Driveshaft Hex

[rfulcher]

Can anyone explain what the difference is between the TKR5571A & TKR1654X? I really hate the plastic ones that came with the car and was not sure which one to get.

the TKR1654X is a +1mm offset which widens the track width, more info here on what that does:

I have generally found that the stock hexes work best for me, the +1mm hexes seemed to slow my car down too much and lost performance in my lap times
