Suspension suggestions?

Bilsteins.

Go to Ebay and type in "mustang shocks"...you can find mucho good deals on all kinds of S/S....Tokico's/Mach1s/Bullits and even Bilstiens...I was searching myself last night...

If you don't want to spend a lot then definitely don't get Bilsteins. They are the best but they are also the most expensive. They have a lifetime warranty, but that won't do you a lot of good if you only plan to keep the car a few more years.

I believe KYB shocks and struts are cheaper than Tokico and Koni but I've heard mixed opinions on them. Personally, I'd shoot for some Tokicos. They really aren't that expensive if you look around. I got a set of very low mileage Bullitt (Tokico) shocks and struts for $100 shipped on the classifieds. If you shop around, you can find good deals on Bullitt or Mach 1 shocks and struts, and those are all made by Tokico.

I got my bilsteins from bimmerparts.com (a suggestion from another member) which was the cheapest I found them. They are great!!!
