before I took "Emma" to RUF and got the Nardo package...I took off the AWD shaft... pushing 520 BHP then, my 1/4 was in the low 11s in thte 1/4, but the car becomes unrulingly unstable if you want to track it! I did the GT2 brakes and all that stuff with the PSM...my suggestion...GET A GT2 or take it to a good tuner...

 

I try it. If you don't like get a GT2.
