Really, people just throw all this power into the car and expect it to fly. In a straight sure it will, but around turns you got all this extra power, what do you think will happen? I leave the cars stock mostly and just lessen the weight before adding all this power. Race tires help a great deal too. Forget the softs, add mediums and go from there. Do things in increments so that you can tell what the difference is. Don't switch so many things at once. Do one thing at a time before you test drive the car again. Then you understand what happens.

This is true, not to brag but honest the only ACR I have ever seen be able to go through corners is my own, everyone else's is terrible. The only time I have trouble is when I put to much power down, but if you know how to control your own car it is no problem.

I went up in increments too, I first wanted to see how it would do in the Tuned Car Championships and all i had was an oil change + $500 intake + stage 1 weight, did pretty good if i kept trying im positive i would've gotten 1st. ended up finishing 4th because i kept getting pissed off on the last lap, my sports tires weren't giving me enough grip while it seemed all of the tuned cars had race tires.
i went back and bought twin clutch and semi fly wheel and finally put in medium race tires. the car flies, my closest competition was at least 5+ seconds back and it was a s2000 gt1 turbo. with sloppy i just want to get this over with driving!
my numbers are:
661hp
601tq
1396kg
Mods: Racing Intake, Sports Cat, Twin Clutch, Semi Flywheel, Stage 1 weight and medium racing tires.
I tried to actually copy the viper acr-x, but went a little too far with losing weight and adding hp.
jjohan35,
thanks for the settings, ill try them out when i get a full susension set up. and dont listen to people that dont even have the car in the game from their perspective they are just bench racing
. It may not be close to real life, but PD already f'd that up when they didnt supplement an adjustable ACR front splitter/dive planes and adjustable rear wing.

The problem is that with each 'increment' that you suggest, it completely changes the tune. And honestly a lot of us do not want to re-tune the vehicle after each incremental upgrade. And I disagree with getting racing mediums. You're suggesting to people to get tires with less grip for a car that has trouble with gripping the road as it is. You also have to understand that we are adding power not to increase in speed, but to increase in acceleration (or decrease acceleration time). We can always adjust our speed with careful throttle control, so it's pointless to discourage upgrading based on too much 'extra power'.
Not a problem. Thanks for giving my tuning a shot. I made a few minor adjustments to the numbers I posted earlier, but I don't recall them (gave the car to my friend). Once I get another Viper ACR, I'll post here any new findings.

It's all good. It's just a racing sim so nobody is dying. I just find it kind of funny that there are folks who would tell you how the car behaves without owning/driving the modded or the stock version of the car. Credibility at that point just goes down the drain. According to Vipermatt, in real life the Viper has stiffer springs in the rear as well, so it has nothing to do with real life versus in game differences. Most people on this site are friendly and helpful though.
Not to my knowledge, no. It absolutely sucks. I'm getting sick of trying to remember which setup I used for which lap times. It would be nice if they recorded the setup with each lap time within practice mode. And I also wish practice mode lap times would be posted online/public so we can try to beat our friends' lap times on the same track given the same horsepower limit.
Regardless that's one of the reasons why I'm sharing my setups for my various cars on this forum. It's one way to record my progress with the tunings without having to write anything down somewhere. GT5 NEEDS the ability to save multiple tunings!
I finally got the car back. My friend and I both tuned it and we found a tuning that we both liked. Let me know what you guys think.
Top Speed 261
LSD 8/20/30 (I brake before corner entry, not after corner entry, and I drive over rumble strips at chicanes so I need the braking stability, please turn this down if you are having problems with understeering with your driving style)
Ride height -14/-12
Spring Rate 12.5/16.0
Dampers Ext 5/6
Dampers Comp 5/6
Anti-Roll 2/2 (I'm a firm believer of stiff springs with soft anti-roll in this game and in real life racing)
Camber 2.5/2.4
Toe -.10/.02
Brakes 6/5
All upgrades, mods, and tunings installed except aero kits. I'm running on soft racing tires.

ill be giving your tunes a try tonight jj...ive been messing with this car a bunch as its my favorite car...its fast how i have it i think, but i know there is a lot left...i think my biggest problem so far is not being aggressive enough in my tuning...im trying changes that are too small to notice much of a difference...
thanks johan

I think it's the best tune I've used so far. But it still understeers too much for my liking. This thing has GOBS of grip on the rear end (like it should) and it takes a ripping to make it come around. If there was just a way to get the rear end to come around a little more it would be perfect...
Bump up the anti-roll from 2/2 to 2/3. Stiffer rear settings promote oversteer and reduce understeer. I personally do not have a problem with the understeer but I'm using a racing wheel. And drop those LSD settings to your personal taste, maybe down to 8/20/10 if it suits your driving.

ill give it a shot tomorrow (done playing for the night)....i wouldn't say understeer is a "problem" with your tune, I would just like to get the rear around a wee bit more for my tastes...i think being able to adjust front downforce would help that...alas PD made a boo boo with this car...

Hey JJ, first off lemmy just thank you for your tunes on various vehicles. Your 2nd LP SV tune is pure gold, perfect for my driving style. I just owned GT all-stars with your tune on my SV, a feat I was unable to do with the ACR. Theres still too much understeer, I cant get my laptimes anywhere near my SV's times even with the 350hp difference.
Im using a wheel aswell (G27), however my driving style is more to throw the car into a turn with good speed then overcompensate aiming tighter then the turn exit. This requires some oversteer which the SV with your tune has, the ACR on the other hand does not...its all understeer understeer understeer into the wall.

No problem. Glad the SV tuning worked for you. 👍
I haven't provided a 2nd tuning for the Viper ACR yet. Not sure if you read my other post on the SV, but I wanted to provide at least two different tunings for each car I post up so that users like yourself will have options since nobody's driving style is the same. Unfortunately I will be out of town for the next few weeks for family obligations on my side and the wife's side. She lets me completely mod the Civic Si in our family, but still won't let me touch the Lexus IS at all! I'm hoping our 2 week 'vacation' will convince her otherwise. =T
Anyway the ACR is tough to tune. I've driven a real Viper (non-ACR) on the track and it definitely handles differently than most cars I've driven. I've tried every suggestion in this tuning forum without satisfaction. If I correct the understeer, the car will start to spin out really quickly. But if I leave the understeer, nobody is really happy. I'll be sure to try a completely different, radical approach than my first tuning for the ACR (as I did with the Murcielago SV) and hopefully it'll work. I'm starting to wonder if it's best to just ask real life Viper owners, but I don't know anyone who owns the SRT10 ACR version.

Both of you are answering the wrong question in the first place.
GT uses kg/mm as spring rates while lbs/in is common in the real world. The conversion is lbs/in divided by 56 for kg/mm and kg/mm multiplied by 56 for lbs/in.
