This kit includes a pair of components that bolt to Honda rear trailing arms and alter the mounting position of the rear lower control arm for the purpose of correcting the rear roll centre height.
Why do 1988-2001 front-wheel drive Hondas benefit from Roll Centre Correction?
These cars have a compromised version of double wishbone suspension, referred to as Short-Long Arm. In these chassis, the upper control arms are relatively short, particularly the rear camber arms. This is different to say a Miata (MX-5), which has upper and lower wishbones of similar lengths.
This system is superior to a MacPherson strut suspension design for a number of reasons, but one downside is that the roll centre moves vertically down when you lower the car.
In fact, at typical track car ride heights without roll centre correction parts fitted, the roll centre height is only just above the ground plane,. This means that during suspension compression (bump), the front and rear roll centres go below the ground plane, and there is no incline in roll centre axis from the rear-to-front (which is desirable to have).
What our roll centre correction parts do is raise the front and rear roll centres so that they are at what we believe to be the ideal heights at ride height and then don’t go below the ground plane at full bump.
Benefits:
- Improved turn in and chassis response
- Excellent mid-corner adjustability
- Better corner exits as car rotates instead of pushes
These benefits have been quantified by on-track testing and can be visualized by way of the onboard data record.
You can read about our track testing with the roll centre correction geometry kit in this blog post.
Our rear roll centre kit is intended for vehicles that already have front roll centre correction ball joints fitted.
Our geometry correction components are suited to vehicles with a ride height between 295-320mm.
The rear roll centre brackets increase rear roll stiffness. For customers who have tuned their suspension to have high rear roll stiffness by other means, such as high rear spring rates or stiff rear anti-roll bars, we recommend reducing spring and bar rates prior to testing.
We recommend rear spring rates in the range of 5-12kg/mm (300-700lb/in) and soft-to-medium rear anti-roll bars. A DC2R-type 21mm rear swaybar is a good option, or aftermarket swaybars with a soft range of adjustment.
Tools required for installation:
- Angle Grinder (and appropriate PPE)
- Drill and 10mm drill bit
- Torque Wrench
(Optional but handy – die grinder)
For more detail on the installation see the below video.
For heavy-duty use, which we define as:
– Vehicle using Hoosier tyres (treadwear 40) or similar
– 17-18″ rear wheels with 180 treadwear tyres or less
We recommend reinforcing your trailing arm with a weld-on bracket in the lower control arm mounting area.
