255/35 & 285/35 with spacers and h&r supersports

[MTW1989]

I have just ordered MPS cups 2's to replace the stock MPSS.

the only size i could get for rear was 285/35/19

so I will be running 255/35/19 front 285/35/19 rear, on stock wheels

does anyone run this setup? from my calculations the size difference front to rear should not cause problems.

but im running 12mm spacers on the rear currently (15mm front) and H&R supersport springs, so im trying to figure out if ill have any rubbing issues?

i could drop down to a 10mm spacer if needs be.

just wanted to see if anyone else has run this setup and what has it been like? upset the car in any way? lowered or not.

thanks
