Over 55 Years of High Performance in Canada
FIRST LADY OF PERFORMANCE - Performance Improvements co-founder Susan McJannett out front of the original location at 1268 the Queensway in her 1958 Pontiac Parisienne two-door hardtop.
Canadian Family-Owned Speed Shop
In 1964, a young Susan McKee was tired of listening to her boyfriend, Bob McJannett, complain about the bad customer service he received while buying his performance auto parts, and thought they could do better. She invested all her savings, $1,500, to open their own part-time speed shop in Etobicoke. (Susan wisely waited a year to see if her investment would pay off, before investing in Bob and becoming Susan McJannett.) Over 50 years later, this family-run Canadian business is still going strong.

HIGH PERFORMANCE COUPLE- Bob & Susan McJannett turned that $1,500 investment into a successful chain of Speed Shops.
All Canadian Speed Shop since 1964
Toronto based Speed Shop since 1964. Originally located at the corner of Kipling and the Queensway, Performance Improvements ("the Modern Hot Rod Shop") was a part-time job for Bob. His goal in selling Carburetors, Manifolds, Mufflers, Wheels, and Tires to fellow car enthusiasts was simply to make enough money to cover the rent. Success came as a result of the commitment to customer service, standing by every product sold with a no-hassle 365-day return policy.
