Since I'm a convertible I wont be doing any track racing anyway. This was mostly a comfort decision. I drive my car way too much for it to ride like a truck anymore. lol

The 3 link from griggs/mm is great, however if I were to build another mustang with a SRA I'd be going with a watts link and evm tri link.

Since my cars in the garage torn apart, I wont feel the benefit or anything till next spring. I'm also a little irritated that I didn't think about the 3.55 gear ratio ahead of time. I'm getting Cushman stage 2.5 blower cams and i need 3.73's minimum. I wounder if it's gonna matter that much?
