As others have said, understeer is less. MPS mounted on factory 20” wheels. No problem

Thats a 305 you posted and a MPSS. That is neither a 325, nor a Cup 2. (I think dude was calling BS on 255/325 Cup2)

MPSS = PZero
MPS4S = Corsa
MPSC2 = Trofeo R

If you went same size from PZero to MPSS, there would be no real difference. For an up grade you should have gone 4S. (The S is important as there is just a 4 as well which I think replaces the SS)

325/265 MPSC2s on 19" E88s, 11.5" wide in the back. Love the ride, increased front end grip and feel.

Logic for 325/265 is that its a 20mm increase rear/front from my OE 315/245 (sport techno) setup.

I would, and probably will run the same setup on 20s.

Have a c2s, running on 20x9.0 Et45 11.0 ET55

Lowered with PSS10 Damptronic

Planning to get MPS4S

Suggestion for tire width? 305 + 245?

Thanks

For looks you could go 305, but if you want performance, then a 295 would be better on an 11 inch rim. The GTS now have 12 inch rim the same as GT3, so the 305 is a no brainer.

thx for the feedback, what would be the difference in performance with 305 on 11"?

A baggier tyre, will squirm a little when you are hard cornering or tracking. I have ran a 305 on a 10 inch on an M4, and it was baggy. I wouldn't do that in a Porsche, as they are rear engined and go around corners harder and put more pressure on the tyres.

On an 11 it will be OK, but if you want to set best lap times on an 11, then 285 would be the go. Just think, 300mm is 12 inches, so a 305 is perfect for a 12 inch rim.

280 is perfect for an 11 inch rim. There isn't a 280, so 285 is perfect.

so the proper way to do is to get a 12' wheels? would spacer do the trick? or it has nothing got to do with spacer?

Maybe he was an avid lurker and you struck a nerve with him? Tread lightly, he may show up at your door.

A spacer has nothing to do with it. You want 12 inches of rim supporting your 12 inch tyre. A spacer just moves the rim outwards to fill the guards.

Has your acceleration suffered? I love the idea of the setup but it sounds heavy pushing those barrels around.

Thank you so very much for posting.





4point0, thanks for pics. Yes, your wheels, color and tint are awesome! Get those Cup 2s on back there asap.. I like where you're going with the 305.

I am also a confirmed "ratbag" on the street.
