I have a set sitting on the bench, lol. I will put them in before spring, barring anymore house calamities.
By all accounts they work great. Basically a Herb Adams design. I know when Mary Pozzi put them in her car she said they made a very noticable difference autocrossing. As an 8 time SCCCA national champion (or something along those lines) she'd know, lol. Do it. Tell Dave (Pro-Touring F-Body) I said hello.
Do you have sub frame connectors yet? What kind of body bushings are you using?
