Bottom line: You can find quality 17" Porsche takeoff 17 x 8.5 wheels that weigh 21 lbs for around $125ea on CL or you can buy ultra lightweight (18lb) racing wheels for $2500 ea. Shaving 12lbs of unsprung weight might buy you 2/10sec per lap. Are there more efficient ways to spend your $10k that will yield higher performance? Adding a 3.8L motor (2-3sec)? Professional coaching by Andy Lally (8sec)? Tires (5sec)? Suspension (2sec)? The low hanging fruit is always the driver, not the wheels.

People always overlook their driving skills.... Like instead of thinking that each lap wasn't fast enough so they make their car faster, they should just keep driving and going to driving schools...
And as previously stated, the difference between a 18 and 14lb wheel is not that noticable... If you're trying to be faster, when it comes to wheels, go smaller....
Driver before car... Driver. IMPROVE YOUR DRIVING! GO FORTH!!!
