Has anybody got in ideas for safe weight reduction on a 2011 SS L99? I hear the stock rims are heavy, but wondering if there are any chassis mods that can or have been done?

You can pull the seats, carpet, speakers headliner and things like that but basically ruin the car. I'd rather add power than subtract weight.

There's more then is listed there, but... it covers a lot of it.


Tubular front/rear supports...
Lightweight exhaust (thin wall steel) with bullets/dumps at axle
Light wheels/tires
No airbags
Trimmed metal and removed most sound deadening behind dash
Kirkeys
Trimmed front frame rails
Removed battery post bracket and fuse box bracket (fuse box to passenger cowl area)
braille battery
bmr drag brake kit
no front swaybar
no oil cooler
removed evap charcoal box + evap line
no heat shields
no parking brake
glass hood
cowl steel removed/trimmed to windshield, except for a/c area on passenger side (the black box) including wipers/motor/all that crap
engine harness trimmed to necessary components
removed all foam blocks behind interior panels
lightweight aluminum tube CAI with plastic CAI box
aluminum lug nuts
1pc DS
rear seat back
all factory belts removed (harnesses in front)
airbag modules

I'm sure there's more, I just cant think of it all.

Still to do:
Remove entire interior harness and trim all airbag and nonessential crap out of it
Speedglass windshield/rear window
Lithium Battery ($$$/lb)
Tubular cradles F/R (big)
Minitub rear tire area+ remove battery well and relocate battery to passenger side (est. 45 lbs savings)
Remove front frame rails forward of shock towers and tie rollbar into frame through firewall, and make a tubular radiator brace across the assy (another 25+ pounds est)
Front coil-overs (strange DAs are cheap)
Some sort of smaller brake kit in the front, since the stock brakes are overkill large and ridiculously heavy.
Remove ABS module+line (12 lbs)
Remove all sound deadening behind dash and carpet (time/lazy)

my car still has a stereo, full interior, panels, air conditioning, and the weight penalty of a roll bar, 4l80, and an aluminum intake, and is still under 3400 pounds. its doable.

Interior parts are one, especially if it's a 2SS/RS model.

I've done 18's front and back, longtubes, cats, stock mid pipe, Moroso Spiral flow mufflers, stall, !engine cover, and I take the stuff out of the trunk for racing. I also have a battery to install that's 15 lbs. I should be 3900 next time out.

im on my way to see what i can do. ive cut the fuse box , terminal, front and rear crash bars . + the norm stuff. but gonna wait till winter and go thur and do alot more and trim alot off . take all the sound deading stuff out and go with something much lighter if anything. just trash alot of stuff that u wont never know.

what battery u guys running, is the braille 15 doable .

I have the Braille 17lbs and there is absolutly zero problem with it. Voltage is always perfect. Exhaust is a good weight reduction too. Of course wheels and seats too, but wheels setup are expensive on 5th gen..

i cut my wheel well out and , put the 17 braille in behind the wheel. i took the exhaust off till about half way but will change that in and out and 20 lb seats. thats a good start for now.

I'd image you could save weight on the factory wheels too. My car came with a set of TSW's on it & supposedly they are a bit lighter than the factory wheels. I'd definitely remove the engine cover, get a light weight (carbon fiber?) cold air indcution. I have CAI Inc. cold air intake aand I swear the thing is as light weight as can be. You may want to see if there's any lighter weight hoods you could install, something that enhances the appearance & reduces weight at the same time. You could probably do the same with the rear spoiler or just do a rear spoiler delete. As others have have said headers & exhaust system will probably help save some. Wish you luck into getting the car where you want it to be.

!engine cover, !trunk stuff on race day, 18's front and back, a lot of exhaust work, converter, undrive pulley, only weight I added was the trans cooler.
