I am with @kenny_h on the rain. I have had my SS swap ends at 35mph and my foot OFF of the gas pedal...
You all can't say I didn't warn you. I know there are 100 stories about how someone drove in a pouring rain and everything was fine. But there are 20 stories where the SS has decided to go on a path of its own. Sometimes it results in plowing up a field or hitting a guard rail.
Please drop the speed down to 30 or so and find something else to do if you get caught in the rain....
And remember if you hydroplane you are at fault, ticketed for losing control and open for lawsuits.
