Unless you have 205 series golf cart tires it should not rub.

It's def 10" runs I just can't remember the tire width. I'll post pics tonight. 

Assuming you have 13 inch tires on 7 inch rims if you've got a Minitec front end with coilovers. Call BJ at Mintec and ask him for the front settings. With that setup, you might just have to put up with the rubbing. My solution? Don't turn the wheel full lock when turning.

throw on some pics - pictures help fix the issue

I don't remember the tire size maybe a 145 I want to say on a 10" rim. Forgot to say it's a Minitec frame. I seem to be the only one having this problem, haven't found anyone online or at Minitec to say this was a big hurdle for them. My only guess now is its too low. As it sits, I have about 7-3/4" clearance. I have coil overs in the front so easy enough to raise the front but want it to sit level. 

What size tires are you running, even with bad castor they should not hit. If you are running the correct size tires you can install rack limiters as used on the big wheeled MPI's but it will enlarge the turning circle. Stock rears are not adjustable, if you want adjustment you need to buy a set of Hi Lo's or you can seperate the trumpet from the knuckle and use a 3/16" washer in between to raise the height some.

My car is finally about ready for the road. Having a heck of a time adjusting castor and keeping the front wheels from hitting fender when turning. It was suggested my ride height might be too low. I have the rubber bumpers in the back. Are those height adjustable?  Sorry, first Mini and not seeing if it's possible.
