The first Funny Car chassis to be built in-house at Don Schumacher is about to be retired.

Jack Beckman revealed Sunday morning the DSR-1 Funny Car chassis has one more race, Topeka, before being replaced by DSR-4.

“This chassis has been front halved twice,” said Beckman adding, “its just time for a new chassis.”

The new chassis will have several improvements built in, including some meant to further reduce and/or relocate weight. Beckman says from a driver standpoint it's difficult to tell one chassis from another unless there is a major change in the steering or relocation of a significant amount of tubing.
