BMW & BMW M Performance Builds
M3, M4, M2, M5, X3 M, plus the B58 and N-series M Performance cars. We build BMW M platforms as coordinated projects, not a pile of parts.
LMK Garage is a BMW M and M Performance specialist serving Richmond, TX and the greater Houston area. We work on the platforms enthusiasts actually build: the S58 G80 M3 and G82 M4, the S55 F80/F82 generation, the S65 V8 E9x M3, the S63 F90 M5, and the B58 / N54 / N55 cars that respond so well to bolt-ons and calibration.
The strongest M builds are sequenced, not bolted on at random. We coordinate the whole car (exhaust and intake, suspension and alignment, wheels and proper fitment, exterior finish, and interior work) so the result looks intentional and drives like one build instead of a parts bin. Performance calibration (ECU/TCU) is handled together with Launch Labs.
Below are the BMW M chassis and engine codes we regularly work on. If your platform or code is not listed, it usually still fits what we do. Send your vehicle details and we will tell you what makes sense.

BMW build FAQ
Do you work on BMW M cars near Houston?
Yes. LMK Garage is based in Richmond, TX and serves the greater Houston area for BMW M and M Performance builds, from the E46 M3 through the current G80 M3 and G87 M2.
Can you tune an S58 or S55 BMW M?
We provide performance hardware and install support for S58 (G80/G82) and S55 (F80/F82) cars, and ECU/TCU calibration is handled together with Launch Labs. Send your build goals and we will scope the right combination.
What is the difference between the S55 and S58 engine?
Both are 3.0L twin-turbo inline-sixes. The S55 powers the F80/F82 M3 and M4 generation; the S58 is the newer engine in the G80 M3, G82 M4, G87 M2, and X3 M/X4 M, with a revised architecture and closed-deck block.
Do you do exhaust and downpipes for the G80 M3 or G82 M4?
Yes. We install downpipes, catback systems, and valved exhaust for S58 cars, coordinated with any supporting calibration so the result is clean and drivable.
