Default Low RPM Rumbling - Chattering - Bogging

Hi,
I have such a hard time getting consistently smooth starts into first with my car (951S).

In normal street trafffic, I find I have to rev to about 2800 rpm, then slowly release the clutch while really committing a good amount of throttle increase to get it going smoothly. Otherwise the transmission gets bogged down, chatters ect.. It's really hard to do this in the confines of regular street driving in towns with significant traffic.

Thia drives me crazy, anyone else?

It goes in lower rpm, just not consistently smooth like my bmw.

It feels like the car just prefers open roads and race tracks to city driving.

I went into Manhattan yesterday, it was BRUTAL.

Do you have a Light Weight Flywheel?

Is you E-Brake Sticking?? <-- Seems Likely; Raise the Rear-end of the car and try to turn wheels in Neutral...

have you gained a lot of weight recently...? Ha ha
