I've been doing business professionally with Summit Racing for the better part of a decade. They're an industry leader in direct to retail automotive aftermarket parts. My personal relationship with summit dates back to the late 90's as a high schooler who listed after hotrod parts for my car.
Their business model is simple. Have it in stock and provide exceptional customer service. They do both very well. They have three locations nationwide. One in Atlanta, one in Reno and home base here in Ohio.
Kudus for years of exceptional business practices. Keep on keepin on.
