Imo, the challenger is the worst choice an m3 driver could make. Way too mushy of suspension, I feel like it's set up to be an american luxury/muscle car. I like the boss 302 and newer shelbys better. I recently ran some type of hennesey challenger, didn't get a chance to ask him which specific kit it was. I think it was the base model which equates to 550 to 600 crank hp. My car weighs around 3500 and is FBO with a dct. I beat him twice by a length and he got me on the 3rd by a half. They're very heavy, the stock 2013 srt8 is 4170 pounds! Boss 302: 3631 21013 shelby: 3850 z06: 3199
I want to eventually get a z06 in addition to my m3. I'm not in love with the interior or exterior of the car, but the performance can't be denied. With the c7 coming out soon, I'm hoping the c6 z becomes even more affordable used. Right now a nice low mileage car can be had for low 40s. And they are very easy to turn into monsters, many parts are also cheap compared to our m3s.
