Drilling holes in things is pretty cheap.

I seem to have endless ideas for shedding weight in the back of the local NA N/A track rat, which is currently at something like 1950 lbs without driver, with a full windshield and hard top.

Taking weight out of the front is another issue, once AC and PS are out, I'm at a bit of a loss. Your list is roughly twice what the entire car has cost.
Subframe $850
Control arms $80
Spindles $300
Brakes $450
Fan $40
Intake $100

Your whole car cost $920? I bet it's fast!

I'm guessing he was figuring the same price for the spindles that I was which had a 1 to the left of the 3.

It is fun for me to see what I can modify to reduce weight, and the process can be quite addictive. If you get bit by the bug, it starts to get expensive once you move past the removal and modify existing parts stage.

The results are fun, fun, fun.
Like I said.

Original build thread. However, it has evolved a bit since then.

Don't know. Seems like you have something else to say beyond asking that question.

I was just wondering because it seems to be the trend in XP. Us "limited" SSM guys don't get to do crazy things like that!

If I recall, the windshield and glass is quoted at around 40 lbs. I cut mine off but didn't have a scale around to check. I would say 40lbs is a fair guess from hold it. Mine was a 90. I know the frame on my buddy's NC was MUCH heavier. Mainly due to the really thick tube added inside the sheet metal folds.

Actually I'm not so sure. Right now, a rear wing limited to rule height with no windshield gets air hitting it after being disrupted by the driver, seats ( two in our case ), and the roll bar.

I've been questioning whether it would be better to run a windshield and use the rule allowance to move the wing up into clean air.

40-45lbs seems right. However, I'm estimating a polycarbonate replacement would give a 20lb savings and allow a more usable rear wing.
