The old Japanese made Champion forged wheels were fantastic. Strong and light.
My 8.5 and 11.5 rs171s with 235 and 305 tires came in at
According to Nitto (https://www.nittotire.com/car-tires/...formance-tire/)
when new, those fronts are 23 lbs and the rears are 33 lbs so the fronts are 43-23 = 20 lbs and that's with air and a center cap and the rears are 53-33 = 20 lbs with air and a center cap. Rears were more worn so probably off by a pound or two, but still really light. They were actually lighter than my current Forgelines, who are know for their wheel lightness.
Wow. Bravo! If those weights are accurate you are in magnesium lightness territory. Lots of forged aluminum there and 1-piece monoblock construction (3-piece look is only cosmetic, according to their website).
I have some forged OZ wheels in 9 & 12 by 19" and the flow formed Ultralegerras were 23.4 and 26.2 lbs and my new Superforgiattas are 19.0 and 22.2 lbs.
The 997 GT2/GT3RS forged OEM wheels in those sizes are 23.0 and 27.5 lbs.
Here's a shot of the UL on my car and the SF held beside them:
Those above are obviously centerline wheels, but I've only seen the BBS F1 mag wheels in comparable sizes weighing less than the OZ SF.
$11,900 for a set of 4.
They only come in 20 and 21", but the weights are: 20x9.0 17.4 lbs 20x12 20.5.
But look what BBS removed to get those values (the OZ individual spokes are scalloped and the hubs are drilled out from behind):
These were a set of Japanese made Champions from the time that they were being outsourced from Tan-ei-sya factory in Japan. Like you said forged Monoblock 1piece with the classic look of 3 piece. They used Titanium screws to keep it light.
While I did not physically put these on the scale to get the exact weight, the weights were given to me by the previous owner and I would have no reason not to believe him. Thanks and nice wheels!
Thanks, I got them here on Rennlist Marketplace, been looking for a NB set for sometime, hoping to get some what local, as it so happens these came listed a little over an hour away and I snatched them up!🤙🏼
OZ Superforgiatta in 9 & 12 X 19' w/ MP4S 245/35 and 325/30
Front ET 47 18.8 lb
Rear ET 48 22.0 lb
Noticeable improvement in steering feel. Every pound decrease of unsprung weight is equivalent to 2 pounds of sprung.
About $6K at Tire Rack. No longer being manufactured in 997 size- but some stock remains at factory and available in 19" by special order.
I chose the engraved white lettering (that comes standard on the black wheel- but not the grey finish) delete option, which is no charge since the wheels are unfinished and only painted after ordered:
