what is the biggest wheel I can get on my mk3? thanks

7”-15 are a good fit but you can go up to 8/17” I have had both on my capris
But the 17” are a harder ride

Depends on tyre size, and offset. Do you want big diameter, or width? 17 is about the biggest diameter you can get without affecting the rolling radius too much (and therefore gearing/final drive + speedo). Width, 8" is ok at the front, you can get 10" under the rear with the right offset - and as long as axle x frame kit/exhaust ect doesn't get in the way.

Edit: Have you played with:
