Just installed Dinan Front Stut Braces on my Est. Blue '99 M coupe. Installation was not too bad, but did have to adjust hood latch mech. so as to avoid denting it when closing. To be honest don't feel much of a difference in cornering around the city but have noticed a lot of the noises up front have dissappeared. I am looking into the "Shark" injector as an engine upgrade for the the M coupe. Have read some reviews that call it more "functional" for city driving. Any opinions?
