Built for serious metal
Performance, repair, and engine work for European and high-end cars.
The atelier
A black-box shop for cars that still matter
TUS Shop Inc., The Upgrade Shop, is the performance-capable repair shop between River Falls and Hudson. Peyton Sherman built it for European, exotic, and modified cars that need diagnostics, engine work, and upgrades under one roof.
The pin is 663 Valerie Ave, Unit 123, River Falls, WI 54022. Hudson is about five minutes north on Hwy 35. Downtown River Falls is about ten minutes south. Shop rates, no Crest View Drive traffic.
Areas we serve
Three disciplines. One bench.
Tire shops own wheels. Dealers own warranty. This shop owns the work those two will not mix: a timing job in the morning and a turbo install in the afternoon.
Performance upgrades
Turbo, exhaust, suspension, brakes, and ECU work for European, exotic, and seriously built daily drivers.
- Turbocharger install and diagnosis
- Custom exhaust fabrication and tuning
- ECU calibration for modified engines
- Coilover and geometry setups
General repair
Diagnostics, brakes, suspension, drivetrain, and maintenance for drivers who want the same shop that builds engines.
- Dealer-level diagnostics and check engine work
- Brake, rotor, and hydraulic service
- Suspension, alignment, and chassis repair
- Drivetrain and transmission diagnosis
Engine swaps and rebuilds
Cylinder head work, complete rebuilds, and engine swaps for cars that deserve more than a used long-block from a catalog.
- Cylinder head, valve, and head gasket repair
- Complete engine rebuilds to spec
- Engine swaps with supporting fuel and electronics
- Timing, oil pump, and bottom-end restoration
From the bay
BMWs on this floor, not stock photos
These shots are from Unit 123. M cars, 3 Series, and X5 work sit first. Other platforms still get booked; they just do not lead the site.
Cities we actually serve
Google only ranks what you declare. These are the towns The Upgrade Shop covers from the River Falls 54022 address.
How a visit works
- Call or send the car. Name, phone, year make model, what is wrong. Nothing else.
- Inspect, then talk. You get the diagnosis before a parts order.
- Work, then document. Performance and engine jobs are photographed so you can see the build.
