Moonface Racing Roll Center Adjuster

18 Sep

 

Moonface Racing just released a Roll Center Adjuster for the Z33, so I thought I would take the time to explain what a roll center adjuster does and plug a new product…

Three things happen when you lower your ride (other than it looking much better ­čÖé ). You will:

  • Lower the center of gravity. ┬á
  • Change the suspension geometry that countless Japanese engineers (who also happen to be much smarter than you) had created for the car when it leaves the factory.
  • Lower the roll center that again, came preset by factory┬á

When you lower a car, the distance between the center of gravity and the roll center increases, causing the roll stiffness to decrease, and voila you ended up inducing something you thought you were correcting – body roll. ┬áSure you can mask this with stiffer springs and stiffer sway bars, but this is only a band-aid. ┬áIf this is on your street car, stiffer springs also means a harsher ride.

The Moonface Roll Center Adjuster will raise the roll center up (without affecting the ride height) and bring the suspension geometry back into factory spec. ┬áThis decreases the distance between the center of gravity and the roll center and as a result, drum roll please … less body roll.

Another byproduct of correcting the suspension geometry, is that you will increase turn-in speeds and reduce bumpsteer. Which if you don’t know … are good things.

Wow that sounds great, Shaun – where can I buy it? Good question reader, right here┬á
