Help with front wheel fitment (rubbing issues)

[Preston Garcia]

This will be a long post but here is some quick steps to follow.

What the car had when I bought it: Steeda lowering springs on stock struts with 20x10" rims and 285 35 r20 tires on the front.

Issue I ran into: The insides of the front tires were wearing aggressively and showing wire.

Suggested fix: install adjustable coilovers to remove the toe and some of the camber

What I did: Installed SR Performance Coilovers

New issue: Tires are too wide and rubbing the coilover assembly, cannot adjust spring load or lower car.

My idea: Install 20mm spacers to gain clearance $180

Issue/question concerning my idea: will I rub on the fenders (when turning) because the rims are 20" and 285 tires.

Alternate (expensive) idea: Buy the same style rims in 20x8.5 and install 255 size tires. $1,400

Alternate (mid range) idea: Put the stock assembly with steeda springs back on and install camber plates to bring back stock camber. $550

So, as you can see I am currently down a rabbit hole of unexpected repairs, I'm wondering if anyone has ran 20x10 with 285 tires and 20mm spacers in the front and can provide some input? New wheels and tires would run me about 1,400 and I would rather pay 180 for spacers if the fitment would work correctly. The spring pre load is jacked wayyyy up because the spring will come in contact with the tire otherwise, to set the normal pre load, I must gain clearance, hence the concern. BTW, all of the alignment and adjustments were done by the NTB (national tire and battery) manager, he seemed to know what he was doing but I'm not sure.

Hey this is Junior from Project 6GR, from what it sounds like is the offset on your wheels must be wrong for the front. What are the exact specs for your wheels up front? Here at 6GR we use a 20x10 +35 285/35 for the front and we have no rubbing or clearance issues on these mustangs. Here is my personal car for example lowered on BC Racing coilovers lowered about 2 inch's with the our 20x10 +35 285/30/20. I have plenty of wheel to strut clearance and no rubbing on the inner fender. Feel free to give us a call if you have any fitment questions.

Thanks for the reply, great looking car btw. My offset is +40mm, I ordered some 5mm spacers off amazon, I believe that will give me the clearance I need.

Looking for an update to see if you resolved this since it seems like I’m encountering the same issue. For a few months I have been running the Pedders SportsRyder Strut/Shock system and previously had a 275 front and 285 rear tire setup on 20x9.5 +30 offset with no issues. I just replaced the front tires to run a square 285 setup earlier this week and yesterday noticed some rubbing when I would go over an overpass or bridges on the highway. Very notable audibly. I don’t feel or hear any rubbing at any other time but when the shocks compress due to the road bump.
