Family owned and operated since 1964, Performance Improvements is the leading retailer of performance auto parts and accessories with seven locations in Eastern Canada.

Performance Improvements ("the Modern Hot Rod Shop") was a part-time job for owner Bob McJannett in 1964. His goal in selling speed parts to fellow car enthusiasts was simply to make enough money to cover the rent. Success came as a result of a commitment to customer service, standing by every product sold with a no-hassle 30 day return policy. Over forty five years later, Performance Improvements has seven locations across Eastern Canada.
