jr2 and jr3 help for Jasper, FL

I know people are so skeptical about helping folks, although I have found great people on here. I'm taking my two boys to run Jr2 and J3 at Jasper during the World 100. My Jr2 is on a 13 Triton and my Jr3 is on a 18 Recon. I'm just looking for suggestions of any type. Tires, set up etc. If you don't want to respond on here please message me. I'm open to anything, they each have 1 full year of racing. My Jr3 driver has raced Crossroads twice and my Jr2 once.

Thanks for anything you have offer.
