Comprehensive weight savings list for the V6 (LLT)

The 18" TSW and Forgestar F14's are about 18.5 pounds a piece, which is a 14.4 lb weight savings per wheel. So a total of 57.6 pounds of unsprung rotational mass (assuming you go with the same tires) would be worth ~570 lbs of weight loss? That seems unreal, but if that number is correct you'd definitely feel it I would think.

I have heard that rotational mass is somewhere bewteen 4 and 10 lbs stationary mass. This would put that number for your weight drop on the wheels between 230 to 580 lbs. Probably much closer to the lower end. For sure something you will notice when accelerating.

I just read recently, that the 1lb of rotating mass equalling 10lbs of sprung mass is not the norm. Possible yes, but not the norm. I can't remember the explaination given unfortunently.

In our case, its probably on the low end, and so losing 57lbs of unsprung weight is probably more like 2 - 4 times that amount in sprung weight, so 100 - 200 lbs I'd guess.

Even so, that is a FANTASTIC weight loss to unsprung weight. I'd be extremely happy.

dropping the steelies is one of my favorite mods lol, looks so much better and the 44 lbs i dropped made a big difference in driving feel. car feels more nimble and spins the tires easier now.

Amen! Also KMP post on weight is a great post to show how weight affects on dyno. Also overall tire diameter as stated in poor man gear change will add as well. This may have been already stated but I got behind on this thread and didn't read all.

rs headlights weigh 10lbs each

weighed and took out the washer fluid resivor today it weighed 12lbs filled!

To be able to calculate the equivalent chassis weight of a specific value of Rotational Mass, you will need to compute the following:

1. The car's weight
2. The Time it takes to reach a certain speed ( 0-60mph)

Camaro V6 2LT (3751 lbs) (0-60mph: 6s)
40 lbs of (Wheel/Tire saving) = 255 lbs of chassis weight

Camaro V8 2SS (3935 lbs) (0-60mph: 4.7s)
40 lbs of (Wheel/Tire saving) = 233 lbs of chassis weight

Hope this helps

Nobody knows the weight of the v6 rotors?

I wish someone did, because I am trying to find some light weight drilled/slotted rotors or depending how how drastic the weight diff is between the ss brake system, upgrading.

The forum search button is our FRIEND.

Type in rotor weight. two finds come up

http://www.camaro5.com/forums/showth...t=rotor+weight

See post 2 and 3 for SS rear rotor weight and V6 rear rotor weight.

SS is 24 lbs.

V6 is 17.3 lbs.

See post 5 for front rotor weight for both.

SS front rotor: 25.2 lbs.

V-6 front rotor: 22.0 lbs.

Hope this helps you guys out.

O yea I remember coming across that thread a like a couple months ago but forgot about it . Thanks! ...now its time to do some searching seeing if I can find some lighter aftermarket rotors.

Let us know what you come accross, rotors and pads are on my list to replace in the next 12 months. especially if lighter.

Same here, and will do
