305 squared for track

[Bruzer]

Hello everyone, I recently bought a ‘21 base model 500 with handling pkg and would like to replace/preserve OEM PS4s with something else. Not a lot to choose from in 315 sizes so considering 305 squared. I do plan on tracking. Opinions please. Thanks

Something to consider is will you be using the oem wheels or will you be using a aftermarket squared wheel setup?

Planning on using OEM w/all being 20x11.

You do know you can not rotate the stock wheels front to back difference back spacing.

I wasn’t sure. I looked it up on Wheel-Size.com and entered my car info and it lists an et of 32 for both front and back

Above is correct. Different offsets.

I would double check the offsets on your actual wheels to make sure they are a true square fitment. If so the 305 square will work fine on the 20x11.

Ok, thanks for the replies. I’ve run 285 squared on my M1 and like it vs staggered, but didn’t know about the gt500.

305's are a little skinny for the power level on the rear. The car has a lot of torque and it can make it hard to put power down smoothly mid corner and on the exit.

If you are in Aubrey I'm just a few miles up the road in pilot point. I've run 305 squared, 305/315 305/325 and now 325 squared. The car responds well to 315 or 325 rears. Fronts work with all sizes, the smaller ones just tend to overheat faster if you are pushing hard.

That’s what I needed to know, thanks for the info. Much appreciated!

If you're looking for a tire just for track days and not going for any records, the Continental ECFs are a great choice for longevity.
