Moving from PSS to MP4S on HRE P101 - will it rub?

[tomfraser]

Hi all - my rear Michelin PSS are just about down to the wear bars, so time to replace, logical choice is the MP4S, but from everything I have read they run wider and have a more square shoulder than the star spec PSS.

I am looking for some advice to confirm if I can remain same size, or if I should drop by 10mm.

Current setup does not rub except very occasionally in the rear when I go over a large dip/bump - car is riding on MP HAS suspension.

Wheel specs -
Front - 20x9.5” ET20
Rear - 20x10.5” ET32

Current Tyre Spec
Front - 265/30 20
Rear - 295/30 20

I have mps4s with 265/30 and 295/30 lowered on coilovers with out any rubbings. You’ll be fine.

On an M3? That's pretty aggressive 10.5 +32 will rub a bit depending your lowering spec/height as well as camber.

285 is actually the better fit for that width and offset, but if you're not lowered much 295 is OK....

What are your wheel specs?

Yeah, M3, not super low, I would say rear is actually pretty much stock height - I would like to stay with 295s as I love the meaty look, but I drive the car hard, and any more than the slight rub I get on max compression would not work.

Pics attached of current height and poke.

I’m on bilstein coilovers.
