CUSTOMER TESTIMONIALS

Kyle Brown

Had an 03 wrx tuned here today and all I can say is wow! Customer service is outstanding and the tune feels great. Riley and Brian were awesome to work with, thanks guys!

Josh Moss

I LOVE this place. The tunes are reliable the people are awesome! And helps you understand something and will help you out on what parts you need to buy before getting more power. I recommend hms any day!

Kevin Kidd

I absolutley love HMS. I wandered in with my Saabaru, unsure of what I wanted and needed for a tune and power upgrade. Robbie and Steve were happy to hang out with me and talk possibilites and options for my car. They didn't bs me, they told me and actually explained to me what parts did what and were actually interested in what I wanted my car to do and how I wanted it to perform. I wouldn't trust any other shop with my car!

Dakota Kittleson

when I first got my 04 sti this is the place that the dealership recommended to me so I gave them a try. got a stage 2 tune first thing and that was night and day compared to stock and the next time I went in I got k&n filter and mbcs and the power was unreal. the street tune is the best tune you can get in my opinon and these guys know exactly what they are talking about. Steve has Subaru knowledge back to when they first brought the wrx and sti to America. will not be going anywhere else as long as I live the customer service and skill of this place is off the charts!

Lane Fowler

What can I say about steve... Hes the man hes built my buddys 600whp sti. And now. Hes building my 650whp sti. Hes the guy to go to for a oil change tire rotation turbo upgrade. Build an engine. Hes the guy to go hms is the only place I would ever trust my 07sti with and with my money no other shop will see my money or my car. My business goes to hms only. Love this shop steve robbie are the coolest and nicest and most honest people out there I wouldn't trust no one else but horizontal Motorsports

Long time Just had my first true experience working with the guys down there when I decided to have them order me a set of Fortune Series 500 coilovers for my 2010 Legacy 2.5i, and they were very friendly and responsive to my questions and concerns thruout the process.

Dustin Pitzers

HMS has a hard to find stand up mechanic and a driven team that loves cars and also tries to help their customers understand what is going on with their car and what needs to be done. No BS here.

Garrett Born

Awesome guys that have treated me really well both times I've been. EBCS/tune tomorrow and I'm sure ill be just as happy as my last visits.
