Burger Motorsports (BMS) & JB4 in Canada
Burger Motorsports built its name on one product philosophy: the JB4. A JB4 is a piggyback tuner that intercepts and optimizes the signals your factory ECU already uses — boost, fueling, timing — adding real power while the stock computer keeps its safeguards, its drivability and its ability to be removed without a trace. Around the tuner sits the supporting BMS catalog: intakes, intercooler and charge-pipe hardware, catch cans and the wheel spacers half the BMWs in any parking lot are quietly running.
Our BMS range runs to 80 products, and Canadian sales show both halves of the brand. The wheel spacers for BMW's G-chassis cars are the volume sleeper (49 sets in 24 months — the correct-width, bolt-inclusive fix for the factory tucked look), while the JB4 units themselves span BMW's B48/B58 cars and the EA888 Gen 4 application for the MK8 Golf R and 8Y S3. It's an accessible catalog: most orders are spacers, accessories and first-power mods, bought by owners who want a reversible first step rather than a committed flash.

Buying BMS in Canada.
BMS sells in US dollars from California; small-box cross-border orders are exactly where freight and brokerage hurt most relative to value. WCT carries the range priced in Canadian dollars, shipped from within Canada — free shipping on most orders over $399 — with the fitment questions answered before you buy: JB4 group numbers are platform-specific (a Group 18 EA888.4 unit is not a BMW unit), and spacer widths are a brake-and-fender measurement, not a guess. Ask us at 905-604-7077 or sales@wctperformance.ca; GTA pickup is at Unit 5, 151 Amber St, Markham once your ready email lands. We're rated 4.9 stars from 427 Google reviews.

Frequently Asked Questions
Q: JB4 or a flash tune — what's the difference?
A: A flash tune (034, IE, Unitronic) rewrites the ECU and generally makes more power with deeper control. A JB4 layers on top of the stock software, is removable in minutes, and suits owners who want warranty-friendly, reversible gains. Many customers start with a JB4 and graduate to a flash — we'll compare honestly for your car.
Q: Which JB4 group does my car take?
A: Groups are platform-specific — engine and generation both matter. Tell us the exact car before ordering; the wrong group won't work, and it's a ten-second check.
Q: What spacer width should I run?
A: It depends on your wheels, tires and fenders. Give us your current setup and the look you're after and we'll spec widths that sit flush without rubbing.
