How much can the GSR axles take? also what are some good axles to get that can handle up to 600 wheel hp as a replacement?

thanks

 

well they sure as hell can't take 600 whp!!!

keep in mind that a larger wheel with a smaller sidewall increases the shock factor on your axles.......and http://www.driveshaftshop.com is a good place to start looking at aftermarket reinforced axles.

you can break stock axles with 250hp if you have a stiff clutch and do stupid hard launches.

with 600hp i am guessing you're running a drag only car so you'll need aftermarket axles to handle those launches.
