Congrats on your new M3 convertible. I had a 2011 E93 M3 before I bought my new E92 M3. What I liked best about the E93 was no wheel-spin, I could just floor it. With the E92 I'm trying to figure out how wide a tire I can put on my 19 inch CSL rims because, right now, my standard launch is spin the tires until the DCT prematurely shifts to second gear.
