Tuner Installation Kits

Installation Instructions

Tuner Cone Seat Lug Bolts, also called acorn or tapered seat, are desinged to fit small diameter recesses in Alloy Tuner Wheels for vehicles that require lug bolts as opposed to lug nuts, and wheels with a cone seat. It is extremely important to install the correct length lug bolt with the correct seat. These type of lug bolts have a 60° taper.


Tuner Style Lug Nuts are designed to fit small diameter recesses in Aftermarket Alloy Tuner Wheels that require a cone seat fitment. This type of lug nut has a 60° taper and should be torqued by hand only.


Open End Tuner Style Lug Nuts are designed to fit small diameter recesses in Alloy Tuner Wheels that require a cone seat fitment which have a centre cap covering the lug nuts. This type of lug nut has a 60° taper and should be torqued by hand only.
