You sure have become hardcore with the weight reduction. :D Once you get bigger into adding the HP, your car is going to be a rocket.

Post some pics of the cars current trim. Is the lexan in? What did that run ya'? What does yourcarweigh in at now? I got the bonne fairly light, but we added the cage recently too.

I am just waiting for cooler weather so I can hopefully have a full day of runs in the 11s.


I still need to weigh it, its got to be pretty light now.:eek:

I did the rear windows myself along with the templates for the cuts. $60 in materials.

You just gave me enough info to catch you!
You better hurry up Rob, I'm itching to race this thing...

Well I ran [email protected] in cold weather with only the bumper supports/rear seats/rear carpeting/trunk carpeting/rear door panels/catback removed.

Since then I have taken out a few hundred more lbs, so I am pretty sure it will run in the 11s consistantly with a 1.9 or better 60'

I dont know with the 11.9 if I had all the weight back in the car I would guess 12.1-12.2. What is it every 100lbs = .1 and 1mph roughly?
