The final round of the Texas Sprint Racing Series is in the books and we want to thank all of our great customers who have come by throughout the year to purchase parts and hang out with us. We love nothing more than taking care of racers and ensuring they have the parts they need to stay on track and in front of the pack whether they are under our tent, with another team or a privateer. Congratulations to all of this years champions, vice champions and all of the podium finishers at this round!

The racers who joined us under the tent just didn't have luck on their side this weekend. Despite all 6 racers showing top 10 pace throughout the weekend a tough qualifying set them all back making for a difficult weekend involving a lot of adversity trying to make their way through the mid pack. They all stayed determined and did their best, which is all you can ask for during a weekend like this. We want to thank all of them for their support and we look forward to our next event, the DFW Triple Crown at Oklahoma Motorsports Complex in a couple of weeks!
