suspension. You were smart pulling the plug for now. I will be having mine done fairly soon and will chime back in.

Yes. They said it was very complicated and that there are lot of adjustments to make. I think it's a bunch of BS.

It is a bunch of BS. I did it myself in roughly 4 hours and then after a week of regular driving (to let the springs settle) took it to get aligned at a performance shop. Car rides just as good or better now.
