Nitron are now making available the ultimate upright assembly, for the serious racer, track user or enthusiast. By manufacturing uprights with the hub centre raised by 25mm, the car is effectively lowered by this amount without changing any of the suspension geometry. We have spent months of design time to arrive at the optimum solution of raised hub, overall weight, increased stiffness, cooling efficiency and overall packaging of the front and rear uprights on the S2 cars. The upright itself is internally vented and allows cold air from an intake duct to be pumped around the bearing.

• Aluminium upright 5-axis billet machined in 7075-T6 and HARD ANODISED
• TITANIUM bottom main spindle with rolled threads
• Conical spacers in stainless steel for lower Ti spindle
• M16 nyloc nut for lower Ti spindle
• TITANIUM bottom toe-link spindle with rolled threads
• Conical spacers in stainless steel for toe-link Ti spindle
• M12 K-nut for toe-link Ti spindle
• High tensile electroplated 12.9 grade bearing bolts M12 (specially made)

The rear upright has been designed to accept both the smaller AP 2-pot caliper (originally fitted to the front) or our recommendation of the 4-pot as on the front.
