Racing Comes Full Circle at Duman Turn 4 Restorations

Who better to work on vintage Indy Cars than the mechanics that worked on them originally? The name, Duman's Turn 4 Restorations based in Brownsburg, IN comes from Rick Duman's childhood home at 25th & Georgetown across from Gate 9 at the Indianapolis Motor Speedway (the original credential gate). 

Rick's father, Ronnie was an USAC driver active in the 1960's.  Ronnie built a four-plus car garage at the house on Georgetown Rd. Later it became the original home of Michner-Patrick Racing, later Patrick Racing. After a short-lived midget racing career, Rick moved from behind the wheel to wrenching on race cars. By the mid-1980's he had worked his way up through the ranks to chief mechanic for Tony Bettenhausen Racing, winning the George Bignotti Preparation award in the 1992 CART's series and mechanic of the year. Later Rick was a race winning lead mechanic for Target-Chip Ganassi Racing and in 2005 Rick won the Clint Brawner Mechanical Excellence Award (formally the DA Lubicant Award) at the Indianapolis Motor Speedway.

It's behind Rick's leadership, that a crew of experienced former USAC/CART mechanics bring alive the history of open wheel racing, Turn 4 Restorations has experience working on two-seat Indy Cars of the 1930's, Offenhauser-powered roadsters and upright Championship Dirt cars, sleek grand prix inspired cars of the 1960's and 70's to the near modern Lolas and Dallaras of the 1990's and 2000's.

Duman's Turn 4 Restorations has an open door policy but with a high-tech secure location amongst the burgening motorsports area on the West-Side of Brownsburg, give them a call first.
