12.7 @109 on Street Tires

italy3541 · 05-30-2015, 02:29 PM

So I finally got the Z4 to the track today. It was hot as hell out but I wanted to see what it could do. 12.7 was the best for the day. I could not get any traction off the line so I had to launch at idle. Any higher and I would just sit and spin I need a LSD bad... I know with slicks or LSD I could be in the very low 12's. Not to bad for just a Dinan tune FMIC and intake.

That's an impressive time for street tires and only a tune!

Thanks. I know I can do a lot better with more traction. I had to baby it so much off the line. I was not full throttle until past the 60 foot mark. The car had so much more it could do.

nice time! yeah if you can get that 60ft to a 1.8 you should be in the low 12's.
