About us

Flat4.ca was launched in 2018 following the fusion of 3 small online and in-store parts suppliers.

Our sales team is dedicated to providing quality service and an outstanding customer experience. Our products selection is constantly evolving and we strive to provide you with the best performance and motorsport products, the most positive experience possible and the best for your money. We also want to offer products that are rare on the Canadian market: codriver accessories.

Every project deserves our attention and a peerless service, so whether you're looking for something as simple as a gasket or planning to build a rally car, we have the products and resources to get you to the stages or on the track. At Flat4.ca, we thank you for choosing us as your partner for your car project.





We think about the convenience of your choice. We've designed our car selector to help you find the right parts for your car which will considerably save you time and efforts. We've also added a feature that lets you choose for the desired application (performance or motorsport). What’s more, you can search our site if you know exactly what you are looking for.



 We deliver our goods worldwide. No matter where you live, your order will be shipped in time and delivered right to your door or to any other location you have stated. The packages are handled with utmost care, so the ordered products will be handed to you safe and sound, just like you expect them to be. Even though we work in the automotive industry, we care about the environment. That's why we try to limit overpacking. Anyways, the most important things are INSIDE the package, right?



Our store is more than just another average online parts retailer. We sell not only top quality products, but work hard to offfer our customers a positive online shopping experience. Need help to choose the right parts for your car? We're here to help! Can't find a product on our website? Tell us so we can add it to our selection! You've got questions about an order or need a quote? Contact us, we care about you!
