The first thing you will need is rear tires,every thing really depends on you.If you dirt race,rpm arms,rpm front bumper will save you future trouble.If you street race you will want to go for alluminum to gain weight.If your lhs stocks alot of parts,just wait and see what you are breaking.I have had mine since they first came out and have never broke a rear shock tower,but countless a-arms have found the trash can.Imex is coming out with 2.8 tires,2.2 wheels & tires will fit.IMO the jato eats tires so fast,I don't buy fancy rims,good old traxxas white dish rims work fine for me.I have the 3.3 engine,cvec pipe,sway bars,mid mount receiver pack,aluminum a arms,rpm front bumper 60mph+++++.
