Ditto to what Aumoor said. I've never had a Lonestar, but get it away from the "Toys R us" crowd at the local tire shops. Find someone that knows what the score is. (I did via my local SCCA club).
I found that after one of my sessions from a local Firestone the guy was trying to adjust it the wrong way. He told me I had a bent frame! After I found the sports car shop owned by a racer did I find that he was all wet behind the ears. The car handled like a dream after that. (I found the car had bumpsteer, and I didn't even know what it was then).
Anyone that tells you there is no castor adjustment probably would also tell you there is no device on a flush toilet to make it flush.
