Hey guys, I've heard a lot of great things about gears and how much they liven up the car (not that the car lacks power, it spins the tires in 1st all the time). But I was wondering, how difficult are these to install? I have experience installing various bolt-ons, but haven't really had experience with gears/suspension. Another thing, how much do they cost? And if it is too difficult a job for me to do on my own, how much would it cost for parts+labor? Thanks for any help.
