How To Get To 1800 lbs, How to Lighten My Racecar Options

[motorvated]

Just put in my fresh 2.0 liter motor, replacing my stock 1.8 liter and it is definitely a much stronger motor and my lap times have gone down. I’m still a little slower than I would like to be, but driver skill aside, I’m wondering how best to shave some weight from the car. It already has fiberglass Chalon fenders and bumpers on it, but stock hood, trunk, and door skins. One racing seat, no top, fake Fuchs, header exhaust, fuel cell, 6-point cage. Don’t know what it weighs right now, but I’m sure it’s not anywhere near 1800 lbs. So where do people find the weight savings? My door panels don’t weigh very much, and I can remove them and the door glass too. I prefer to keep the stock windshield but could remove the rear window if that would help aerodynamically but that may be unsafe from a fire spread perspective. Could remove headlight assemblies and install fiberglass hood and trunk. I usually run without the engine cover. Any thoughts on this?

Bumpers are heavy.. especially those rear bumperettes I see. If they are the later wide ones, that could be 20lbs right there.
Look at everything in/on the car and ask yourself two questions:

1) Do the rules require it?
2) does having it make me faster?

And if the answer is no, remove it!

Roof off, might not be helping.. Sure its lighter, but there might be an aero benefit to running it. Sure its 8-10lbs.. but if running it adds a few mph on the longer straights, it might be worth it.

Get it on a scale (local waste transfer near you? local club scales? SCCA scales?) and then just start removing as the rules allow!
