Hub Centric Design: with Lip fit tightly to the hub & wheel to reduce any type of vibration or false reading.
Machine-Forged precisely from 6061-T6 aircraft-grade aluminium billet, with heat-treated and hardened 12.9 grade bolts pre-installed. The anodized surface provides additional resistance to corrosion. Extraordinarily strong and light compared to spacers made of steel.

We recommend customers start threading the hardware on by hand so as to not cross thread or strip the threads. Once secured hand tight, use the torque wrench set to the proper torque. Tighten the wheel bolts/lug nuts one after the other in a criss-cross pattern(as show in the sixth photo). Make Sure You Get 5-7 Turns Before Tightening. Suggested To Be Torqued Down By Hand At 85 FT/LBS.
Under- or over-tightening wheel-attaching hardware can be damaging and dangerous. When the lug nuts are over-torqued, this could cause stress fractures and increasing the risks of the lugs breaking under normal conditions.
If no problems (noise, vibration, anything out of the ordinary), Re-torque all lug nuts after 5-25 miles of driving.

Situation and solution of installation Failed:
If your Center bore height is more than the spacer, it means you will either have to go with spacer without hub centric lip OR use thicker spacer. As our hub centric spacer need to have taper to allow the change of center bore size. if you don't check your Center bore height. Inner taper will be in the way. On these spacers if your Center bore height is more than 17mm the installation will fail.

If you are looking to change the PCD of the car to different PCD you will have to make sure the clearance at the back of the wheel allows you to commit this changes. Sometimes if there is a rebate or recess on the back of the wheel, does not mean there is enough clearance, usually if the stud pattern is changed dramatically (eg. 5x100 to 5x120) then there might be an issue.

If your car uses lug nuts (stud extrude from hub to tighten wheel down), you will need to know that if your studs is protruding out by 28mm and you are buying 15mm spacer, you will have 13mm extrusion from the surface of the spacer which might stop the wheels from sitting flat against the spacer. Thus if you get 30mm spacer, you definitely don't have to grind anything for sure.
