365 Day Return Policy

We stand behind everything we sell. Our no hassle return policy gives you peace of mind with every auto parts purchase from Performance Improvements. Almost anything you buy from us, you can return within 365 days for exchange, credit or refund if it is unused. All we ask is that you keep the packaging intact & have your receipt. See full details and exceptions on our Return Policy HERE.

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, we help them until it's resolved.

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 they see on the screen, is not the price they 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! Don't forget the surprise you get opening your credit card statement to see what rate they decided to use to convert your US bill into Canadian.

We're Here For You - Locally

All our salespeople are here to give advice. Whether on the best way of installing a part, or where to find the best local mechanic, we live in your neighbourhood. We have Performance Improvements auto parts stores located across Southern Ontario and in Quebec: Barrie, Brampton, Guelph, Hamilton, Oshawa, Pierrefonds, and the head office in Toronto. We support local car clubs, car shows and racers. We are not owned by a foreign company, we are proudly 100% Canadian. We deal with manufacturers directly - when you buy your parts from us we can get you the help you need. If you order the wrong part by mail order you have to pay to send your part back across the border and then wait for someone to get to it.
