I know this isnt really performance but i didnt feel it was good enough to be its own thread. I took my stock burb offroading tonight just some small trails. and by small i mean really really narrow quad trails. I have no idea how i fit through them. Not much mud just some hill climbs and loose gravel/sand. Its not easy to turn that thing around in the woods either, especially at night. My only complaint in the lack of clearance, but i felt it did well for a 12 year old vehicle with 187,000 miles on it.
