I can't say enough about the great experience I had buying from Mad Racing! Great prices, quality items, very knowledgeable, fast shipping, and even added a unexpected treat in the box! They will definitely be on my list for future business!

What a great service. Pick out your parts, get them shipped to your door, fit and cut every to length and send them back. Wait a few days and you get a box of professionally crimped lines that you did yourself. Thank you!

Great service .give me respons on the sending of the parts. And good quality.

Super fast shipping and great price !!!!

This fits my P3 port perfectly.

My Holley USB cable was not properly crimped on one wire. This connector kit allowed me to restore it, so my communication is reliable again. Easy to install if you have crimpers for very small uninsulated terminals.

Phenomenal knowledge. Aways has what I need or within a couple days, can't be his pricing.

Speedy delivery, quality product that worked as designed. Thank you!

Scheduled hub dyno session to address issues with shifting/engine miss. Was able to resolve issues quickly with Glenn’s help and parts. Very happy with the service 👍

My third or fourth sensor bought from Mad Racing. Great price compared to the one from Holley, and they have been working flawlessly. Always a pleasure to deal with Mad Racing.
