Great Customer Service Had an issue with wrong rotors and ECS made it right without me even asking. Their selector showed rotors that did not mention vented or not. When I received them and took my mine apart mine were vented but 5he ones ordered were not. I called up and they said, don’t worry we will get the correct ones to and they did.

Don't rely on ECS Tuning application guide Based upon website guidance, I ordered an auxiliary input wiring harness for my 2003 Mercedes C240. I received it, decided to do some online verification before opening the package. I learned this harness wasn't compatible with my car's wiring. After a lot of hassles I was authorized to return it. I paid shipping both ways for a part incorrect for my car, despite the website claim it would work.

Garbage parts Bad customer service Garbage parts. Defective and cheap spoiler. Looks like junk on the vehicle. If your past the return window good luck getting a replacement! Their lifetime warranty program is JOKE. You basically have to pay for the defective part a 2nd time to replace it and all they do when they get the part back is give you a in store credit. I will NEVER USE THIS COMPANY AGAIN!

superb as always i have been using ECS for years and they always deliver quick and a very friendly staff. I have never had an issue with any orders and all the parts were as described.
