Hi,
I completed the install of the Z0k front and rear stabilizer on my 2008 GXP with Polyurethane bushings from Engergy suspension as well. I order the red ones (front and rear) from Jegs. The front were the Mustang bushings (34mm). This came in a box with the bushings and two tubes of grease. The bushings didn't come with a bracket or a bracket with a nipple so I used the stock GXP brackets from the old bushings. They worked fine, the fit was good. I used a tube for each side and if it starts to squeak I'll just crawl under the car an pull them off and regrease. I can check them whenever I do an oil change.
It was a pretty easy install. I had the front on rhino ramps and crawled under (incidentally, does anyone else like relaxing under the car? It's rather peaceful) undid everything and reinstalled in reverse.
The back was more of a pain in the a$$ but it only took an hour. Figured it would take longer.
I jacked up the car, put it on jack stands, pulled off the wheels. After undoing the brackets etc. I found it was a real pain to snake the bar out. I have a RCD solo exhaust and found I had to undo the back muffler bracket rubber and slide the stab bar to the back then out one side.
In order to reinstall I had to jack up one wheel to clear the axle. Not sure why, but it worked. I bolted everything up with Poly bushings. These ones came from jegs with greasable brackets, and a hole in the bushing for the grease to pass.
Everything worked fine.
Took her out for a quick spin before storing her away. Boy it very hugs the road. I didn't think it would make a difference but it was ROCK SOLID! It was worth the $260 spent for both bars. Takes the curvies really good.
I like.
