Would I be able to run a 19x10 with a 305/30/19 setup up front? It’s a stock suspension 22 2Ss no MRC

Yeah, but 10" is a bit narrow and out of mfg'ers recs, so a lot of shops won't mount them and the Bridgestone RE71RS are difficult to impossible to mount in pinched applications. I'd avoid doing this personally, pinching isn't faster and steering feel is more vague. I'd look for 285s if possible.

My issue is that i unfortunately already purchased the 305/30s as I lucked into an oem set of ZLE 19x11 wheels but they did not fit on my car, which is why I was hoping to size down and keep these tires as I intend on running a 325 rear

ZLE wheels definitely fit, little poke w/o camber but camber is good.

How were you able to get them to fit?

[DaveC113]

Didn't do anything, but I think you'd want at least 2 deg camber. If you drive on curvy roads and set to zero toe your tire wear won't be excessive. In the pics camber is about 3.5 ft/2.2 rear.

The middle pic is with oem sus, top and bottom are after I installed MCS coilovers, so it's a bit lower (~1") and still fits.

Everytime I attempted to mount them it seemed like they were hitting something that prevented them from going on, I don’t have MRC and I am on factory alignment spec if that matters

Interesting. Might be the strut. On MRC we often have to grind the strut just a little bit to clear 19s, but I thought non-MRC had more room. It takes about 5 min each side, it's not much work. Apex wheels fitment guide has more info on that.

Do you have any more photos of the stock suspension?

Yes, sometimes w/a harness reroute, but this is bad for cornering, it makes your sidewall floppy. That said, im on 295 fronts on two wheelsets, but personally I wouldnt go for 305 w/o a wider wheel.

Ideally id run an 11’ wheel but I was having issues mounting them, and I’m honestly not sure why

That is odd. Not sure I caught which brand tires you bought. But here is my experience if it helps you. I have an oddball old wheel that is 10.75”, not 11”. I have mounted the old Re71s and Nankang brand , both 305/30/19s with no problem, re’s being a stiffer sidewall, the nankangs being actually wider but a softer sidewall. Both fit no issues. Now my re71rs in not a 305, but 285/35 on that same wheel, had to be set in the sun to soften them up and also needed 100 lbs of air to seat them. No issues there but shows how stiff they are and not pinched. Also they are on a wheel almost max width and slightly stretched. This way they grip and handle great and do not have a lack of response. These tires are only a 1/2” less in actual tread width that is used vs the wide 305 nankangs that also run wide. I have a friend that has 305/30/19 re71rs’s on 11 wheels. Broken in vs my 96 run tires. In autocross he has gained no ground on me.yet anyway.

I bought a set of Bridgestone potenza RE050A, everytime I attempt to mount the oem ZL1 1LE wheels with those tires, there appears to be something blocking it, which throws me off since I don’t have MRC meaning that I should have enough clearance?
