I did a driver's education event with the Alfa at PIR in Oct 2002 prior to turning my car into a full SCCA T1 racecar. Had a blast... which contributed to my deciding to go racing.
I think track experience is beneficial to all as it will make you a better driver. But, please be careful out there. The speeds are high, there are concrete walls, etc.
In the SSR, I would drive well within your limits. It is a truck. I was at a DE at Roebling Road in Savannah GA in the fall of 2001 with the BMW club and watched a beautiful 530i get sideways and spin to the inside of the track. He went off at about 50 mph or so and his tires dug into the soft earth and he did a full slow speed roll. Ouch. I knew the driver and instructor would be fine (and they were), but the car was a mess. He got every single body panel, both front and rear window and the roof. It was not good for me as I had brought my wife to show her how safe DEs were. :nono
I would think the SSR would be susceptible to the same type of problem if you get sideways and go off track.
As a track, PIR is a good one. Be careful on the back straight and coming onto the main straight as there is lots of concrete around. At the end of the straight there is a nice chicane followed by several moderate speed turns with not much to hit nearby. In my car it is safer to go faster on that part of the track given the very low COG.
Be mindful of these things:
- Tire pressures and wear
- Brake fade and fluid boiling
- Oil and tranny temp
I doubt the SSR is designed for sustained high speed, high rpm use with repeated braking applications.
If you go, have a great time! :cheers
