FAQS

What’s the advantage of the slip in collars?

The slip in collars sit above and below your standard subframe bushes and essentially compact them. This results in less movement of the subframe and eliminates axle tramp and increases stiffness in the rear of the vehicle.

How hard are these to install?

Installation is pretty straight forward and the slip in collars are as the name suggests, slip in. Installation shouldn’t take you longer than 45 minutes - 1 hour.

Is there a noticeable difference in the feel of the car when driving around normally? Ie. any vibrations?

If you don't already have coilovers and other noisy parts then you will notice an increase in NVH however if you're running coilovers, there's no notable difference
