Pro-Touring Capabilities
Advancing from the 20+ years history and knowledge of the builders at Attebury Street Rods, ASR Performance is moving towards a new vision in the industry. With the recent changes in the vehicle marketplace, and a passion for Ford Mustangs, ASR has expanded its approach to now include muscle cars and pro-touring street machines.

What started as a vision of Matt Dowd’s years ago became reality in 2013 with the completion of the first Independent Front and Rear Suspension for 1967-1970 Mustangs. In 2014 the first IRS and IFS prototype went to production and was installed on a converted right hand drive 1967 Ford Mustang debuted at the SEMA show and invited to the Optima Ultimate Street Car Invitational. Proving its pro-touring capabilities with completion of the events, track time and over 1,200 miles driven in one week.

ASR Performance is excited to expand our capabilities and to take our experience and apply it to not only hot rods and street rods, but also muscle cars and pro-touring vehicles now.
