I learned this a few years ago when I was bouncing between the track and rallycrosses with my mr2. I'm not sure who else does it but Firestone has a lifetime alignment you can purchase. I basically told them before I purchased it that I would be coming in a LOT because I tracked the car. They said bring it.
Warning, BTW, my car also requires a 4 wheel alignment. I had done 2 alignments and on the third found that the shop here in Melbourne had a new owner. On the third visit they said that they could not do the rear because my car was too low, I think, sorry it's been a while. Not to drag this on but I had it out with them, even had to go to the Better Business Bureau. The result is I have to drive to Palm Bay now. Oh well. Just make sure you discuss it with them beforehand.
I don't know what other guys do but I thought it was worth the money.
