Steering wheel turns too much

The car is a Shelby Cobra kit car; with the steering rack and suspension from an '89 5.0 Mustang

I've got a slight little problem...its not huge but it's bugging me.
my steering wheel turns too much to the point where the inner ridge of my rim is rubbing my lower control arm...is there any way that I, or an alignment shop can somehow adjust the stops so that it doesn't go that far?....

thanks all

 

if all front end parts are in good condition im sure that a stop could be added or the existing one modified to prevent the rim from hitting however you may have a hard time finding a shop that would do the modifications.
the real problem is probably the rims as they likely have to much backspacing for the vehicle it is mounted on.

 

You're rack should not be too much for the front suspension (since both are '80s Mustang) and your kit looks like it's quality
I don't remember any specs on the rims though
That would be a common problem for guys that put the wrong backspacing on their 'Stangs

If the tire/wheel is too big that usually ends up with the rubber rubbing the upper, so I don't think it's any upsizing you did
But what size wheel/tire did you go with?

 

Found your pics
That's a modified Fox front suspension, or more like an aftermarket drop-in that fits a Fox
Love the coil overs!
Looks like you have even more room than a Mustang would
I've dealt with these racks, you really shouldn't be rubbing your rims against those lowers

I found your wheel guys but didn't have time to check which ones you have,or any specs
I'll try later

I don't remember the backspacing you need off-hand, but I'll take a look around tonight

EDIT:
Assuming a tire width of 255mm
5.75" backspacing on a 10" wheel
5.50 on 9.5
5.25 on 9
4.75 on 8
or an offset of 3/4" negative

 

If it is only doing it on one side you might want to check that you have the tierod ends adjusted equally.if not you will have more toe out on one side than the other. This is easy to check. Look to see that there is equal amounts of thread on both tie rods.
