I'd really like to see what my car's weight will be down to once I dump the A/C. It already came with no rear wiper, no linkage or anything to the rear hatch, manual locks, and manual steering. Took out that crappy foam from under the hood too.

That's the one. I just got back from some errands after work. So I won't e-mail it out, bc you can all just grab it from the above link.
I couldn't remember where I got it from...

Great list so far guys!

Does anyone here have any experience with GT Racing's parts?

I've got a bunch of them on my street car:

Fuchs weigh ~15-16 lbs each if I recall. That's why I have trouble thinking about getting rid of 'em (for 17" wheels & big reds) - they're so light.

Danno

Yeah, my 951 16x7/8" Fuchs weighed 15.5/16.5 lbs each; a little lighter than the 911 Fuchs of the same size. Not gonna find a better wheel really. I had 17" Techno Twist copies and they were 25 lbs each! Not sure where GT-racing gets their before weights, but they all tend to be on the heavy side... by a lot! My hood weighed about 45-lbs and when you get the GT-racing CF or fibreglass hood, you still have to transfer the stock reinforcements underneath and the hood-shocks over. So the actual savings isn't as much as they claim. The fit and finish is also horrible! Nothing like the CF stuff you can get for the Mustangs and Honduhs. Plan on at least 1-3 hours each on sanding and finishing the GT-racing panels.

Well, they seem to sell 2 versions. One bare hood requiring the support transferred over (450), or a complete ready to bolt on hood (650).

I don't know...if I had the money (which I don't), I wouldn't care too much about finish if I knew it was gonna save me a minimum of 25 lbs. I've never been a big cosmetic guy.

But it's something to think about for the future.

I'm sure if I could get enough buyers, I could get C/F hoods made for the same cost or maybe less. I did that on my last car...just had a 1-off done. And it was cheaper than Fiber Images wanted for the same application...by some $225 bucks!

Don't forget the rubber sound deadner inside the fenders. There must be 30+ pounds of this stuff! How about those big plastic inner fender shields? Do you need those? How about the front tie down hooks? Think about weight distribution as well. Maybe relocate the battery further rearward and lower (perhaps behind where the passenger's seat would normally be).

If you are serious - strip the interior and decide what is neccessary and what can go. Then get the car off the ground and start unbolting everything else that comes off. If you need to keep it - see if it can be made from a lighter, alternate material.

I went through such an exercise about 11 years ago when I built my autocross racer. I looked through the "Prepared" class rules to see what was legal. I started with a "Production" class rally car that weighed about 2650 lbs. When I was done the car weighed 1550! I had to put back 130 lbs to make it legal for the size engine I run. It is a fun an interesting exercise.

Start with a 924S..

Lexan windows. Oh, and How do you get underbody coating OFF??!!

Scott at Team Harco

I used a straight razor (the kind you push straight ahead - not cut like a knife). Be sure to have lots of blades on hand as you will likely snap a few.

This is not a fun job - but there is a lot of weight savings to be had for the dedicated and patient.
