So I just bought a used S60 and need to swap out gears and buy new outer bearings. First off, what kind and where can I buy the outer bearings for this? Second, what brand, kind, and where can I buy 373 gears for this that can withstand a 150-200 shot off the line? My car is street driven with occassional trips to the track. Help me out guys I want to order these ASAP since the rearend is currently in shipping heading my way. It's going in the car as soon as it arrives along with the whole rear suspension. Advice greatly needed!

Experiences with certain brands of these gears would really be appreciated!
