Weighed the ole SS today......

Well, I have a 1ss 2010 l99 car. Only weight reductions are removed front and rear crash bumpers, removed engine cover and installed catless longtubes. With a 1/4 tank or fuel, and me in the car it weighed 3900 lbs. With seat removal and trunk carpet and compressor removed that should put me around 3800 w me in it in track form. Last time out was tune only and full weight. Looking to run some 12.3-4' s this time out!

On race days I remove the front passenger seat, rear seat, rear seatbelt bar, and put in a 15lb Braille battery to replace the 44lb stocker. My American racing Torque Thrust wheels 20X8.5 up front and 20X10s in back lose another 35lb or so with stock Perellis in front and Either Nitto NT-05R p315 or MT ET Street IIs p305 in back vs the stock GM SS wheels.

How do you get the crash bumbers off? Did you take any photos of that process?

12.5@115 was my best like this last year. This year Im doing full BMR suspension bushings & sway bars, and a Jannetty Racing posi pumpkin upgrade to 3.91 LPE gears. Last year my best 60' time was 2.01. This year I'm hoping to vastly improve my 60'. As you can see, my trap speed indicates a sucky launch, but lots of HP.

I'm a little foggy about the exact weight savings, but I did weight the mounted stock wheels & tires VS the mounted stock fronts & DRs on the new back wheels. Perhaps is was only about a 25lb weight savings, but I do recall being quite suprised at the loss of lb.

The stock wheels are also cast and have LOTS of material. I was warned by some fellow racers about hubbing the Chinese AR wheels if I got much past my current rwhp.

Rhino79, did you weigh the crash bumbers you removed so I can have an idea about the effort/weight trade off in doing the same thing?

About 50lbs. Just have to remove the front and rear fascia to access them. Took me an hr and a half to do it all.

With a full tank of gas my 2010 SS/RS MT weighs 3,680. With a 1/4 tank of gas and me in it the weight is about 3,795.

If you're interested in weight reduction on a Camaro I've documented everything I've done in my project thread.

http://www.camaro5.com/forums/showthread.php?t=45165

I don't do drags; my car is setup for road course racing but I'm guessing with the mods I have I'd be somewhere in the 11's in the 1/4 mile. My car is N/A but has a cam.

Our Camaro weighs in at just about 4000lbs with half a tank as scaled at the Spectre341 Hill climb. We were definitely one of the heavier of the cars there!

Your car is fully race-ready with rollbar, fire extinguisher and everything isn't it? With all of that in it, 4,000 lbs isn't all that bad for a 5th gen.

I wish I had the cash for some RTS wheels, I think that'd be worth a couple tenths alone. Is like to get it around 3700 with me in it. Some wheels and track setup would be right at that. I just don't want to give up the insulation or any creature comforts......

I'd say a lot more than that. I gained about .783 seconds and 3.876 mph in the 1/4 going from stock to 18s with drag radials with just bolt ons.

Our RingSpec Camaro definitely is not a race car. We had the safety equipment needed for the Spectre, but it's far from a full build. We did Fab up a "Chassis bar" for the interior to allow us to mount harnesses and the fire extinguisher, but those weights are probably offset by the removal in the back seat.

We never really stripped the car, or removed any interior pieces so there is plenty of weight still to be lost. 4000lbs isn't bad for a 5th gen, but compared to a 3300lb ZR1 it's a little porky.

Did someone really call the Camaro ZL1 porky on the Camaro5 website? Allow me to show you porky...

ZR1 MSRP $111,000
ZL1 MSRP $54,995



Ring Times
ZL1 7:41.27
ZR1 Cups 7:19.63
ZR1 OE 7:26.4
  • ZR1 Brakes are good for at least 4 seconds or more
  • 50 HP maybe 1
  • Mero currently has three 3 Fastest Ring times, Link has 1. Is Link as fast as Mero? Hard to say, but he has been in a Vette at the Ring since 2008 and has three of the Fastest Ring Times has to be good for two seconds or more
  • Corvette gets a pass on the GM curb height clearance and wheel arch red zone, so ride height is good for another 3 seconds or more
  • Cup tires are good for 6 seconds or more

Our ZL1 is down 22 seconds to the ZR1 with Cup tires and 14 on production tires. If we even the playing field for the ZL1:

Install Brembo GT-R Brakes
Drop the ZL1 20mm with OEM MRC
Get Mr. Link more seat time in the ZL1 at the Ring

Our ZL1 is right there with the ZR1. Add the Cup tires and we pass the ZL1 on OEM rubber and again are on the tail of the ZR1. No tunes. No driveline modifications. All we added are better brakes and restricted to Corvette only ride height. Mr. Link's seat time is not a mod. The brake upgrade is BIG bucks with a retail of over $20,000. No worries. We have enough cash left over to add a SS nicely equipped 5th Gen Vert to our garage

The 5th Gen Camaro is a very capable chassis, very comfortable to drive, very fun and can be very fast in the right hands...but the fact remains that it isn't a feather weight. That's the only point we are trying to get across.

Since we're now on the subject of the ZL1, check out this video of the ZL1 vs. the Boss 302 Laguna Seca. Despite the weight disadvantage the Camaro still comes out on top thanks to superior handling. Overall weight isn't the end all, be all of performance testing and I don't think anyone is trying to argue that... but the fact remains that compared to other performance cars in it's class it's a little heavy.

Now check out the porky ZL1 handing it to the Boss!

If I can get the SS to 3700lbs dry, I would be happy.

Braille battery
Lightweight wheels
Rear seat delete
Passenger seat delete
Headers and exhaust

I believe our cars are 3850lb wet right? So I can see 3700lb dry with those mods given that gas would be about 75lbs with a full tank and the mods should take care of the other 75lbs.


Is this too optimistic or doable?

Yeah that's doable. The stock SS LS3 weighs 3,860 lbs and that's with a full tank and all fluids. A full tank of gas weighs about 115 lbs.
