That looks to me like a Super RS4 Rally.
Yup, that's EXACTLY what it is.

Good luck finding parts!
Also, that car has non-adjustable toe links. He can't adjust them. What he needs are the proper toe links for the Super RS4s, or to retrofit it with adjustable turnbuckles and ball cups. Wish I would've had one of those cars so I'd have a giant pile of parts like I do for everything else I've owned so I could help ya out with it.
