Time to call in that favor from Santa. Pratt & Miller Engineering will begin taking orders for its Corvette C6RS this December, confirming rumors of a production version after its official debut last week at SEMA. Deliveries of the 600-hp, 600 ft-lbs. monster 'Vette will begin in April next year, as long as you can provide a donor car (C6 coupe, convertible or Z06) and the $185,000 necessary to complete the build.

In addition to the Katech-modified 8.2-liter V8, copious quantities of carbon fiber replace many of the standard components, while 18x11-inch wheels up front and 19x13.6-inch BBS wheels out back cling to the corners of the C6RS, which is a full 1.6-inch wider than a standard Z06.

All the details are available in Pratt & Miller's press release after the jump.
