Short hub boss kits


Recommended Posts

Hi Fellas.

                Looking to see if anyone has any Shorter style boss hub/kit recommendations. 

Looking at the NRG Option but cannot find an exact measurement I'm looking for on there website. ie - Bottom of wheel nut to actual wheel face. 

Currently have some generic Autotechnica one that sits around 45mm from Bottom of nut to wheel face. 

Hoping to gain around 20-25mm of space between seat back and wheel. Cannot move seat further back as rollcage hoop is restricting that. 

I'm aware I could also go for a straighter wheel option if required. 

Any info would be a great help. 


Cheers Mick.

G'day Mick,

I use a HKB boss kit and the distance between the bottom of the nut (the side that touches the boss) and the outside face of my Nardi wheel is ~26mm. The whole boss is ~55mm wide. Looking at some Google images of the Autotechnica boss kits they look pretty tall.

I hope that helps.
