Darwin is a great mechanic with very fair prices. Since moving to the bay area its been hard finding a mechanic I can trust but Darwin is very good at what he does. Theres no other place Ill take my car now and happily drive from SF to Hayward when I need a repair.

Darwin is the guy to go to meet your installation needs. His prices are fair & not overblown. He quoted me $200 brake pads & rotors plus braided lines installed.Not a bad package deal.

Darwin is the man! I’ve been a customer of DNR for many years, since their old location on Industrial Blvd. The new shop location on West Winton is really clean and is in a more secluded area, which is perfect for ‘non California friendly cars’ hence the new ridiculous laws the state is enforcing. Darwin has been taking care of my Prelude since I first got it 6 years ago. Everything is running flawlessly when Darwin is around! I highly recommend him if you have any problem going on with your car or any build you’d like him to do. He will do everything he can and he’ll treat your car as his own! Very honest guy and true to his word. I’m always impressed by his amazing work. I will continue to do all my maintenance and future builds here.

Great customer service and very easy to work with.

DNR Specialty Performance is the one stop shop to have anything done! I’ve been going to these guys for years and til’ this day they have not let me down. 2 thumbs up!! 👍👍 great quality work and professionalism.

Excellent service.

Darwin Took a month for diagnostic, scratched my new paint, worst experiance ive had with any mechanic EVER ! Would NOT recommend even if it was FREE ! Save your time and patience and go anywere else... Double thumbs down 👎👎😵...Wouldnt give the place a single star

Formerly owned by my good friend David Nguyen now operated by Edwin. Still a great place to get your car worked on and Edwin has become a great tuner. Fair price!! Come check it out... specialize in Hondas and V8 (LS1) and lot of old American muscle cars get worked on here as well. Disclaimer: Im partially sponsored by Edwin as he dynos and tunes my cars. :) But I help him out in return as well... come see us you will not be disappointed.

Sent them an email to make a dyno tune appoinment and never responded. showed up to their shop with my skyline and the asian dude dont know his name told me to make an appoinment thru email. didnt even try helping me to get an appointment . a la verga entonces pinches putos

Guy I got k24de on my 84 king cab whit turbo I i want 2 know the top hp can have?

I visited this shop not to long ago to dyno tune my EG6 and I have to say that Im completely satisfied with the HP gains. Edwin is by far one of the best performance technician known in the bay area. Professionalism along with quality is not easy to find, at DNR Performance you get the best of both worlds. I recommend this performance shop not only to import enthusiasts but also domestic cars as well. Edwin and his staff will make sure to provide superb customer service and professional advise. Ill definitely be back to further improve performance on the Honda. Ive had nothing but great experiences at Edwins shop.

Excellent service excellent work and always with a smile you cant go wrong having your car worked on there Edwin is an excellent mechanic and a fair one

Great place lowered two of my cars! No complaints here.

Best place to go for your race car

I called in to get a tune up on my car he told me he would call me later that day but he never did. Then I called him to next day to remind him he never called me he gave me some attitude and told me he will work on my car Friday. I called him Friday he told me he was backed up on work and that he will call me Thursday. I waited till Thursday then I called just for someone to tell me he went on vacation and he won’t be able to work on my car for another month. What a huge waste of my time!!

They definitely know their stuff and Edwin is super chill and very helpful.

Nobody ever picks up. all i i wanna know is how much for a B16 swap into a 93 Civic coupe?.... id rather not leave my number on a public forum. is there someway i can email you? your voicemail box is full.

Best shop for dynotuning and complete auto repairs,very satisfated with there service.... Highly recommended!

They do great work on cars. They love the classics.

I call them they gave me the information I need over the phone for free Thank you DNR
