I just went through a bit of a hassle with D&D Motorsport about their k frame so I wouldn't order from them right now, if ever. But a k frame can shave about 100#'s off the front end of a
Stang. Griggs and Kenny Brown probably have the best ones out there. They redesign the suspension geometry by adding 1" to the wheel base and they allow for the car to be dropped an extra 1" without serious consequences. I think they aren't hipe cuz I've read from others about the before and after and they all say it's night and day difference. My take is to spend the $$ and go with one of the above. Plus you'll need to go with 4-bolt cc plates if you go with a coil over kit.
