[QUOTE="Corbic, post: 16377559, member: 171475"] Yes, I've also know plenty of other people who have mistakenly used them. Poly Bushings increase noise, vibration and binding. They make the car ride stiff, you'll get extra chassis whine and they will bind when not greased. They also tear and wear out fast. Like in a year fast. What's the upside? There is none. You won't go faster, handle tighter or see any marked performance improvements. But then why the anecdotic success stories? Changing out 20 year old rotted OEM parts for new ones will have some improvement. People also interpret the harsh, noisy ride as "race car". Best comparison I have is my buddy at Cobb Tuning. They had a BRZ and FRS, one got all the Energy Suspension upgrades, and was markedly slower at a track day event. "Real" race cars use spherical bearings that are rigorously maintained and replaced. The OEM use rubber because they know it will last longer and perform better. If your car is sloppy and loose, replace the aged OEM components. Who do you think knows more about suspension design? OEM designers spending billions and racing teams that need every advantage possible? Or some guys trying to sell you $4 worth of material as $200 bushings? [/QUOTE]
