Pirelli P Zero Corsa diameters...

Front: 255/35-ZR19 measures at 25.94" OD
Rear: 285/30-ZR19 measures at 25.88" OD

Unloaded but inflated and mounted. The true rolling circumference would be fractionally less than Pi times the OD due to the tire flattening against the road surface when loaded.

Okay. Can't argue with those numbers. Would be curious to see what the 245/35's measure out at.

Don't know, that size doesn't seem to be as readily available and I wanted the GTS setup.

Yikes! $2600 for a set of tires.

The research I have done indicates the same. The wheels are 9.5 in front with et24 and 10.5 in rear with et24

As far as weight goes....I'll be reducing weight by 6lbs per wheel with WedsSports. Realizing the 295 Hankook rubber will most likely weigh a bit more than the 265 Michelin OEM's.
Interesting combo bro! I am looking into getting a set of COR F1 Brava for my ride. I see that your new wheels are slightly wider than ZCP wheels by 0.5" per wheel. Are the new wheels doing with the same offset? I am concerned with rubbing. I was told that COR goes aggressive with offset for that flush look while guaranteeing no rubbing. All these talk of tire upsizing is rubbing off on me

I'm not sure what the ZCP offsets are. Here is a pic of my new setup on the car. There is no rubbing at all. Now I'm debating whether I need to lower the car just a tad. I suppose by bringing the wheels further out to a more flush look actually shows the true wheel gap as opposed to if it's tucked a little back like the stock offsets provide on the OEM 220'?

Nice wheels bro! U are right on the flush look accentuating the wheel gap. Reading about the rubbing issues faced by some members here, i think i should just order the COR wheels with ZCP wheel offset (ET31/ET25 F/R) in case i decide to upsize the tires later on.

Thanks. I can really tell the difference on the contact patch with 295s on the rear. Just hooks up considerably better.

Those Brava's are nice wheels. Was at a car meet in October and two guys had them on their M's. One had the Brava and the other had the Cipher concave. Both looked great. I know that the Yokohoma and Nitto tires run big so that may be a factor as well. The 'Kooks that I got have a more rounded shoulder much like the stock Michelins.

I could be wrong but in the pictures it looks like your directional tires are installed incorrectly?

Glad I could help

BTW, excellent wheel selection and color for AW! I think you're right - once you increase the wheel offset it makes the tire-to-fender gap look much worse than it did with stock wheels but that can be easily fixed...

Thanks....love the dark gray against the AW as well.

I have to say that I am a bit embarrassed re: install. I have put countless wheel/tire combos on my cars and should have known better. Just got them delivered and was in a hurry. Glad I've only put less than 20 miles on them before finding out

Perhaps I'm a bit biased because I have AW and MW but I also love the dark wheel color contrast against the white body color.

No harm, no foul. Just be glad you didn't have them installed last Wed-Thurs when we had the torrential rain! However, with the full tread depth I'm pretty sure you would've been ok - I've been caught out on Michelin PSCs during a track event at VIR and I survived!

I've been to Summit Point with my client who tracks an E36 M3 there (as well as VIR) and I can certainly see how that can happen very easily at the track.

...off to the garage to make the change.

The ZCP offsets are 19X9 ET31 and 19X10 ET25,GTS will be the same just black.
