THE A.E hex conversion is a must. Great upgrade over stock, my bearings are always lost and come out of the wheels, this is much nicer and tighter. Plus if the shop only has rb5 or 22 fronts u can use those. Its better for hobby shop and you.

will change the rear over soon after i wear threw my sets of tires.

My tire collection is massive, i started with a set of fronts and rear, in a month i have 20 sets of tires. Its nice racing inside

Anybody using the proline front hex ? I can get some from track they look nice also
