I am considering purchasing the PST front end kit and have two questions:

1) I am wondering what the longevity is like for the rubber bushing kit? Im assuming that the rebuild process is quite lengthly, and dont want to have to perform this task every few years....

2) What are your recommendations from a performance standpoint? Rubber or polygraphite???

 

I bought the poly kit, two years ago.... Still going strong... Tightened up the front end....
As far as installation, I had a shop do it.....

 

I considered their poly kit before I went with the Energy Suspension poly setup. Their Customer Service turned me off. I called to ask what brand ball joints were included in the kit as I wanted to ensure they were quality parts (like Moog). The rep told me it was proprietary info and wouldn't share the brand. I proceeded to buy the ES poly bushing and Moog ball joints from Summit Racing. I am happy with the results...tight and no squeeks.
