I like the look of the GMG's. Nicely finished. But for that budget, I think I'd go HRE or try the O.Z. (nice ad in Panorama) and I get fair price and local support out of Mr Shark of the Werks. (yes, I shamelessly shill for the local sponsors ... so shoot me ... no, really, shoot me ... maybe it will knock me out of this slippery slope free-fall ... : )

The price for the Superforgiatta is actually not bad, considering it's a high-quality forged wheel that is a centerlock. The Ultraleggera is NOT a forged wheel. It's made via "low-pressure" casting. I read that to mean zero pressure (well, room pressure at what ever altitude the factory is located). Cast metals are highly subject to porosity (small voids, typically caused by air bubbles). At least high-pressure casting helps to get rid of the air bubbles. These voids mean the material is not homogeneous and therefore not nearly as strong as billet. Forging is when you take a billet and smash it between two mold halves under tremendous pressure. It compresses the heck out of the material and actually makes the metal stronger.

High Light Technology (HLT)
The High Light Technology (HLT) process used in the manufacturing of O.Z. Racing's Alleggerita HLT and Botticelli HLT wheels, for example, uses rollers to compress and elongate the material along the barrel of a low-pressure cast aluminum wheel to obtain the desired profile. This process, which is directly derived from O.Z.'s experience in F1, produces wheels that are extremely light and strong.
The flow forming process and the HLT technologies combine to create mechanical characteristics similar to those of a forged wheel. This permits a dramatic reduction in wheel weight while enhancing structural rigidity vs. a standard cast wheel.

IMHO, OZ can not be beat for "value".

I'd get the cheap OZ, you can bend them a bunch of times before the they cost more, plus they look nice.
And if you stop trying to go drift king every corner and keep it on the black stuff instead you probably never bend them..

And they're available in simple black (a $400+ option on the venerable 4.0 RS, I might add ...) but with a $150K+ track car and other upgrades to reduce curb weight and unsprung weight and power train rotating "flywheel" mass, I don't want to get to literally where the rubber meets the road and say "oh yeah, that's where I decided to cut costs ..." : )
If I can get an appealing price on the wheels, then I'll spend a bit more and expect a lighter, stronger product, otherwise, I'll just get the factory wheels again as a second set and know I won't have any problem.

The OZ HLT wheels are super strong. I ran them on my last car. Blew a tire and went backwards over the race curbing. Tore the tire off the wheel. Not even so much a ding, let alone a bend. There was some curb rash the but the wheel was perfectly round.

I think the only major reason for buying superforgiatas over ultralegerras is for the 5-6 pound saving in weight per corner. Beyond that, as stated above, even the ULs would do track just fine...

If they made a proper fitment for my car, I would have bought the OZ allegeritas in 18" again. Unfortunately it's a 8.5 up front. Not that I'm disappointed with the CCW's I got from Randy. They're great wheels too. Except for the ****ty BBQ paint they use on them

Dog seriously all you need to do is wash them real
good spray them
Down with brake cleaner and wash them
Again. Go get some hi temp engine paint and mask off the tires with tape. 3 light coats wait 10-15 min between coats and your wheels will look like new and the paint will not flake off
