The Vehicle Modifications Form  serves to ensure that any  modifications to the vehicle's original equipment will not interfere with the wheel's performance or safety. We recommend that this process be completed if after market parts have been fitted to the vehicles suspension, including: brake calipers, lowered suspension platforms, lowered springs, modified stud patterns, modified stub axles etc. If you are uncertain of the extend of your vehicle modifications we suggest that the form be completed. Once you've submitted the form we'll get back to you, or if you don't need to, contact us free phone and we'll do the rest - Having difficulties?  talk to the experts 0800 624 626 (with in NZ only).
