Corner Speed Tuning

Just had my oil changed, great friendly service. John knows his stuff. Gave me information about what the next services for the car will entail. Always friendly and never talks in a condescending manner like some mechanics will do. Prices are fair for the work that is done. Will continue giving my business and already have referred others to him.

John is da man!
I’ve known John ever since he worked at that tuner place in Fountain Valley. He is thorough and meticulous, explaining what he is doing if you ask. He genuinely cares about his work and will go above and beyond to help out his customers.
While he mainly focuses on Subarus, he will also work on all kinds of cars. He is more of a maintenance, install, and street and track setup guy; don’t call him expecting he will chase down an oil leak, he’s not that kind of shop.
He’s just getting started. Looking forward to seeing what the future brings. Expect to see some fast cars on the tracks set up and prepped by John.

I usually do not write reviews but when it comes to awesome service and helpfulness this shop right here deserves a full 5 stars. I come from the automotive background (bodyshop) and I know how stressful it is running your own shop and working in the back. John is probably one of the most knowledgeable guy that I have ever met. If you have an issue with your car or want something install I would recommend him 100% over anyone. Very clean shop and great owner/​worker.

Good dude. Meticulous. Attention to detail. Fair prices and quality work. Would recommend.

For the past 10+ years, I’ve done every bit of maintenance and parts install for all my vehicles myself. I had always been skeptical about letting anybody else do the work on my vehicles, especially these days, where it can be really difficult to find a trustworthy shop.
It’s gotten more difficult as life has moved on though. Work, school, family etc has made it become a pretty difficult task to get into the garage sometimes to do even some basic work. Luckily, I stumbled across this place on the forums and realized that it was close by to where I had just moved. All the reviews I had seen were positive, so I figured I’d give it a shot.
I couldn’t have been happier. The work itself was very easy (brake flush and oil change), but the work was done in a timely manner and the car was returned in the exact condition that I hoped. No smudge and dirt marks everywhere, no fingerprints all over the car etc
What really got me was that I spent the most time there just talking with John about countless different topics; mostly car related. It’s great to go somewhere, though, where you aren’t just pushed in and pushed out. I had enjoyable conversations during both visits and learned quite a bit during the interactions with John. I never felt like I was bothering him or inconveniencing him by staying and chatting.
What I enjoy most is that John is very straight up and has real integrity. He won’t just spoon feed you nonsense in the hopes of getting more money or plugging friends’ services. He takes into account what your expectations and goals are and gives you the information to help you get there.
I’d recommend John and CST to any of my friends. In fact, I need to make an appointment to go back cause I have some more stuff I need to have done for an upcoming track day!
Keep doing what you’re doing, John!

John great work. Had him do the clutch on my 98 Outback. Honest, great pricing, fast response time. I called in for a quote and was emailed back with it within 10 minutes. My clutch feels great now. I also have some oil leaks to get fixed next week. I’ll do a follow up for that, but I’m sure it will be nothing but excellent work. Be sure to set appointment as the shop is small. Thanks John !!!

John is the best! He is very meticulous with his work and does the job right the first time. Bring your parts and have him install it for you. His prices are great and competitive. John also track his car so he’s very knowledge with different variety of setups and could provide suggestions. You could watch movies in the waiting room too. I brought my 2015 STi to have performance parts installed and he completed faster than expected. After completion of the installs, he will walk you thru what was done. I highly recommend John.
I drove from LA to Huntington Beach just to have him work on my car :)

First off I just gotta say, I don’t do many reviews on Unilocal,but when someone does an awesome job, they deserve it.
I drive a 2007 Subaru Impreza WRX STi and decided it was time for some routine maintenance. Heard a lot of great things from friends about Corner Speed Tuning. John is one of the most friendly mechanics I have met, him being a former COBB employee is just a plus. Knows a ton about Subaru’s as well as many other types of vehicles. The work I had done was a typical 3k oil change as well as rear diff oil change and tranny oil change. While talking to him, I asked what type of difference will I feel with the tranny oil change, his response was you will have butter smooth gear transitions, and WOW! It was like driving off the Subaru lot after getting a new car! He has tons of OEM Subaru oil filters and crush rings on hand, and not to forget he has Motul oil on deck, which is what I used for all the new fluids.
Definitely coming back for my 60k maintenence check!

Took my old legacy wagon in for a tune up. John was excellent, I feel I was charged fairly for the work and parts needed. He got the work done in a good amount of time and was very polite. I am very happy with my experience here and will definitely be taking my wagon to him for maintenance. My car has almost 200k on it, it was feeling really bad before I went to the Corner Speed Tuning. I drove away with a smile on my face after feeling my cars engine running strong again all after only a tune up. I highly recommend John Lindeman to anyone not just for Subaru but for other cars as well.
Thanks John!

I recently got my Subaru 30K service and fender rolling with John and I am more than pleased with the service and the work he has done to my car. John is very easy and friendly to talk to and I don’t think anyone would have any problem getting along with him. This will be my go to place for my future mods and services from now on. I recommended my brother who also drives a Subaru and will also be coming here shortly to get his 30K service done. John provided me with a can of coke but next time I go there I’ll be bringing in some water. If you are worried about what to do while your car is being serviced, there is a TV with Netflix so you can watch that.

