Fastest Laps in Production Cars

[Disturbed07]

I was wondering if anybody's interested in posting times for various production cars on the Nurburgring? I see lots of times with super-fast race cars, but not so many with cars like Vipers, BMW's, 350Z's, and Corvette's, and the likes of all these. I'd really like to see how my times with these cars stack up, as I have a regular controller, my thumb's good, but no better than about 5 minute-flat times with F1's and such.
I'm mainly looking for Viper times, because it's such a difficult car to get just right, and I wanna see how I've done with that.
Any thought's? any already known good times in some cars?
I've got these, though I don't have the tenths and such, as I'm 1000's of miles from my PS2

Yes, I forgot to mention, all cars I have are with stock equipped S2's, those are the only times I have

Dodge Viper SRT-10: 7:11
Nissan 350Z: 7:39
Chevrolet Corvette ZO6: 7:21
Aston Martin DB7: 7:36
BMW M3: 7:39

What tyres? If you're going to do laps in standard cars you should do them on authentic road tyres (N2s or N3s)...

I have a very detailed opinion on that, but to keep it simple, I realize that cars in GT4 perform more like real with N tires, I also believe that the tires, for instance, on a Viper in real life not only are huge, and you can't really upgrade in size without extensive modification, but are also some of the best tires money can buy, therefore being at least S2's by definition, likely S3's, as they are sports tires, and they are soft sports tires, so it's kinda weird taking that away, but regardless, I am unable to record times with N tires right now

I seem to be asking for proof a lot lately and this is no different. Proof of what you're saying would be welcome...

Most people agree that the S tyres in GT4 (especially the S2s and S3s) are modelled on real-world semi-slick high performance dry weather tyres (think Advan A048). The Viper comes with Michelin Pilot Sports standard, which are all weather tyres with run flat capability. They are high performance tyres, no doubt about that, but they're not semi-slicks.

The size of the tyes is irrelevant as this will be a taken into consideration in the game (i.e. a Viper and an S2000 will have different size tyres, no matter the compound).

Scaff has done an interesting tyre analysis, take a look.

The tyre type that most closely matches that of the real world test data are the N2 tyres, with a Lateral g range of 0.99 & 1.1.

The S2 tyres take the level of grip in the realm of track-only tyres

well, my definition of "sports" was high. and ultra high-performance street tires, being so many levels of street tires, there "should" be a much lower level in that case, like, the tires you can get starting at 25 dollars per tire....
It's a very good point to say they may be drag radials or some other kind of basically-bald tires like that, and I've wondered myself about that many of times, however, for the life of me, I can't understand why they'd have all cars come with them stock, and also why they would call them sports tires, instead of the old "semi-racing" which is a far more fitting title.
Plus, the pictures they show are normal, street 10/32nd depth Yokohama's if I remember right, either way, they don't look like shaved tires of any kind
