Tesla Roadster (2008-2012) Front and Rear Wishbone Bush - PF34-1001BLK The PF34-1001BLK fits all positions on the Front and Rear wishbones except for the Rear Lower Front Bush which uses PFR34-1002BLK. This part provides an extra 25% stiffness over our previous offerings, reducing distortion and improving wishbone control whilst retaining compliance. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
