I remember fitting my flo-flex. opening the packaging to see the product in cheap zip tie bags was the start. Once i inspected each bush I found the front and rear anti roll bar bushes needed cutting to fit. Powerflex cut theirs from manufacturing. The rear wishbones to hub didn't fit correctly, upon fitting the roadwheels you can rock them side to side. MOT failure, so pulled them out and fi powerflex. All 4 bump stops are powerflex front A/R is powerflex. Was just a matter of removing and binning.