John is one of the few guys out there for us track guys. He ‘gets it’ when you tell him that you are a track rat and want to build your car accordingly. John is very detail oriented and very meticulous when working on cars. His shop is clean and orderly which translates to the pride he has for his business.
His prices are reasonable, his work is fantastic, I highly recommend John for all your car (race) needs.
This guy is also a racer and a good source of knowledge for driving technique and how to drive fast on socal tracks.

I love this shop! I’m very grateful with John, thank you so much for all your help. He’s the only person I trust with my subaru. :)

When you have some car knowledge and don’t mind sharing it, your considered a cool person in my book. I have gone to the shop and spoke with «J» for hours about car stuff. What works, what doesn’t. What his opinion was on items and why. I have driven from the other side of the city of Los Angeles, to have him work on my car. He has done a few things to my car and I have no complaints about anything. Any time I need some stuff done to my car in the future, I will be bringing it back here. Thanks «J»

John at Corner Speed Tuning, did a great job. I had amassed a small batch of parts, and John was more than willing to put them on. He was super knowledgeable and helpful. After he installed the parts, he brought me in to see all the new parts that he had installed. After John’s hard work, the car is running harder than ever before. Thanks for your hard work and help. See you for service or if I have any other parts that come up

Corner speed tuning is a little shop that caters to many if not all the needs of all car enthusiasts alike. John, the shops owner, is very knowledgable and is very friendly and approachable. Unlike many shops out there, he will not try to up sell you, sell you things you do not need, will only work on what is requested and will only charge you on work that was done.
I came in to have koni inserts installed for my 2012 Wrx as well as a reinstall of a rear sway that I installed upside down. Naturally, I had many questions before setting an appointment. John was very patient and answered all my questions.
Upon arrival, I was welcomed with a very friendly hello, and had a small chat about how he came to open corner speed tuning. A couple hours later I received a call and was told the work was completed. When I came to pick up the car, he noticed some things that were installed wrong by either a previous person or myself, and corrected it with no charge to me. He explained what was wrong and it was good to know because most shops will do the install, and leave me to it.
Look no further for your sport car needs, price is phenomenal, shop is in a convenient location, and work is 5 star.

Though I haven’t been to John’s current facility, I can speak of the man, his capabilities, and his character. John really is a class act, he is a fountain of knowledge when it comes to cars, he’s obsessed with detail and perfection when it comes to working on them, and he’s a great person to boot. I highly recommend him for your car’s modification and service needs.

Cornerspeed is excellent. John’s knowledge goes a long way. If you’re looking at getting work done on your car right, this place is the place to go.

Brand new opened one man shop, years of experience with Honda, Subaru, Mitsubishi, Nissan and other cars that Cobb would tune, as he was THE mechanic at Cobb SoCal for years.
Now, I rarely write reviews because I don’t rave about the standard/​usual expectations out of a place, i. e «omg Xxxx shop did my oil change and now it runs so smooth» well no Sh1t, new oil, it’s supposed to be smooth. Get what I’m saying?
Back to John, the owner of Corner Speed Tuning. This guy will literally every question you have before you commit to getting any work done. He will make sure you have the right, quality part and if you decide to do some work on your own before hand, he will give you tips and guide you if needed. For my case, I chatted him almost daily for a month and he has helped me all along.
Bottom line, exceptionally humble guy, knowledgeable and his prices are more than fair PLUS he doesn’t take short cuts. If you want your car done right, give him a call and test him out yourself.

I first met John when he was a mechanic at Cobb Tuning SoCal. He worked on porting my turbo because my 2012 STI has some boost creep after a pro-​tune.
Fast forward a few years later, I went back to him for a turbo inlet hose and anti-​lift kit install because of the outstanding job he did while at Cobb. The level of attention to detail is amazing! During the install of the anti-​lift kit, he noticed some imperfections in the kit (brand new, unopened). He showed me exactly where they are (it happened to be on both sides, same location, possibly during manufacturing), but they were slight.
I also wanted to get a new fuel pressure regulator installed, but John saw a potential issue installing it without getting a quick fine tune to smooth out the tune map. He explained to me all the issues (although minor) that may happen, and I decide to hold off on the FPR install. I picked up the car a few hours later, and he even took the time to clean out my dirty intake filter!
The car drives fantastic and the work he does definitely shows. You can’t go wrong with Corner Speed Tuning. I’m definitely going back in a few months for more installs.
Highly recommended!

So the owner of this shop, John, has been a real good buddy of mine for many years. Met him early on when i got into the subaru scene and has helped lead me in the right directiom when it came to my build. Super knowledgable and one of the friendliest people you will ever meet. No question is too dumb for him, he will answer any and ALL questions in a way that you will full understand. His work is another fine thing, he is extremely meticulous and careful when it comes to his work. He is fine example of how all shops should be. He has been working for his own shop for a long time and im really glad to see him achieve it finally! I would recommend this shop to anyone and everyone!!! Look forward to coming back in the near future!
