Chassis No. DBRS9/7

The Aston Martin DBRS9 was conceived as a user-friendly alternative to the potent but complex DBR9, which was built to compete in the premier GT1 class of the FIA GT Sports Car Championship. The DBRS9 was instead homologated for the newly minted FIA GT3 class, which was developed to attract growing privateer teams to professional GT racing and bring one-make series like Ferrari Challenge to an international stage. Aston's offering was built to order through Aston Martin Racing and Prodrive at AMR's factory in Banbury, UK. Based on the road-going DB9, the DBRS9 sported an aluminum monocoque chassis with carbon fiber bodywork and a DBR9-spec roll cage. It was powered by a 5.9-liter V12 producing 550 horsepower and, interestingly, could be had with either a six-speed H-pattern or sequential manual transmission.

This 2006 DBRS9, chassis number DBRS9/7, was sold new in February 2006 to Autosport Designs, one of the many teams that were joining the popular SCCA Speed World Challenge GT class. Autosport Designs campaigned two DBRS9s and scored a season-best fifth place at Road America, with drivers Tom Papadopoulos and Johnny Mowlem at the wheel. Post-season, the Aston's V12 powerplant received several upgrades including Vanquish S cylinder heads, new pistons, crankshaft, and connecting rods, and a dry-sump lubrication system, pushing its output to 600 horsepower. Its Koni suspension was also revised with Moton shock absorbers with adjustable sway bars.

The car was sold to John Sinders, then part owner of Aston Martin, who tasked Rahal Letterman Racing (RLR) with updating the DBRS9 for use in SCCA Pro Racing World Challenge before the start of the 2008 season. Under the watchful eye of Bobby Rahal himself, the crew moved the engine six inches back, shifting the weight distribution rearward by five percent, revised the suspension, and lowered the ride height. Clad in RLR colors and with sports car ace Tommy Milner at the wheel, the DBRS9 secured pole position and finished second at Road Atlanta as well as fastest lap at Mid-Ohio where it would finish in fourth place.

DBRS9/7 retired from racing after 2010 and joined the esteemed Mancuso Collection in Illinois, where it was painted Aston Martin Racing Green. It then passed to private collector Jeff Urbina before a public sale in 2015. Under the care of its current owner, the Aston's V12 powerplant was sent to Katech Engines in Michigan for a full engine rebuild and dyno testing. With the engine removed, Scott Lagasse Racing inspected and serviced other critical components including the fuel system, clutch, brake master cylinders, and suspension. Service records show this roughly $46,000 restoration took place from 2019 to 2021.

With approximately 26 customer DBRS9s built, and DBRS9/7 is believed to be the only example in the United States. It is now clad in an AMR Green livery along with the more approachable six-speed H-pattern manual transmission. The sale includes extensive service paperwork and DBRS9 technical documentation from Aston Martin. Eligible to participate in series like HSR and Masters Historic Racing, this gentleman's racer fits well into most appropriate historic racing events and is a formidable weapon at any track day.
