Start issue

[Jimmy_GTT]

I'm trying to measure 0-100 acceleration with my GTT, but I'm not able to have a good start.
I measure it with AP22 from Race-technology. It starts measuring after a certain G force is reached, so no reaction time delay.
But either the wheels are spinning, and the car would hardly move in 1st gear or there is a lag right after the start.
I think there is something about my clutch. It has a very discrete point of engage and I'm not able to slipp it.
As I remember somebody has written earlier a similar problem with his clutch.

Any help would be appreciated!

I still have this problem.

Either wheelspin or bog donw on start.

No I have all the parts to make the soft pedal conversion. I only have to take the gearbox out. :(

Could it be also a camber, tow in - tow out issue?
I'm runnig on 2 degrees negative camber. But I do not remember the amount of tow out I have.
What should be a correct setting? The car is lowered about 50mm.

Maybe I also have to check the shocks.

Thanks
