Dear E34 owners,I thought i'd share something with my fellow forumers.I recently installed a set of PowerFlex poly bushings for:1) Front Upper Control arms2) Rear Lower Control arms2) Rear Subframe BushingsFindings:1) Initial Turn-In is MUCH sharper. 2) Rear of the car feels so much more planted during kickdowns, especially midcorner. 3) Overall chassis feedback has improved. Car really tells u where its going4) Ride Quality is more solid especially over bumps and uneven roads You can feel the car soaking up all the uneven bits. Conclusion:Rear Subframe BushWhen comparing stock rubber bush and the powerflex, the stock one has gaps which allow for lateral movement (must be to reduce harshness) whilst the powerflex is completely solid and sits flush between the subframe & chassis and mounting plate with zero lateral play.Initially i thought i'd have more vibration & harshness being transmitted from the rear wheels to the chassis. But surprisingly this was not the case -Instead, the rear feels more solid & composed when going over bumps - Must be less subframe movement and more work for the suspensionFront Control Arm BushAgain, when comparing the stock rubber bush and the powerflex, the stock polyflex is actually larger and literally fills the gap between the arm and the mounting eliminating any free play during hard braking or cornering. Like the rear, the front feels more composed over bumps and undulations. The steering feedback is truly amazing as i can really feel what the front & back are doing which in turn means its much easier to set the car up for a corner.Overall, i'm very happy with the handling improvement for my old bird. In retrospect, I always thought that i'd end up with a harsher ride due the inherent nature of solid bushes. But in my case even with the 18inch wheels - all seems pretty composed.The question is......let's see how long it lasts!
