Quality Craftsmanship

Balancing Performance & Budget

The chassis is the backbone of a vehicle, and often in classic cars that backbone is rusted, heavy, and less rigid. A Rothspeed chassis is performance, and more.


Rothspeed Chassis are designed with the customer and builder in mind. Easily serviceable parts and a durable construction make for a cost effective ownership


Rothspeed Chassis are designed to perform. A low roll center, increased camber gain, and near zero bump steer make for a performance chassis that excels on the racetrack, yet is still comfortable on rough roads.


Using durable and high quality parts, our chassis are designed not only to perform, but to last.


We have a strong relationship with suppliers. We are able to offer high quality parts at extremely competitive prices.

Born Out Of Necessity

Rothspeed custom chassis are the product of the construction of SplitRay®, and the beginning of SplitRay® phase two. Building SplitRay® revealed an opportunity to fill a gap in the chassis building industry. Read the story behind award winning SplitRay®, and the experience that led to the creation of Rothspeed
