Sloth,
Glad you made it home safe. Imagine what the ride home would have been like in the rain before the Bulladelah by pass went in.
We are running the same tires so would be interested to know what pressures you are running. Iam currently around 25 psi but think I may need to be lower.
Are you running a rear stabiliser bar as well as front? You may need to disconnect these in the rain.
Those Falkans look like they would move water pretty good so maybe ita a matter of getting the tire pressures and suspension set up.
A mate of mine is running Continentals on an Audi and reckons they are sensational in the rain. Not sure if sizes available for Cobra though.
How you go in the show and shine.
Have fun
Phil
