Max Tyre Sizes C63S Coupe
I thought the rear rims were 10” they are not they are 10.5” . These are the specs from MB. Clearly traction is the biggest issue, so I could fit short life race spec tyres like Toyo’s R888’s
Need some help with this please.
F:255/35R19 on 9.0Jx19ET25 does this mean we could fit 265 or 275’s?
R:285/30R20 on10.5Jx20ET57 does this mean we could fit 305 or 315’s?

315 is hard even with an aftermarket wheel with the right off set.
What are you doing to the car in terms of the build?
Specs are:
Akrapovic full Ti system, Armytrix 200 cell downpipes, upgraded Turbo's both inlet and exhaust impellers have been increased as well as bearings etc etc, in other words bigger turbo's in the stock housing - just.
ECU programming to suit our premium fuel, 98 Octane. KW modified V3/4 kit to allow much lower drop than the stock KW drop of 30mm. BMC filters. Renntech BOV's and Tie Rod's. Light weight Lithium battery.
Mode Carbon, front grill, and other parts not listed yet.
Large and high Rear wing, think Black series.
Have looked at new rims, I like the standard ED1 RXC more than anything I have found aftermarket at this stage.
Numerous other small tweaks, spacers etc.
Timing: About half way through, main issue is freight timing delays. Should be finished end of April.
Sorry for the delay in responding, wanted to lock down the spec first.
