You'd be correct in that thinking. However, if the drivetrain is already loaded, as it is in an automatic car ( even at idle ), you're a lot less likely to break stuff than if you shock the drivetrain suddenly ( as in a M6 car ).

If an automatic car can hook on a radial, it's what you should use. If not, do some suspension tuning or go with a bias-ply.

 

Right it seems like the poster was worried about breaking his 10 bolt on slicks with an auto. I run bias ply on all my stick cars and my A4 is on a radial.

 

I'm currently at 437rwhp. I'm running a FTI 3600 converter, 3.73 gears, BFG drag radials, stock 10 bolt, and going to the track tomorrow (weather pending).

I'll let you know how it goes...

 

Damn you auto guys My 10bolt said 'fuckyou' on my 4th launch lol
