Nick,
First thing I would suggest is coming to the Colorado Sprint Championship powered by SKUSA at Grand Junction Motorsport Park this weekend. You can talk with other racers and shops. This is important to making a good decision. Because, the underlying fact about equipment in racing is what shop provides the level of support for their product that makes you comfortable. Its not like buying a baseball glove at Wally World.
And obviously if they are at races in or near your area that goes a long way to figuring our who has the support you desire.
