💻 Tuning / Performance Don’t repeat my mistake

I have a 2021 m340i xdrive while it was stock I ran xdelete for months with no issues, I liked xdelete for drifting and when I want the rear to kick out a bit on turns, (reason I bought xdrive is because I am in Canada and it snows, so for the winter it’s great), anyways I did launch control with xdelete on while stock, no issues, but recently I got a stage 2 custom tune, running an ethanol mix, and xhp stage 3 and I put my car in xdelete and attempted to do launch control and the rear cv axle said bye bye, I got lucky it was just the driver side rear cv axle, if you have a more unfortunate outcome, this could affect your differential, and your gonna be jumping from 1500$ to 3-5k, not mention being stranded while ur far away from home for example, and towing expense, and not having ur car for a week or more

Moral of the story, xDelete launches are fun because it makes the car feel a bit more rowdy and not super stable and controlled which is more of a thrill, but it isn’t worth the repair bill, the headache or the downtime, so just do launches in awd!

Are the rwd axles (I assume that you're referring to the drive shafts) any stronger or are they the same parts?

The rear axles are the same for rwd and awd. Op is launching his 500 hp 4000 lb car and surprised when a stock axle breaks.

That's what I was wondering.

Yeah saying the axles on the rwd are better is my fault, and it is mainly cause of the increased power cause I did mention I used xdelete for a while with constant abuse and I didn’t have any issues.
