Polyurethane replacements for the rear spring pads in PowerFlex's Black Series compound - the stiffest they make, intended for track and competition use. The pads sit between the coil spring and its seat; the factory items are soft rubber that compresses and eventually perishes, letting the spring seat shift and creak.
Black Series removes essentially all of that compliance. On a track car that is what you want: the spring stays exactly where it was put and the rear rate is the rate you chose, not the rate minus bushing squash. On a road car it will transmit more noise than the Road Series.
Features:
- PowerFlex Black Series - the stiffest compound, for track use
- Locates the spring with almost no compliance
- Resists perishing far better than factory rubber
- Cures spring-seat creak
Fitment: Hyundai Veloster N, rear.
Please note: Black Series is a track compound and will pass through more noise and vibration than standard. For a road car choose the Road Series version, PFR26-119, which we list separately.
