Total Weight of Corsa and 19\" Purners

Since I had some time before installing my new wheels/tires and Corsa exhaust with R/T HiFlow Cats, I decided to weigh everything so I could compare it to the factory items. Here is what I can up with:

3" Corsa Stainless Steel Catback Exhaust: 67 lbs
Factory Catback Exhaust: 48 lbs
Net Gain in Weight: 19 lbs

Random Tech Ceramic HiFlow Cats: 12 lbs
Factory Cats: 21 lbs
Net Loss in Weight: 9 lbs

Total Exhaust Weight Gain: +10 lbs

Rear 19x13 Purners with 345/30s: 64 lbs
Rear 18x13 Factory: 67 lbs
Net Loss in Weight: (3 lbs x 2 = 6 lbs)

Front 19x10 Purners with 285/30s: 56 lbs
Front 18x10 Factory: 58 lbs
Net Loss in Weight: (2 lbs x 2 = 4 lbs)

Total Wheel/Tire Weight Loss: -10 lbs

Overall Total Weight Change: 0 lbs

Great info! I thought Corsa would be lighter. Only comment I have is that rotational weight reduction (wheels) probably has more impact on overall performance of the car than reduction of sprung weight.

What kind of factory wheels did you have?

I would expect the Purners at 21 lbs rear and 19 front to be about 10 lbs lighter per wheel than the factory rims.

Thanks for the info! So much for saving alot of weight with wheels!

I think lighter wheels are offset by heavier tires - I presume these are wider than stock.

Russ,

My car had the factory wheels/tires that came on a 2000 GTS. (Rear: 335/30/18 and Front: 275/35/18) I weighed both sets as a complete wheel/tire with a scale that was good to a 1/2 lb. I talked to the guy from CCW and he said that since the rubber was bigger, the larger tires would offset some of the weight. I was surprised at the small amount of difference myself, so I felt others would like to hear the actual numbers from my experience.

The car has more off the line, which may be due somewhat to the rotational weight issue, but I also changed my gear to a 3.55:1 at the same time. With the large diameter tires, the effective gear ratio is right at 3.33:1.
