GRC Performance

i would NOT go there. do a search here for grc and you'll see why. i know some of their past customers as well and they are very unhappy with them.

xmp is only 4 miles to the west and they do excellent work.

what type of suspension are you thinking of going with??
 
xmp.
top quality.
I have used every mustang shop over the past 10 years in o.c. and they are the on;ly ones that have ford support and actually know how suspension is supposed to work. GRC did not rub me right .
