Unlikely at best. I've seen a few pieces of gear at track stores, but never full setups, and usually very expensive. The gear on the lemon's website isn't actually stocked by Lemons, they just forward the orders off to pyrotect, so none of the gear is trucked around race to race.
The other issue you have is the database for the race is closed. Adding you as a driver now, or at the track, will cost a lot. Unlikely a team will want to go through the headache for an unproven new driver without gear.
