@ 4.10 in first vid, did you take the optimum line?

The front wheels block without ABS, does not make it easier to hold the optimum line.

Side 11, Number 5.

"Whether 24-hour race or endurance championship: On demanding section Wehrseifen are always very many fans - mostly not for nothing, because many misjudge here with the Pace and end up in the tough little wall on the boundary curve.

Before the turn- it goes back on the gas and the car compasses very closely along the curb by the continuous outward Curve. The processes have to fit perfectly - who even when turning on the brake, or in which Curve of gas every day have a bad hand: The Car is instantly uneasy, there is little space to correct. Because of the kink at the following left Wehrseifen closes extreme, the driver gets in the usually far from steers and very late to the left - preferably in third gear, which saves a switching operation in the lateral acceleration phase at the output. Before the start of the sharp line of battle, be warned, because the slope falls on the inside like a ramp down - there are all the wheels when braking quickly. Understeer is the output of Wehrseifen poison - but unfortunately there under control almost all the cars! So always take into account some slack and not too fast in the tight bend into thunder. Caution: The right to swing at the output of the passage in the direction Breidscheid is tricky in the wet slippery!"

Goolge translate?! :? Sorry, but I struggled with with the crucial parts of that - "the driver gets in the usually far from steers and very late to the left - preferably in third gear, which saves a switching operation in the lateral acceleration phase at the output. " LOL :D

...but yes, I could hear the tyres...that's why I asked the question. It seemed the me that you could use the camber more in your favour?

I'm Not, trying to be smart - what do I know?! I've only done 3 laps in torrential rain and mist on A048s (sans chapeau ;) ), prob 20.0 btg :D

The curve to the left is extreme, the driver must drive far to the right and steer left late, the best in third gear. At the exit of the corner you will then save a switching operation. :unsure:

Front 50-80 N/mm (progressiv)
Rear 85 N/mm (linear)

Standard ARB with teflon bearings.

I am absolutely satisfied, performance is sufficient for me.

Original Porsche parts. Cost only a few euros and must be adapted and modified slightly.

Test the new RSR at the Circuit Zandvoort. Cold pressure 1,55 bar front and 1,65 bar rear, hot pressure 1,95 und 2,1.

The RSR also worked very well after a session of 45 minutes. High level of grip, in my opinion a very good tire for the price.

My guess is on battery plus pole hitting the chassis.

(I had the same)

This is the lamp of the brake fluid reservoir.

 

The lamp lights only on the race track after I replaced the cap. The Reservoir is full enough. I'm going to check the connection.
