P.I. Speed Shops

We can't fix your car, but we can make it better!

Over 55 Years of High Performance in Canada

In the performance auto parts business since 1964, Performance Improvements prides ourselves on serving the needs of our customer. As car guys (& gals) ourselves, we know the frustration of laying in the driveway missing the part we need to get back on the road! We try to help you take home all the parts you need to actually install that performance auto part or accessory on your car.

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.

Henry Stancu wrote a nice article about the beginning of P.I. in the Toronto Star:

Auto-parts firm built on blind faith and fast cars

Bob McJannett's passion for customizing hotrods, along with his wife's support, made Performance Improvements a 50-year success story.

Performance Improvements - Help With Warranties

We're here to assist you with any warranty issues. A warranty means nothing if the shop you bought it from makes you deal with it on your own. Performance Improvements has relationships with all the major automotive aftermarket manufacturers. When our customers have a problem, and the manufacturer does not demand that all warranty issues go through them, we do our best to help our customers until it's resolved.

P.I. Speed Shops - No Excessive Duty, Brokerage "Handling" Charges

No Summit Surprise! Canadians buying from the big American mail-order companies have learned the hard way that the price you see on the screen, is not the price you pay when it gets to your door. Shipping & "Handling" charges, Duty, Brokerage Fees and Taxes all end up making the price vastly higher than the original number. Summit Racing has finally updated their shopping cart to show customers the various shipping charges they will be facing: Shipping Charge, Tax & Duty, then an Additional Shipping Charge, and finally a Delivery and Handling Charge! Support your local Speed Shop.

Family Owned Companies are Always the Best!
