My son and I are working on a new project. Very cool to hang out with my teenage son and a buddy from high school. We have some very good kids who will be coming behind us and keep the racing sport alive. The boys have some ideas on an engine that we are going to try and (while money is very tight) I don't mind spending a little money on something that may or may not work, knowing that we spent some good quality time together. It so cool that my teenage boys still want to hang out with Pop and there friends do too. ANywho, I /we have some questions.
We were discussing the merits of the mid/late 70's rear spoiler (Camaro, Monza, Firebird, etc.).
Looks like they would reduce rear lift and increase drag. Is this correct?
How much Cd points do they add?
Is there a speed below where they are not worth adding?
Is there a speed above which they are worth adding?
