[iManu]

Hello, I have a x3m40i, in posting here since there's more 340i than x3.

I got new tires, Michelin 4s and now when I launch my car around 3000rpm, I get zero wheel spin.

After a few launches, I heard a clunk noise and then found out that I had a broken left rear suspension tab and the rear right drive shaft was torn.

Anyone ever break any parts by using launch control on a modded or stock car?

Should this be covered under warranty?

I run 265 in the rear and 255 in front.
