AFTERMARKET INSTALLS

Whether you're looking to carve canyons on the weekends or win your next racing championship - we've got you covered.

  • Aftermarket exhaust system? We've got you covered.
  • Big Brake Kit? No problem.
  • Coilover install? Piece of cake.
  • Bucket seats and harnesses? Let's do it.

We have experience maintaining and modifying street cars, race cars, and anything in between!

OEM MAINTENANCE

We are your one shop solution for keeping your car on the road! We can handle all of your maintenance needs including:

  • factory service
  • four wheel alignment
  • tire mounting/balancing

RACECAR MAINTENANCE

It almost goes without saying that the faster the car is the more complex it can be to maintain. We build and maintain all kinds of cars but we specialize in time attack and road racing cars (PCA, POC, NASA, SCCA). We are most familiar with Honda, Mazda, and Porsche.

We are the shop that you turn to when you run into issues that you can't solve with your K24-swapped Miata or LS-swapped BMW E46.

HONDA K-SWAP

We are the premier shop for custom Honda K-swaps on the west coast! Basic, boosted, or built - we have experience with most of the typical swaps and install kits but we've also done world first full custom builds like:

  • Fiat Abarth 124 Spider (K24 swap)
  • Volvo 1800ES (K24 swap)
  • EXR LV02 AKA Mitjet 2L (K24 swap)

As of 2025 we are no longer accepting new Honda K-swap projects. We are available for maintenance and aftermarket installation services but we have built enough K-swapped customer cars for a few lifetimes.

Here's what our customers have to say...

These guys are the best. They prepped, supported, and rebuilt my KMiata for racing with the POC. They’ve given me wise counsel on improving and developing my daily 997. They handle it all from the mundane to the exotic. Racers at heart who get you where you belong: behind the wheel and on the track.

Where do you want to take your car?....definitely, Walshmo Racing!!!!! My M4 was worked on with care, recommendations, and great communication. Pick-up time was on the money! Owner is genuine, friendly, and personable. Yes, Walshmo Racing was referred to me by a good friend and Walshmo Racing lived up to my expectations in every way.

Eric installed an aftermarket downpipe/frontpipe and front-mount intercooler to my FK8 Civic Type R. He did so very quickly and was true to his quote. He also helped tune the FK8 and was incredibly helpful and knowledgable in the process. You can count on me taking all my track-focused projects to Eric and his team. Many thanks

One of the few shops I trust to touch my S2000. Eric and his team are very knowledgeable and got me in and out in just a few hour when installing a LSD in my car👍🏽
