Steeda progressives riding on 275/305s

[aggieStang]

Just finished my install of my steeda progressives and my new rim/tire combo. theres plenty of writeups so i will skip straight to results.

275/35/r20s on 20x8.5 fr500s in front and 305/35/r20s on 20x10 fr500s in back

This thing rides lower than i thought it would but it handles very tightly now. the 305s rub slightly on harsh bumps.

Anyone running drop coils on 305s, can you fit your finger between the tire and the fender?

Lastly, i did notice TONs of stuff getting kicked up so i will be installing my anchor room clear vinyl to the rockers/fenders until i can make my rock guards on my 3d printer.

Thanks, I have 20x11 with a 59mm offset in the rear with 315 INVOS no rub.

Do you have any fender gap or are your tires tucked? Mine pretty much tuck into the fenderwell.

Awsome gonna have the exact same setup as you except my new rim is 38mm offset I'm not too familiar with offset it that a big difference compared to yours?

I think the reason is you went with the wrong aspect ratio. You increased the tire diameter quite a bit over stock. They should be about 27". Your rear is 28.4" and front is 27.58. While the fronts aren't off by that much, the rears could have easily gone down to a 30 AR and would have been close to the same diameter as your fronts @ 27.2". I'm betting it's the rear where you have the trouble.

I wanted to increase the diameter. I wanted as much rubber back there as i could squeeze in. Others were running the same setup with no rubbing so i went for it.

As an update: i got the steeda cradle alignment bushings and now there is absolutely no rubbing. after the car settled i realized the cradle was offset to the drivers side by about 3/16". Now that it is centered, the fitment and ride are perfect!
