AJ,
I'm new here but have watched many of your You Tube videos and want to talk with you and get some advice.
I have a 93 Notchback 4 cylinder car I'm currently doing HPDE events in NASA with but I am slowly building toward SCCA Improved Touring B class. We only can do limited modifications and I want to maximize within the rules what I can do.
I have two questions and my first has to do with front plastic fender liners and I feel like question two will tie into these. We can remove the fender liners by rules but I'm wondering if this is a good idea. My thought is that it could either help get rid of or cause even more lift in the front. What is your thoughts and advice?
My second question is what is your advice on the following rule taken from the SCCA rule book for IT:
A front spoiler/air dam is permitted. It shall not protrude beyond the overall outline of the body when viewed from above perpendicular to the ground, or aft of the forward most part of the front fender opening. This body outline does not include bumpers or bumper mounts. The spoiler/air dam shall be mounted to the body, and may extend no higher than four (4) inches above the horizontal centerline of the front wheel hubs. It shall not cover the normal grille opening(s) at the front of the car. Openings are permitted for the purposes of ducting air to the brakes, cooler, and radiator. Dealer installed or limited production front/rear spoilers/air dams/wings are prohibited. The spoiler shall have no support or reinforcement extending aft of the forward most part of the front fender wheel opening. NOTE: Integrated bumper assemblies are defined as those designs where an external non-metallic bumper cover completely encloses the primary energy-absorbing bumper and where this cover could be installed in its normal position with the underlying bumper removed. On cars with integrated bumpers, the front spoiler or air dam may be attached to the bumper cover. Where an air dam/spoiler is used, two total openings may be cut in the front valance to allow the passage of up to a three (3) inch diameter duct leading to each front brake/rotor assembly. Where no air dam/spoiler is used, two total openings of a maximum size five (5) inches by seven (7) inches maybe cut in the front valance so that brake ducts can be added with a three (3) inch diameter hose leading to each front brake/rotor assembly.
For question two what would you do to help the car within rules?
