By now everybody and his brother has seen Colonel's weight reduction thread over at LS1Tech. Mike's (94Bird's) thread over at LS1.com was a big hit also.

In another week or two I'll be doing a bunch of weight reduction to the car and getting it ready for a 6-point rollbar over the summer. So I decided to pull up Mike's thread and assemble the several posts into a checklist to use on my own car. It's a great list of weight reduction specific for cars that still have to be able to turn (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

Mike's list (as well as Colonel's) can be accessed as a formatted Excel spreadsheet here.

Hey, good summary. I do have some new parts to add to your list. Yours is not in the same order as the spreadsheet I've been maintaining, but I didn't see these on your list:

BTW, negative weights indicate heavier parts than stock . . .

Grant steering wheel -> 2.5 lbs. (stock = 4.5 lbs. including SIR coil, not including airbag and radio controls)
LS1 driveshaft -> 5.5 lbs. (stock LT1 steel = 17 lbs.)
SLP headers -> 12 lbs.
Global West front control arms -> -2 lbs. (stock are 4 lbs. and GW= 5 lbs. each)
Brad Blaine Carbon Fiber Targa Top -> (it weighs 3 lbs. 4 oz. and the stock t-tops are 26 lbs. I will lose more than this once I remove a few of the supporting structures for the t-tops)
C5 brakes -> 7 lbs. (less than LT1 stock)

I'm going to think long and hard about cutting my exhaust system short and dumping it in front of the rear wheels. That will likely save 20 lbs. or so since I'll also use a smaller muffler.

We had some more discussions on this board when it first started up on this thread:

Also, switching from stock front springs to GC coilovers saved me about 12 lbs. in total IIRC, but for some reason I can't seem to find that sheet I wrote that down on anymore. That was before I was maintaining the spreadsheet. You could save even more if you went with shorter springs. Jon A probably remembers the lengths better than me, but I believe I currently have 10" springs on there and 8" will work quite nicely.
