Hardrace Roll-Center Adjusters are special CNC machined spacers to correct the roll centre on lowered cars. This relieves some of the angle on the driveshaft CV joints and will prolong CV joint life - this is why we call it the Driveshaft Saver. Driveshafts are a common fault with P1 chassis cars and it is easy to see why - there are tons of lowered cars! Even a drop of 50mm can wear driveshafts quickly and they are not cheap to replace.
By installing the Hardrace Roll-Center Adjusters, it will correct the suspension geometry of a lowered car, putting the control arms back closer to its original position, resulting in increased steering response and stability while eliminating bump steer.
- Decrease roll
- Improves tire contact patch with the road
- Increases steering wheel responsiveness
- Enables increased cornering force
- Prolong driveshaft life
The OEM Tie Rod Ends will have to be adjusted to compensate your steering angle for the new ball joints. They will toe in without adjustment. Adjusting the OEM Tie Rod ends may result in the Tie Rod End only being attached by a few threads.
Fitment Notes: Hardened Rubber. Tie Rod Ends not included. Ball Joints Not Included as standard. Ball Joint size depends on chassis number. Check the last 6 digits on your VIN code, that will be the chassis number.
