aye aye, no, IP
For those of you following along at home, this will be my third season racing with the POC. I have an STS license (the entry-level race series), and will (hopefully) get signed off on my TT license this weekend. Cars are classified by year and other details using a two letter system. The first letter usually refers to a group of years of make (centered around engine size/hp). I'm "I", which fits with my '79 911SC (US-spec). The second letter refers to the amount of modifications: S is stock (very few mods), I is improved (a few more mods), P is prepared (still more mods).
There is a fairly large jump in cost and lap times between I and P. I've been running II class, as I have minimal modifications to my car. I've been sucessful in II, last season finishing 3rd in the first race, 2nd in the ssecond race, then first for races 3-8. I also set a couple of class records for the track :-)
But as luck would have it I had some pretty bad oil leaks and needed a new clutch...so in the pursuit of "while you're in there", I made a couple of modifications to my car that bump me to IP. I could probably "fake it" as they are not readily apparent, but I want to be on the up-and-up. And have the satisfaction (in the event I win) that I'm totally legal. So there you go...I'm a bit further down the slippery slope. The downside is that now a couple more modifications are legal, so I can spend even more money on my car. Oh joy. Oh rapture.
