5 male and outer end M16x1

This unique Corvette C6 rack offset spacer kit will help to achieve even bigger steering angle on C6 chassis (not needed on C5) and improves Ackermann curve on Wisefab PRO level drift angle kit

Ackermann and bump-steer have also been revised for a more refined driving feel

This means that OEM wheels can not be used
