I have the street bushings for what its worth
Honestly for the amount of labor involved in making the switch I feel like its a buy once cry once scenario. Unless you are seeing tons of great reviews on the cheapest kit I would spend the extra money for a known quality.
Also lifetime warranty...
i hear you on getting old man, my left bicep still gives me the occasional twinge from some suspension work a month ago.......
i guess its better than being dead
