If you're still consolable, here are some excellent wheels that are right at $1,000 per set (shipped), and they're rotary-forged just like the Forgestars, so they're very light and strong.
Several styles to choose from:
Nurburgring Alloy wheels in matte gunmetal, gunmetal w/ mirror cut face, and matte bronze by TSW | www.TSW.com

Less weight during articulation of the suspension = faster response time of suspension components = nimbler handling = faster lap times.
You are literally the first person I've ever come across to say that wheel weight is negligible in road racing.
There, I was helpful. As for under-the-hood stuff, it's all been covered in the thread at this point.
All the best,
