One more question Flyfish, I have a full interior car, with a 2 inch 6 point rollbar, so what would be your guess on the weight of my car? Have you weighed yours? Is it full interior?
The last time I weighed my car was when I live in Colorado… probably about 4 years ago. At that time the car was all steel with a 6 point cage, sub frame connectors, 4 wheel disc brakes. It had a full interior minus front passenger seat, carpet, and wiper motor (driver seat is a fiberglass bucket); it was 3250 with me in it…3075 w/o me. Not sure on the weight of yours, but maybe this will help give you a ball park.
My car is lighter now than it was...I added a fiberglass hood, and I remove the front bumper when I race (33lbs off the nose for the bumper). I’m going to try to do some lightening this winter.
