[QUOTE="1995COBRA-R, post: 10513785, member: 9515"] I'd try that first. Simply, a car that suffers from bump steer finds the front suspension dialing in slight unwanted steering when going over a bump. ;-) It can be a little unnerving at Sebring when going thru T-1 at 100+ Mph. I doubt that you will experience it on a street car with just a small amount of lowering. Did Shelby install suspension bushings with a higher durometer index (more rigid)? Mustang GT's come with OEM "softer" bushings and would be replaced in a race car with rigid bushings. The more rigid the bushings; the more it pronounces any bump steer. Polyurethane bushings are often used to replace "rubber" bushings. As mentioned, you must find a very knowledgeable guy (probably one that works in a race shop) to set it up properly. You have to go back and forth between the two sides numerous time to get it right. The labor rate could run $500+. IMO, the S197 cars have much more complicated suspensions (that's why they work so well) than the SN95s. Then Ford has made adjustments during its current production cycle. There is a lot of new engineering stuff going on underneath. Be careful. BTW, It is a beautiful Snake. Robert, You didn't ask this question, but I'll give you my opinion, anyway. :-D I'd leave it just as it sits. :-D My theory: Shelby has already lowered it once. They have probably already lowered it just enough to keep it compliant with the suspension components. :shrug: After you pass this line, you will probably need camber/caster plates (they install under the shock tower; the SN95 C/C plates install easily above the shock towers) to keep from wearing out the front tires. You may need new coilovers (shocks) because they may not work well after a car is lowered beyond a certain point. And don't get me started on the five different steering calibrations on the S197. ;-) Just saying: My suspension file on my computer is two paragraphs for a 1965/1966 car. It's a page and a half on the SN95. It's 5 pages and growing on a S197. [/QUOTE]
