JBM Performance

German vehicle performance tuning in Sheffield

JBM Performance is a Sheffield-based workshop that focuses on German marques, particularly Audi, BMW, Mercedes-Benz, Mini, Seat, Skoda and Volkswagen. The company describes itself as specialists in engine rebuilds, tuning, premium aftermarket parts and diagnostics. Its website is structured around a vehicle selector that lets owners identify parts for specific models and generations, from early Audi A1 and BMW E30 to current M and AMG models.

Workshop services

The workshop side of the business covers diagnostics, engine building, walnut blasting and vehicle inspections. It also handles transmission repairs, with clutch kits, flywheel and differential components listed among the transmission parts. Specialist services include dyno and rolling road testing, tuning and remapping, with dedicated engine and gearbox tuning for VAG/MQB and BMW platforms, as well as ECU and TCU software.

The online catalogue is organised by vehicle make and model, then by part category. Categories include brakes (kits, lines, pads, discs and components), bushes, arms and linkages, coilovers and springs, electronics (boost controllers, ECUs and gauges), engine components (cooling, coil packs, diverter valves, hardware, internals, oil, fuelling, hybrid turbos, OEM parts and turbo kits), engine and gearbox mounts, exhausts (axle-back, cat-back, centre sections, resonator deletes, over pipes, PPF deletes, quad exit conversions, downpipes/decats and manifolds), fuels and additives, intakes, maintenance and service parts, software, transmission parts and wheel spacers.
