Nicest part of hell
So I bought a SRT Viper 13', tuned the hell out of it and expected mediocre American Muscle Car handling. I was as much blown away by its handling as my competition when I raced it in a 650 max PP race (Power restriction set to 622PP), it eats McLaren F1's for breakfast, with racing hards.

I'm not complaining here but why does this thing handle as good as race cars that have 500/700 down force?

I added a wing, a flat underfloor and a body mod kit. According to the car settings sheet the rear downforce maxes at mere 15 and I have zero front downforce, yet this thing handles like its glued onto the track.
I can do 2:02's at Mount Panorama easily with racing hards and power restriction set to 622PP which beats the times I set with my 630PP Mazda RX7 touring car and my 638PP Corvette C7 race car by 2-3 seconds and is only 5 seconds slower than my best run with my Bentley Speed 8.
And they all are purpose built race cars with tons of down force.
 
For realism I would take off the spoiler and flat floors, and use sport soft tires. Then compare it to a race car.
 
I'd be curious to see top speed comparisons for the cars mentioned versus the Viper. Bathurst has some decent straights and if you can keep the nose planted the Viper should have an advantage there. Also, what were the horsepower and torque figures when limited to 622PP?

Because the only way to compare a road car tuned to race to a race car is to handicap it? The subject is the car's prowess as a race car, so why not equip it as a race car as much as possible?

Yes, but Bathurst also has a set of high speed corners over crests where downforce comes in really handy. With the current setting the cars used for lap time comparisons (RX7 touring car, C7 GT2) pretty much have the same top speed on the straights, about 280 on the mountain straight and 305-312 at Conrad straight, no advantages here.
I'd have to turn on my PS to check its power figures but I think the C7 is around 470, the RX7 around 465 and the Viper ~ 500. But its also heavier.

I was implying that the add on parts to make it more of a race car are not really realistic. You say its a handicap to take them off, I say its way better than it should be with them on. The viper would be a ton faster without the flat floors, but quite hard to handle at that power.
 
Does the flat floor actually do something? In reality it should add some down force and/or decrease drag but people say it does nothing in GT6 and it did not increase downforce according to the car data sheet.

My question is why the car - a tuned street car- can easily compete with purpose built race cars even though it seems to have almost no downforce and there is no unfair power advantage.

I've noticed increased weight hsving an unusual benefit to the cornering ability on some cars. I don't know if it's an issue of surface shear not being represented or if it decreases contact patch deformation or whatever other possibl reason. It also strikes me as odd that understeer isn't ncreased substantially whe everything I've read on here points to flat floors only affecting the rear. It's a bit beyond my comfort zone but I'm intriued enough to give the car a try.

It adds a massive amount of downforce. It probably doesn't show up because it's not front/rear type of downforce is sort of the whole car...and not adjustable.

I've experienced increased straight line and corner exit stability with the flat floors while turn-in and continuous cornering suffer. I also pay little attention to the actual downforce number (unless someone can show me that it isn't an arbitrary figure) because the built-in and add-on downforce figures are so wildly different.

Aha, that makes sense and also explains the mysterious drag - the car tops at around 310 kmh even though its has no front and very little rear down force. With 500 kw, no wing drag and the current weight it should easily do 340 if not 350.
 
Who's to say how well the '13 viper handles Ive never driven one in real life & they have put a lot of work into its handling since the orgional model. Just look at all the aero crap you can buy for it, the thing looks & drives like a GT3 monster. It just sticks to the road. I wish they would make a DLC model just like my avatar. Im sick of vettes.
 
Love the '13 Viper.. 1000bhp+ with aero upgrades and it still handles very well :) Similar to the ACR Viper from GT5 (which I haven't tried in GT6). The Aston One-77 is a similarly well handling car with 1000bhp+. I usually don't tune the power on cars so far, but the Viper and one-77 respond very well.
 
Remove the flat floor and see how much PP went down, then add power, reduce weight to reach same PP, it will be faster than with flat floor in terms of lap time.
 
No offense, but you should be a bit quicker in a racing car than that. For reference (and I'm an exceedingly average driver) I can get an Audi R8 GT3 around Mt Panorama in 2:03, so a Bentley Speed 8 should be closer to a 1:51 or thereabouts. But yeah, horsepower makes a big difference at Mt Panorama, especially on the haul up Mountain Straight.
 
The only way you could argue that a heavier car handles better is if your talking in terms of ride quality. You won't feel bumps as much. Corner speed. No.
 
The new SRT GTS has a good amount of high speed grip that's intensified greatly with the body add-ons.

Fiat owns SRT, so it has some italian stuff in there. That's why it can now corner.....

For what the 2nd-4th gen Vipers competed with, they weren't too shabby for the most part when it came to performance.
 
Viper ACR being fast shouldnt come as a surprise:
http://www.autoblog.com/2011/09/15/dodge-viper-lays-claim-to-nurburgring-record-with-7-12-run/

Then again ACR to viper is like a Nismo GT-R or TRD for LFA - a "factory tuner".

I loved the car in GT5 - got it decently tuned after a while of fine tuning and was beating some serious machines online at 600-650pp. just too bad it doesnt have proper front aero in GT5. Still havent tried it in GT6 but i will for sure..

The ACR is beast mode. It has (non adjustable) aero in GT6. 100 front, 200 rear.

I recently did an Arcade Mode time trial shootout with all the Vipers, oil change and sports exhaust as the only mods on each. SH and then SS tires. Even with all the extra downforce, the ACR is still only about a second faster than the '13 GTS at Trial Mountain Reverse.

IMO, the Viper's main advantage is the bottomless pit of torque coming from that low-revving V10.
