nice paint/finish on that P40.

[Johan@WSTO]

20 inch 360 Forged Mesh 10

The front is heavier than the rear.
The front center has more material than the rear center because of the offset.


Front : 20x9J


Rear : 20x10J

This is one of the best threads I seen and Robert thats awesome! I love the dyno one!

You are the man PG.

Yeah, this thread is amazing. This info would be great on all car forums, not just this one. Everyone is always asking wheel weights questions, now finally some concrete answers.

Those Mesh ten's look great but seem, heavy compared to the rest of the bunch don't they?

interesting thread! I was just messing around with some wheels yesterday.

I weighed my factory 18s with PS2s as well as my D-force 18x10s with PS2s

My factory wheels/tires weighed:

Front 47.8 lbs 75% tread remaining
Rear 49.7 lbs 20% tread remaining

D-force LTW5 18x10 with brand new PS2s 275/35/18
45.2 lbs

Here are my pics- Somehow the pics of my stock wheels have magically disappeared so...

Front Weight: Dymag Carbon-2 19x9

Rear Weight: Dymag Carbon-2 19x11

Just for comparison sake: G-Power Silverstone Diamond 20x8.5


G-Power Silverstone Diamond 20x10

I wonder how much those run for...?

that's pretty lightweight! i'm surprised

WOW!! That is very light. I never would have expected that.

Anyone know how much the stock 18's weigh?

How much do those weight in at for an 18x9.5?

The Volk G2's aren't built in any 18" fitments. Not yet anyway...

[goodoleme]

Can you post the weight of the oem 18s and 19s?

Umm....only 1-1.5lbs difference between the Dymag and the Volk CE28.

Yes, but it's not that simple...

Yes the overall weights are close...but the effective weights are much different.

Let me explain...

The Dymag wheel has less effective weight in regards to performance, because it's Carbon Fiber outer barrel is located at the farthest point away from the center hub. That CF barrel is much lighter than that of the Volk CE28N. (i.e. the Dymag's outer barrel has less MASS)

Since a majority of the Dymags overall weight is contained in the Magnesium/Aluminum center spoke portion of the wheel, it's moment of inertia is much lower than that of the CE28N. (which is made of 6061-T6 Aluminum Alloy)

Since the Dry Carbon Fiber outer barrel on the Dymag wheel is much lighter in overall weight, it requires less energy to do the same amount of work. Which means it's easier to get the wheel to spin from a dead stop. It also improves the transitional performance during frequent accelerating and decelerating. (by reducing the load on the engine to spin up the wheel again after slowing down)

The Dymag's are a stone cold killer on the track...

Since the Dymag wheel has the lightest part of it's overall weight at the farthest point form the center bore, it's real world performance is superior to that of the CE28N.

FYI: The closer you get to the center bore, the less impact the weight will have on your overall performance. (physics 101)

But be advised...this 'advantage' in wheel technology comes at a staggering cost!

I question the amount of the advantage of a lighter rim area. The rims moment arm is less than one foot (~9.5" for a 19") Even if you have a 2 lb lighter rim, it seems that would mean 9.5/12 ft x 2 lb x 2 driven wheels = 3+ lb ft of force difference necessary to accelerate the wheels, which is only around 1% of the available torque.

Is there a flaw in my logic? Also, the distribution of the weight makes little difference to suspension action, the other key advantage to lighter wheels.
