Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I am in the process of installing coilovers and poly bushings on my 996 C2. I bought a Rennline bump steer tie rod kit but now I am wondering if I need it. The car originally had USA M030 suspension on it. I am only lowering it 1 inch to 2 inches max in the front with the coilovers (don't want to go too low b/c I drive the car to/from the track). Can anyone tell me if it's worth it to bother to install the bump steer tie rods or just keep the stock tie rods going down only 1-2 inches?? Looking at the tower height on the bump steer tie rods it looks like it might be intended for a bigger drop than I am doing. Thanks!!!

You’ll be fine. At I’m at 4.25”F and 5”R and was dang surprised I could get away with stock toe arms and droplinks. As far as front bump steer, below 4 is where it starts to kick in. But a little racing secret is that bump steer is toe out. So it hurts in the rear but actually helps you corner in the front. My PB in my racecar was 3.5”F 4”R. photo604.jpg photo596.jpg

Thanks Slakker that makes sense w/ toe out. I won't be going lower than where you are at.
