I did the LW battery thing, to be honest, it's a pita IMO. They really don't like cold weather at all, at least mine didn't If I tried to start my car when it was cold, say 35 or colder, forget it that thing was dead. Granted this is a high comp 402, but still.

I have since put a full size battery in the back in a moroso sealed box so I didn't have to mess with a bulkhead, and every tech guy in the world knows the blue moroso box so that should never be an issue as well.

Plus then you can add the shutoff, one less thing to worry about with tech.... and when people see a car on the street with one of those, they know it's not a joke

How much weight are you looking to take off and is this your track only car?

^ Yes, pretty much going into that direction. I'm not in a hurry, but slowly and surely. So far, front/rear bumper support, front swaybar, all seats except driver, carpeting, soundsystem(radio,speakers),power steering,a/c, compressor, and looking for more weight to remove.
Thanks.

Cut out the extra stuff on the shock towers and make a new radiator support, then put mini tubs and trim the extra metal around the rear fenders and bumper, that's an easy 150 pounds or more.

Careful listening to ragen, this guy likes to cut **** up LOL.

You can get one of these cars with a 10 pt cage, and an iron block lsx down to 3000 lbs, it's not easy, but it can be done, without cutting too much of it up.

Door bars, wiring, all the tubular stuff, drag brakes and manual master is huge, that's like 120 lbs off the car. Spool saves 15 lbs of rotating weight, drag rims are 100 lbs lighter then stock rims, I found out moroso ds-2 front tires are 14 lbs per tire lighter then m/t sportsman fronts, that's 28 lbs off the front that's also rotating/unsprung weight. Fab 9 inch rear narrowed about 5 inches per side and a 15x10 inch rim with a 4 inch backspacing is a good bit lighter as well.

If you have the $ and time, you can do alot to lighten these cars up.

Yup. I couldn't believe it myself. My fab guy swapped the tires while the car was in for the exhaust, he has a local guy with a good rim machine that works well on LW drag rims ( doesn't bend them ) and he put them on his scale. And this is the difference from teh 4 ply ones, I wasn't running the 8 ply ones!

14 lbs per tire lighter, and I can tell you, just picking the front rims up now with the moroso tires on there, they feel a ton lighter.

I have the old tires here, and when I picked them up, I think the tire alone weigh's more then the moroso tire and the rim together do.

I bet just doing these, the drag brakes and the spool I lost a good 75 lbs of ROTATING weight. They say 33 lbs of rotating weight is equivalant to 100 lbs of regular sprung weight, I don't recall where I read that but those #'s stick in my head for some reason.

Should be intresting to see what the results are.

I thought it was about 100 pounds of static weight was a tenth in the slower cars and 50 pounds of rotational mass was worth a tenth. Not sure either where I heard it either was a long time ago.

True you don't have to cut a car to lighten it, but you'll run out of stuff to remove pretty quick. I'm looking to get mine under 3,000 race weight (with me) with a tall deck BBC and TH400.

Moroso DS2 fronts are something to look at, since I 'm running your typical 165r metric radials, which I'm sure are heavier than what you guys have previously mentioned here.

I don't think I'll be going that extreme into cutting the car that much. Thanks for the tips.

If I did more weight reduction with the Camaro, I'd do front drag brakes for sure. It's 3100 w/o driver with stock brakes, k, and u and lower control arms.

PSJ, I can't believe Pinkenstein still has stock k,u/l control arms. And most of your launches are in the air, amazing!

Been up at GLD lately?

I still have stock k member and a arms on my car, btu I did put a motor plate on it so the stands and motor mounts are gone,a nd I know the plate is way lighter then they are (did this in anticipation of purchasing a burkhart k member setup)

tektrans I can't believe you're running the 8 ply, christ that's like 50 lbs of rotating weight tha can go away. There's your 9.30, it's a tire swap away LOL


I know the moroso ds1's are 1lb a tire lighter then et front's, we weigh'd one of those too.
