The GS valved Bilsteins are fine for my aggressive street driving.
Perhaps a bit more about your braking goals would draw advice best targeting your needs. I understand the Z06 red calipers are just painted stockers.
Enjoyed my visit to your area last weekend; nice hills, but'd be nicer in my Vette than the rental car. Got my new Vette sign at Hemming's, in Bennington, VT, too!
