Just to make sure everyone is straight on 18 vs 19":
OZ makes the 5 bolt Allegerita, and CL Challenge in 18" .
They make 5 bolt and CL Ultraleggera and forged Superforgiata in 19".

They are super light. Put a stock wheel on a postal scale and you'll be shocked.
There are very few wheels that legitimately get under 20 lbs on the front axle.
We once measured the Carbon Dymags, and found them to be heavier (2 lbs per corner) than a set of Magnesium BBS wheels I had in my GT3 RS.

I've weight the same size 9x18 3pc race wheels and they are 3 lbs heavier. I wonder if any of us would ever notice a wheel that is 3 lbs heavier or lighter while driving on the track? I doubt it.

I'll chime in regarding the Dymags.
I had a set of Dymags on a 997.1 GT3. To the tee they weighed:
fronts 19x9 = 16 lbs
rears 19x12 = 20 lbs
These weights were absolute by scale. No guesstimates.
Got rid of them b/c they leaked horribly despite sending them back to England to be "fixed".
Now the HRE P40S in 18" made for me for the project are pretty light,

Ranger...any idea no what the HRE's weight?
I just weighted a OZ 9x18 Challenge wheel and it was exactly what Damon posted...21.8lbs. I weighed a Forgeline GW3R 9x18 and it is 25.0lbs. Both wheels weighted on the same scale. Yep the Forgeline was heavier (even though it's forged) but also a lot thicker on the wheel spokes too. So...what is better...thin light weight or thick and heavier?
