Great fitment, prices, and the video instructions make install a lot easier. Shipping is always quick, and you get a sucker! Hope they do more r&d so that I can buy from them again..

Ryan was amazing. Easy to work with. The quality of products are exceptional! I will definitely be coming back for some additional goodies.

Great product and great customer service. Charge pipe was very well constructed. Had to make slight modifications to get the fitment right but fit and works as intended.

Great costumer service and fast response!

Ordered the upgraded aluminum charge pipe for my 09 335i. Fast shipping and great packaging.. quality part too! Install was interesting, you do have to relocate the power steering reservoir to make room but once it's all together it looks beautiful!

I ordered the N54 FBO Kit and the quality of the parts is top notch. Had some concerns and called customer support, Ryan (Customer Support/Sales Manager) was able to provide 5 Star service both over the phone and email. Shipping to Canada was quick and came early. Couldn’t recommend ARM more.

It was great

Customer service is top-notch. I ordered the catted DP for my 2015 GTI during Black Friday sales and it arrived 2days earlier than originally announced. I had the fmic sitting in my cart and Mr. Ryan took any step possible to ensure that I would be happy moving forward. I'm almost done with my build, but I promise I will be a returning customer.
