Hi
I have a late 1994 Mk2 with manual steering.
The previous owner did a lot of conversion work on the vehicle such as custom body kit & wheel extenders etc.
bottom line is that the steering @ full lock does not allow enough clearance.
Are there any adjustments that can be made to limit the maximum turning lock, or a part that can be changed on the rack?

There aren't any steering stoppers on the MR2, it's all inside the rack.

What size wheels (including offset), tyre size and wheel extenders are used? And what are the tyres hitting? I assume it's tyres.
These cars were never really designed for big front wheels/tyres.

Thanks for the reply.
unfortunately I cant give you an answer to exact sizes as the car is in a garage miles away.
its got a wide body kit and the wheels are quire large.
they are catching the inner wing on full lock so it would have been simple to just change the stoppers if the MR2 had any.
The guy at the garage said something about having a similar problem with a BMW years ago and got a specialist rack gear part but wasn't sure if there was one for an MR2?

you obviously have an idea which may give me some hope???

I don't know what steering parts are out there to limit lock but maybe just limit how far you turn the wheel when you drive it.
Sorry, hard to picture what you mean by 'inner wing'. I assume it's the part of the body in the footwell of the cabin that catches? Quite normal for even standard cars with tyres of too big diameter or a too large offset. However the TRD 2000GT has some rather large offsets and I wouldn't think it has an issue with that.

As an example a typical tyre on the front is 215/40R17. If you go to a 215/45R17 it will normally rub back there at full lock. Compare your tyre size to these and see what diameter they are.

Thanks for the suggestion.
Yes they are wide wheels.
and your spot on right about me wanting to limit lock how far to turn the wheel.

I spoke with the guy at the garage and discussed putting on slimmer tyres, adjusting the suspension etc but he said it could only possibly help or rectify....

I can't work off if's, buts and maybe's so am desperately looking for a definite way to stop the rubbing tyres without changing the wheels.
steering limit lock seems to be the best avenue to investigate.

You can add a spacer to the rack to limit steering angle. It would need to slip over the rack and secure with a set screw (remove the inner tie rods to install). It's a pretty simple part to make with the right tools, but unfortunately I don't know of any parts that can be purchased to do this. Maybe you can find a shaft collar at a hardware store that is the right diameter?

Great suggestion Alex
I think I understand what you mean for my SW20,
so I can fully picture what you have in mind, could you please explain exactly how to go about it, ie exactly where on the rack to position the spacer, etc?
Thanks.

Here's a picture I stole from google images and did a rough sketch on (shaft collar with set screw)

Normally the travel of the rack is limited by the back of the inner tie rod contacting the rack housing. The goal is to put some sort of spacer in there to limit the motion.

Once we know the size of your wheels, tyres and spacers then we could advise if there could be a solution to adjust that or do what Alex suggests.
