Four Link Suspension, how does it work?

Before you ever decide to make any changes Les, you need video of the car from the SIDE. This is so you can see what the suspension is doing at the release of the trans brake. That will help you make decisions on what to change on the 4 link, if anything. This is also important when tuning the shocks as well.
That's a great suggestion. Now, If I can only get the Crew Chief to go to the track with me to make that video. Got a father's day race on Sunday so hopefully she'll come with me. Otherwise I'll have to recruit one of my friends there to do so. The care just feels like it's not 'hitting' on launch like it should and my 60' times are a bit slow from last season. The only real change that would affect performance is I've gone from the tunnel ram/dual carb induction to a single carb. car launches clean and straight just feels soft and I know I shouldn't go just by feel.
