Mclaren - track day tyre choice

[TISPKJ]

As i said somewhere above if I were doing again I would go one size under.
You can probably go on Michelin website and see exact sizes of cup 2's
If your anywhere near kent you can try one of my wheels on your car.
you need to pick up a set of secondhand wheels for track use and fit cups or similar.

So is any one running cup 2’s on a 570/540 series car ? If so are you running 285/35 R20 104Y rear fitment with 235/35 R19 91Y front fitment.

I have toyed with the idea of also going with a 295/30 R20 101Y XL N0 fitment on the rear to match the slightly wider front fitment.

You need to check if the wider tyre will leave enough space for the wheel arches. I don't have personal experience of the 5 series cars but on the 650/12c there wasn't really sufficient space for the michelin rear tyres at OE size nevermind wider without spacers. Tirerack has a quite useful 'tread width' measurement actually that you can use as some sort of comparison to the standard pirelli tyres as section width definitely doesn't tell the whole story.

a company called Apex at the Nurburgring are currently using Nankang AR1's but also testing a new tyre for next year. They are giving glowing reports on track for these tyres and maybe worth a look.

They are all over social media so not hard to find.

If considering going wider then spacers may be required, John @ Thorney and Mark @ Backdraft would advise on available and suitable options re tyre widths and spacers?
From reading owners group I understand sports series do not suffer from arch rubbing with Mich PS4S

Back to my questions.

Better to go to standard Pzero or Corsa?

Would not drive on wet but sometimes when is below 10deg, dry. Plus I would not mind few laps on track.
