GT-3 wheel weight comparison
Although there is a significant unsprung weigh difference over factory stock GT-3 wheels, if you buy a spare stock set, they are warrantied for two years. I drive the car to all the DE events and the factory wheels can handle the pot holes and road hazards far better than the other manufacturers you noted.

tyson and i are condsidering Cargraphic racing mesh at 16/17 # roughly F/R.
it's a trade off -- but GT2 wheels are roughly 4-5 # PER WHEEL heavier than gt3 wheels so the decision to take the breakage risk is even greater potential payoff.
i am am testing some fikse 13's profils on my gt2 over the next few weeks, courtsesy of Jack, and we'll see how much difference 28# less unsprung makes on my very bumpy mountain roads

I have 19" kinesis f110 one piece forged:
Available in 19 x 8.5 (18 lbs) and 19 x 11.5 (20 lbs)
pretty light.
anyone know what the SOLID turbo twists weigh (did a search and laid a goose egg)

do you guys know if the Brembo 15inch brake will fit?????
I'm thinking about either getting 15inch 8 piston....or the racing version 15inch 4 piston ones.....

BTW, that's 34 lbs of unsprung weight, which would require you to lose about 90 lbs or so to equal that weight savings.

Please explain this to me further. I'm a novice but I know what a weight change will do.

Unsprung Weight is a term used to describe that part of a vehicle's mass that is directly connected to the wheels, and not isolated through the suspension.
Because this part of a vehicle is in direct connection to the road and therefore subject to all of its imperfections, it is important that this weight be as low as possible, or at least much lower than the weight of the sprung part of the vehicle, in order that the wheels maintain optimal contact with the road surface. The greater the unsprung weight, the greater the inertia of the suspension, which will be unable to respond as quickly to rapid changes at the interface between the road and wheel. Unsprung weight can be reduced by using light alloy wheels, independent rear suspension (where the weight of the differential is not part of the unsprung weight).
