Reply to "PI Suspension upgrade or Stock Suspension"

I have poly bushings and really like them. They maintain more accurate steering and suspension geometry under load and over time, make your steering more responsive, and provide better feedback and feel of the road surface. For smooth roads and performance driving they are superior to rubber.

For ordinary street driving, they will accentaute rough roads, translate somewhat more shock to your mounts, and will tend to signifcantly increase road noise.

I've seen several styles. The best are graphite impregnated and are molded onto a hex insert to prevent slippage on the internal bushing. It's a good idea to add grease zerks to each bushing location on the A-Arms while your replacing them.
