Forgestar F14 wheel weight with tires & hub rings
I know some people need to know the weight of wheels before they buy so here are some numbers with the tires on (Hankook Ventus V12's K110)
Front: 20X9 / 255 30 20 - 54 lbs
Rear: 20X10.5 / 305 25 20 - 59.6 lbs
I had a small vibration problem felt at about 45-50mph, the wheels came with their own hub rings, but when i checked the fitment, they seemed to be loose in the wheel bore but fit perfect on the hub, I ordered a new set with the correct size online.
I got Gorilla hub rings, put them in perfect fit on the wheel bore and hub.
I never believed that these things made any difference but it is like night and day, vibration gone. (Wheels balanced 2 times and an alignment done before the new properly fitting rings were installed)
Forgestar wheel bore size 74.0mm
CLS55 hub bore size 66.56mm

Flow formed wheels also known as a spun rim, all start off as a low pressure casting (the better of all castings).
The process is rather simple. After the rim has been cast (basic shape and design have been molded), it is placed into a CNC type of machine that first begins to heat the outer section of the casting. Second, high speed cutting rollers begin to slice and mill away sections of the rim to its final shape and specs. The combination of heat, pressure and spinning create a rim with the strength similar to a forged wheel, but without the high costs associated with forging.
BBS, to name one other manufacturer, also uses this technology to create some of their rims.
Some have dubbed these wheels... "the poor mans forged wheel"...
