Track Day Wheels / Tires / Sizes / Compounds

I have an upcoming McLaren Experience Track Day coming up.

I've done 100+ laps at homestead on the stock wheels / Pzeros and then replaced them with PS4S.

Any help would be appreciated:

What wheel sizes are available that I can mount slicks to the car for the track days?

If I stick with stock rims, what slicks/sizes are available?

What is max width/size tires that will fit on OEM Ultralight ten spoke wheels (2019 570S Coupe)? Do engine throw codes with different wheel heights?

What non-slick but high grip tires are available to fit OEM wheels?

Thank you for your input

Albert

Going to a properly engineered set of track wheels has a lot of advantages, the first being sizing, as stepping down to 19 dia square" opens up a LOT more tire options and provides a lot of performance advantages. It also inherently makes for a lighter, stiffer wheel with improved moment of inertia characteristics.

For the 570 we've done a few configs, but 9/11" widths work well. You can run 235-245 front and 295-315 rear. The key is just keeping the OD of the tire front and rear as close to stock as possible.

Most of our customers run Hoosiers, Cup 2's, or Trofeo R's.

I am running Sport Cup 2's on my 570 235/35/19 and 285/35/20 rear. From driving the car on stock tires I found that it needs more front stick, not so much rear. Hoosiers stick great, but "purple crack" is expensive and doesn't last long. Tropheo R is a great tire, but I have seen drivers go through a set in four days of open track driving.

I only got about two track days on my Trofeos at Thunderhill. FYI.

Gtracer37: I agree completely. The front is where more grip makes the most sense

I've never been a fan of the Zero's. The sizes you're running make sense

How much you think is left on them? I want to do them for my Track day soon but wanted to get a little more road use as well. I don't expect a ton.

Pagid makes a race CCB pad. It should last longer than stock pads. They are less than $1500 for front and rear pads.

These are the SAME BRAKES as on the new Ferrari V8 cars, as well as the Corvette and Camaro ZL1. I have not checked if the bolt pattern on the hats line up but rotors from the Chevy dealer are MUCH less than from McLaren dealer.

Anyone have a part number for the Vette rotors?
