Hi bud, I have always fancied giving the polyurethane bushes a try but I always gagged at the price of them! You will have to let me know if they were worth it :P
I can tell you though that if you are changing your track rod ends then you will DEFIANTLY have to get your tracking done ASAP. If you don't then you will soon find yourself needing new tires
GL and let me know how those bushes turn out!
