rear end build

[krhonn]

At what power level are you manual guys/gals beefing up your rear ends? Welding axle tubes, different axles and so on?

IMHO, it's more the tire than the power level. Upgrade your components if going with a slick or sticky drag radial at the track. Spinning street tires don't load the rear end that much.
