Summit Racing gets an A+ rating from me.
For me being located in Ontario,Canada, buying stuff from the States is usually a big expensive hassle with import and brokerage fees and not to mention the exchange rate either. That deal that looks good usually ends up costing the same or more than I could have gotten the same thing here for.
However, I just bought a set of rims online from Summit Racing and their customer service is fantastic. I goofed and orderd 15x7 rims instead of 15x8's and realized my mistake and called them back shortly after and changed my order and they billed me accordingly and phoned me within an hour to confirm all my info.
The deal was done on a Saturday with the wheels being shipped out on Monday through ground UPS shipping,costing me $83.
Amazingly,it only took 3 days for them to arrive! Usually I have to wait over a week before I see my items I order from the states.
Great company to deal with and friendly service. Don't hesitate to deal with them, I am extremely impressed with their service and quick shipping.
