Great place and fantastic people. We got our car tuned here. They are helpful and a great fun group of guys. Dont forget the donuts! (In the yard)

Great guys. Very knowledgeable, honest and nice to deal with!

If you want to be ripped off, have your car given back to you in disarray, have bolts and parts missing, and be left wondering if your cars gonna make it then by all means, take your car to these fine gentlemen. If you dont mind your car repairs coming second to their racing habit and taking anywhere from 6 months to 2 years while also being inferior to anyone else then youre looking at the right place. Build process/quality? non existent. Customer service? gone after Justin gets his cut.

800 miles round trip$50 in tolls$362 in fuel for both vehicles$285 hotel$203 in foodPlus tuning fees and Id do it all over again!Early on in the initial communication with Loi at OTL I knew he was going to work out any issues i had with the existing current tune.Not only was his attention to detail spot on, but his results driven work ethic shined.At the same time, I always felt welcome with great hospitality.The moment you set foot in Off The Line Performance you can tell this was a shop designed by and built for by car enthusiast professionals. This isnt any speed shop, this place is special.The entire staff is welcoming and has the same goal in mind : progress & results coming from decades(maybe years for some) of knowledge.Loi & Sam put in countless hours on my car and never got discouraged, in fact we all find time to take breaks and enjoy the day when we could, which was a professional auto technician I can relate to 100%. Sometimes you need to walk away and think about something off topic to clear the mental cache.Additionally there were multiple other people behind the scenes reviewing logs,or bouncing ideas/data off each other which i greatly appreciated!TLDR; OTL is the best shop in Iowa, likely in the top 5 Midwest. Dont pass up this opportunity!

The guys at offtheline are some of the best people Ive had the chance to meet and they crushed every expectation I had when I took my 6 speed STI transmission there to get built. They are very personable and I would highly recommend the shop to anyone for any work they offer from basic bolt ons to the full can of sauce. Thank you OTL!

They replaced a head gasket for us on a 2010 Forester. Price was great and they didnt try to over sell. Will be taking our Subarus here from now on. Awesome to work with.

The new building looks Awesome! The people there are great to talk with!

Dont do what i did and fall for these guys and others who recommend OTL. Their quality and customer service is very inconsistent. They will swindle you out of quality at the minimum. Their services and engine options are overpriced. Beware, they may lose your car parts for months on end and expect you to wait a year for youre car to be repaired and then haphazardly put the new engine in (my brand new engines cylinder heads werent even done properly in the end. save yourself from getting shafted by these shady guys. They also left me a nice little dent on the crease of my door. also, somehow i ended up with a different intake manifold from another STI

Awsome services

Fantastic guys, always super helpful and knowledgeable

I began using otl in 2015. Since then I have moved across the country and still being many states away continue to rely on justin/otl for their expertise in the Subaru space as well as top quality parts.

Long overdue review. Found these guys under recommendation of a shop I used to go to in MD. Ended up spending lots of time with the owners and really appreciated the kindness work ethic. I had my car tuned by Junior through them as well, good prices and knowledgeable mechanics. Highly recommend for Subaru or any performance car need.

Had a breakdown with our Subaru, called here and got a quick response and diagnosis. Justin was great to work with, gave me some good feedback and even went above and beyond with the service.

Love this place. 10/10 recommend them to everyone. I even rep their sticker on my wrx. They have the best parts and everyone in that building is easy to get along with. Cant help but stopping in to say hi when I drive by. Bring your business to these guys. They wont let you down.

The guys at Off the Line Performance go out of their way to be helpful! From helping me find the right car for me to making sure I get in for oil changes, these guys have been there to help me with my every car need from big to small! Would definitely recommend.

Great guys, would definitely use them again. They went above and beyond. The true test of character is how a business handles mistakes and these guys are a breath of fresh air. When an incorrect part arrived for my car, one of the guys gave me his part off his own personal car (thereby stranding himself) to get me on the road and Mikey (rockstar mechanic) stayed many hours after closing to put the car back together for me. These guys are a class act. I read a couple of these reviews and am highly suspicious of what kind of person could manage to get a one star experience out of this awesome shop. They were hair on fire busy (happens when youre good) but still had time to fit me in. Justin (the owner) was polite, respectful, and apologetic that I would have to wait a bit.While waiting, I met folks who had come all the way from Alaska, Minnesota, South Dakota, New Jersey, Missouri, and some even farther just to have their car worked on. All left ecstatic with their work and wishing to return again soon.

Very knowledgable crew, friendly and accommodating. Best Subaru shop around. Would highly recommend.

Off the line performance is exactly what the title says. I took my boosted FRS there because it was having idle issues and I gave it to them and within the next will I had it back Dyno results and everything! We as a community of tuners need to get this name out there more because they jump leaps and bounds to get your car off the line

Great prices, superior Subaru knowledge. Creators of some of the most beautiful cars driven on the track.

Tried to go there on a weekday afternoon but the doors were locked, and no one was capable of answering and returning a phone call. Wouldnt waste my time trying to go again

Best parts, tons of experience.

Guys are the best!♡

Couldnt ask for better help.
