I finally got tired of waiting for Tire Rack to get anything from Brembo's warehouse, so they got cancelled :nec:.
A Google search found the same Brembo plain blanks at http://www.car-stuff.com/carparts/ho...-16095801.html for $36.95 each - $5 coupon code READY4SUMMER = $68.90, free UPS shipping. Saved $11.60 and at least 2-3 weeks if I'd waited for Tire Rack.
