The X2 Link won't work since only one track on the schedule has the base antenna system installed, and Lemons uses the old TranX/X2 Loop encoder system, and really it doesn't do much over the basic transponder's job except cost more for the subscription. (but no more digging a pit across the race track.)
The regular X2 Transponder will work. But only buy if you will be racing more than 3x a year otherwise wasted money on the annual subscription.
There are ways to get Position and data out of your car through smart phone rigs, OR if your Arduino-FU is strong, via home brewed means.
