Just went to order Elbac Sport Springs for 11 Gt converible with Panhard bar and salesperson said dont do without kit as will not work. Looking for imput as also wanted to do engine mods.

 

Have put on the Eibach pro style springs without a problem. One suggestion. Put on the caster/camber plate as you go along instead of coming back and doing it later. These springs will effect your camber and you will not be able to adjust it without the plate. If you don't you will wear out front tires in a hurry.

 

Typical sales person. Trying to get you a whole kit in stead of what you want. While kits are better (all parts work better together and save you money over buying them separately) it is up to you what you want to do. A suggestion for your car (as a Convertible, but a good one for all Mustangs) is to get a set of subframe connectors before you get to far int mods to performance. You don't want to twist stress cracks into your unibody on a vert!
