So that got me thinking. How light could one get an f-body. According to the 9.5:1 weight to power ratio 200rwhp car weight 1900 lbs. It could be quite easy to turn, brake ect. that little weight on 275 tires and 14" willwood rotors. Shouldn't it? Can one get an f-body under 2000lbs?

AI rules are here:

Anything that doesn't fall under these rules is subject to the NASA rule book (much larger file):

So, for AI see 6.1. There's no minimum weight for a 4 or 6 cylinder. Many have contemplated a 4 cylinder turbo Fox Mustang. You can get the Fox body pretty light (not sure how light) and the 4 cylinder doesn't weigh much. That doesn't help the Camaro crowd of course.

I have no idea the lowest a 4th gen could get. Ours is around 3000 empty. There's probably another 100 pounds in there, but I don't see much more than that. Maybe 2800 pounds as the lowest weight? But I'm just making that up based on my experience. I could be wrong.

Edit - So Al beat me to it. 2400 pounds? That's crazy! But I'd love to see it.

The fox chassis can be made very light, but the turbo 4 is not so much so. The Iron block SBC’s are a good 200# heavier then a plain old 5.0, those things are small and light, and the turbo four was a special version of the 2.3 cast in Lima that weighted within a few lbs of the 5.0.

I’ve seen V8 fox chassis in stripped down road race trim that were around 2650lbs with driver, so I wouldn’t be surprised to see a turbo 4 in the 2500-2600lb range.
