Well here's a decription of my two runs
This was my first time ever on the strip with the cobra, now with new
slicks I had no idea how I was going to launch, with my other tyres it just fries them so I took off pretty soft in the first run and boy did they grip 12.238 at 116.3 mph
So on the second run I gave it a bit more, actually a lot more hehehe
and it broke traction ran a 12.404 at 118.43 mph
Like you said guys there's a bit practice, trial and error to get a good run
and in a way I'm glad I didnt go faster than 12sec, It would have been get a roll cage for me too from the officials.
Have a look at my first run this is awsome
