King Motorsports Unlimited

Excellent service, competent staff!
Had my Honda supercharged and dyno tuned with these guys, now it rips!

I have been coming here for over a year. They are the only ones I trust with my supercharged 2014 Honda Civic Si. Huge bonus that they are the only Mugen authorized dealer in North America. The entire staff is very nice and very knowledgable about Honda tuning. People come from all over the country to get there Hondas & Acuras worked on/​modified here. They also have an amazing annual event called Dyno Day it’s just awesome to experience. Thank You to the entire staff at King Motorsports for everything you do.

Better rates than Honda or Acura dealerships. Excellent service, experience, and heritage. Had them do a OEM spoiler install on an Acura, looks great.

King Motorsports is the best!!!
I have been into the motor sports scene since the late 90’s and have been a regular at KMS since they were still in their Sullivan, WI location. While they have changed locations and some personnel, their commitment to excellence has remained the same.
I’ve had several motors (B18C5 & B16A2) fully built through King and NEVER had any problems with their work quality. These guys can build and or fabricate anything you need. In addition, their experienced and knowledgeable staff have bailed me out of a few DIY nightmares over the years.
Anyone reading this knows that King is the sole authorized Mugen distributor in North America. If you need Mugen parts, you’ve come to the right place. I’m currently in the process of building a 2009 FA5 and have already picked up a few key Mugen components for the build from Mike Lindquist. Mike is an endless stream of knowledge. If you have any questions about performance parts or anything else, this guy will surely have an answer for you.
I live in SoCal now and I would give King my business before any of the motor sports shops I’ve looked at out here. These guys have been doing things the right way for a long time. In my opinion, no one does it better,
