Quick thoughts on this format.
I'll be honest (see my status). Going in a conga-line is not my idea of fun.
Theoretically, I like the concept. Ideally (at least in my mind) suspension/downforce tuning should be used to make sure people can go through corners with the same speed, and then HP should be adjusted to make sure target lap times are hit.
After that it will be more about close racing.
That would be too much tuning to make sure cornering speeds are close.
So in the interim, I'd suggest constraining drive-train type (or just say no AWD, or AWD only), and apart from overall lap time suggest being not more than 2-3 tenths apart on sector times from a benchmark in a car most people like.
That should make sure cornering speeds are fairly close.
Sorry for the double post. Thanks for the input DSG, always good to get a fresh set of eyes on things to see where we can improve. Two things:
First, I agree in theory with what you propose you are absolutely right that if we were able to more equalize things in the corners it would make for even closer racing. Problem is most of us are too busy to test, tune, test, tune, test tune, etc. measuring our cornering speeds, comparing cornering speeds and then fine tuning HP to get a certain lap time. Most GT5'ers aren't great tuners so they'd probably just end up going from car to car to car to get the right cornering speeds and it would take much longer than it does now. We're already fielding concerns about how much time it takes to qualify a car which is why we came up with this [post=7862910]Really BIG Announcement[/post] in an effort to streamline things and cut down the time it takes to qualify cars. What you propose would indeed produce even closer racing, but at the cost of quite a bit more time on the part of just about everyone in the group, time I don't think they are willing to spend.
Second, I can only speak for myself, but I really enjoy the challenge of trying to get past guys that run different speeds than me in the corners and on the straights, all the while knowing that their lap time will be the same as mine. It often means setting up passes for a lap or two ahead, hunting out weaknesses in other cars and drivers, pressuring other racers to make a mistake so you can slip by in a place that will allow you to complete the pass. For me the focus is entirely on my and their racecraft, and I get more satisfaction with my 3-3rd place finishes than I would with three runaway wins in a race series.
For me each challenge is different. I know when I'm behind NC for example, based on the last couple of weeks, we are relatively the same pace and he makes very few mistakes, usually none. For us it might as well be a spec race we are that close. So to get by him requires incredible precision and timing and pretty much perfection on my part.
Ferrari is different. I believe we are also about the same pace, but Ferrari is usually in the NSX and has better cornering speeds but less straightaway speed and he's more willing to pass in the corners because he has to and usually has better pace there. He's a completely different challenge for me. He forces me to be a better driver because I know I'm going to have to run beside him for a couple of corners here or there to hold off his challenge. Sometimes I do, sometimes I don't.
Track, Cote, Sag, Orido, even Izzy, all present a different challenge and that's what keeps me coming back. Plus the fact that I can't seem to finish any higher than third place anymore...lol..
I thought for sure you'd come back and say it was too tight...lol. I'm glad you liked it. One general rule of thumb is that only in vary rare circumstances do any street cars benefit from rear wings. I have no wings on any of my street cars, unless they come with front downforce like an Audi R8 for example and even then it's usually minimum settings. Rear wings usually lead to understeer and loss of straightline speed. Grip can be tuned in to either end of the car without the wing.
, my Insight could consistently do 1:02.2.xxx, if I use it for Monday night, it will lose for sure 
Hopefully it works with all cars and not just some or it could play havoc in longer races
