Well it’s been awhile since we’ve talked but I just wanted to give you some feedback.  I love the feel of leaving corners now and my major concern of added under steer is not the case at all.  It steers in hard and lays down traction when I need it.

Thanks again for all of your help, such a simple product with unmatchable performance . . . and you can quote me, ha!!!!! Also, I really like your company and what you’re doing and would love a shirt or something to help represent you all.  Let me know if that’s something you can swing, otherwise thanks a ton for your support and quality product!!—-Jason Schmidt
