I know there is millions of threads around tyre/wheel combo but I don't seem to be able to find a definitive answer for me.

I am thinking of going 265 30 front and 305 25 at the back but I can see straight away that front will have to get around 7-10mm spacer because of the brake caliper.
I don't expect the rear to be a big problem in terms of caliper clearance but maybe someone could let me know if I would be better of running 295 or 305 with this rim setup and KW HAS on as well.
"Will they fit" says using 305 will up a little tyre height (6mm) which is great because I worry a little about potholes and the condition of UK roads all together.

Don't want to play with camber or see any rubbing.

Any thoughts?


Thanks
Cannot comment on the 21" wheel set up but am running the KW HAS kit with 305 MP4s on the rear with 10mm spacers as well and there is/was some moderate rub on the wheel liner carpet. Had my performance shop shave a bit and now it sits tucked with no rub on dips/pot holes. One thing I have to be careful about now is front splitter on dips.
