Redline is a top-notch company with great customer service and excellent parts. Redline is a top-notch company. I was able to locate, order and pay in just a few minutes. The website is laid out well and navigating was a cinch. I received a confirmation email in just a few minutes after my ECU purchase and I received email when my order was ready to ship, when it was shipped and included a tracking number. The ECU arrived well packaged and was in excellent shape for an ECU that was over 20 years old! I plugged it into the harness and the Miata fired up first try! Thank you for a great buying experience and I will highly recommend your parts and services to all my gearhead friends!

Great Service and Fast Shipping ! Great Service and Fast Shipping ! I’ve bought a couple of things in past. Every purchase included all hardware, clips; etc!

What makes me a repeat shopper. The time the salesperson took to make sure that what I needed was in stock and available. After everything checked out the courteous and reliable way of putting my order together and shipping it in a timely matter was spot on to say the least. I would definitely shop again with you. My parts arrived neatly & professionally wrapped as so not to be damaged not like some of your competitors who don't really take the time. Thank you

Incredibly fast shipping Incredibly fast shipping. Received the rather large items, perfectly packaged in 48 hours.

Came through as advertised. I decided to do a search on some parts I needed and I’m so glad I found Redline. They seemed to have the part I needed so I called to verify, they answered all my questions, and yes, just as advertised. They had it and at a very reasonable price and they shipped it faster than I expected.
