I don't think some folks on here realize just how off-putting all this negative talk is for a new racer...
Andy, and all new or prospective SM racers, we do get it. But is it worse than jumping in blind only to learn the hard (and expensive) way that you made the wrong choice of car to suit your short and long-term goals?
Keep in mind that this class is so close that we are debating minutia relative to issues in other classes. A well driven 1.6 can beat any comparably prepared SM of any year if
you are just a tic better than the other guy.
So whether you are in a basic build with minimal engine work or a perfect 10/10ths build, the biggest difference between cars at the same level is usually the driver. That's very hard to know for certain until you get to the front where there is more consistency and fewer/smaller mistakes, but even there things are really close. No one generation of car has enough inherent advantage to walk the rest so at most tracks you can at least be in the hunt. The question is whether an equally prepped and driven 1.6 ultimately falls a little short by getting checked up in the corners and losing momentum without the torque to recover, or slows a bit more than the others due to heat related issues (IAT, HLAs), etc.
So all this talk is not BS by any means, but it really isn't discernible until you get near the front for the simple reason that even a little farther back the differences in prep and driving completely overshadow the things we are discussing.
That's not to say this is important only for the front runners. When it comes to following the rules I hate it when someone dismisses a racer's concerns with something like "unless you are within a few tenths of the front it doesn't matter anyway". We need a level playing field for cars of equal prep and drivers of equal talent. But the truth is, if you are struggling in the middle of the pack there is a lot more to be found in better basic car prep and/or driving than anything we debate about in terms of parity. Even if that mid-pack VVT always kicks your butt out of a slow corner just like the guys up front complain about, chances are he wouldn't be ahead in the first place if your car was equally prepared and you were getting the most out of it.
In other words, any car you pick can be really, really close. If you want to learn to race and be confident that you will be able to beat anybody you can significantly out-drive, then any year SM will do. If you intend to build a fully prepped car and compete for wins at the Majors, it will be difficult to "significantly out-drive" ALL of the guys near the front, so the 1.6 may not currently be your best weapon at most tracks.
So unless there are at lest a few guys with a 1.6 who really think they have the level of prep and talent to compete, why all the fuss? I suppose, because no matter how much room there is for other improvements in our program, nobody likes to start out with a rules disadvantage or lose a single position because of it.
