Someone tell me how I ran a 1:34.6 on Laguna Seca in the M4 frozen black...? Completely stock sport hard... Can't change anything on the car but the tires anyways. Production car lap record is held by a 3200lb 600hp SRT Ta.... But yet a 430 something hp probably around 3800lb car comes that close... Like I said In my earlier post there was a reason they took the car away, the physics are off. Just for reference even more, a gt-r black runs a 1:36, sls amg black runs a 1:35, 458 and lfa both run 1:36. A near 700hp aventador only runs 1:35 on this track. Humm.... Come on gt. Now I'm gonna run the normal m4 in the dealer to see what it runs. I also put ss on the m4 and ran a 1:31.3. The SRT ta I believe rant that with racing slicks.
