Ok, I have the best upgrades for it ( I think ) Racing tires soft, all 3 engines, all weight reductions, super turbo, the 2 drive trains, and the 10k exhaust, along with another one(I forget, sorry). I also have the fully customizable suspension kit. Here's the thing: my viper before I got the turbo kit and tires and other upgrades, was very responsive, and the driving was the best I had yet in this game, but I wanted more HP.....now it sucks at turning. I take a turn, and either my car is too stiff, or if I hit the slightest patch of grass, I spin out like crazy. I'm wondering if you guys have a suspension setup I could use? I have no idea how to configure it to make the turning and driving the way it was before, but do any of you guys have this car fully upgraded with a really good setup? Please help me! I love this car!
 
Well the problem with the viper is the lack of a front air dam first off. As much as I want to love my ACR, it just doesn't work on tracks with long turns or any bumps because they always turn into jumps instead.... No downforce.
This might help you a little... toe in the back wheels .30 and the front wheels out -.20. Also drop the front end 12MM...

Here this is easier for me... haha

Be sure to set rear wing to 35 downforce.
Like I said, it doesn't do well on tracks with drastic elevation changes because the front end doesn't want to come down...
Oh and I'm not a "tuner" by any means so you know haha. Figured I'ld help you out.

And that is completely Polyphony's fault because the car leaves the factory with adjustable front and rear downforce as well as adjustablebride height....shame on PD for that oversight...I have to spend extra credits to not even get the full factory functioning out of the car...

It's not just ride hight that's adjustable factory-stock, the shocks are individually adjustable for both compression and rebound - they're trick units with external reservoirs too. Of course as you've already mentioned, the front splitter and rear wing are also adjustable right out of the box too. This car means serious business, right from the factory.
 
As the poster above said that set up was way to bumpy, though good around the turns... It didn't really solve the jumping problem. So I have spent hours now tweaking my ACR on Laguna Seca since at the start there is a small hill that a bus could prolly jump. So I figure if I can keep it on the ground there I will stay on the ground anywhere. So my set up is as followed. It looks way too simple to be effective but anyone can drive this car as is.

My ACR is fully modded out at 1027HP/1257kg

Transmission: Maxed at 286
Suspension: Front Rear
-20 Ride Height Adjustment 40
18.0 Spring Rate 7.5
10 Dampers(Extension) 4
9 Dampers(Compression) 3
7 Anti-Roll Bars 1

Wheel Alignment: Front Rear
0.9 Camber Angle 0.3
-0.20 Toe Angle 0.30

Brakes: 6 Front/ 4 Back

Rear Downforce:40

LSD: 5/5/5. I suggest starting off with 5/20/10 untill you get a feel of the new settings then moving down to 5/5/5.

Car now handles like a dream. Cut 3 seconds off my initial Laguna Seca time.

There is still some bounce at certain areas if taken too fast but can be prevented. if you feel the car is still too bumpy Take your Rear Damper Extension down to 2, and your Rear Damper Compression down to 1. The car will never come off the road but understeers so you have to take turns way slower. The setup I posted seemed to be the best balance between cornering and keeping it to the ground.

Click to expand...

I'm sure driver skill has alot to do with lap times so my time won't really tell much but my original time with the stock settings was 1.33.015. Time after my settings was 1.23.030.
That is only after 6 runs so I'm sure more time can be knocked off, but that is how it stands now.
 
You really need to be doing a lot more than 6 laps if you want to compare times properly. More laps with the stock settings and more laps after tuning. When your driving is consistent the difference between stock and tuned should only be ~5 secs max especially in a short track like laguna seca. 10s difference just means your initial laps weren't done properly, unless by "stock settings" you mean no upgrades to the power/weight whatsoever.

I agree but at the same time when I say I done 6 laps I ment that as in 6 laps default and 6 laps with my final tune as I was satisfied then. I can't say how many laps I've done total tuning the car. Hours worth to say the least. I wasn't comparing lap times when I was tuning, I was only comparing the cars handling etc. He just wanted to know my lap times so I gave what I got. 1.23 Was more of a practice lap to get a feel for the car. 6 laps after I think(I would have to look) I was at 1.29. 6 laps on my settings put me at 1.33. I do agree tho to properly compare lap times more laps should be run but as I said I wasn't comparing lap times when tuning just handling. When I get a chance. I reset my settings to default and run more laps then back to my current settings and run more laps if anyone would like a more in depth approach. As I stand now though, I say use these settings, get on the track and thank me later. :)

I have to add too that before attempting tracks like Nurburgring Nord. I suggest setting both rear dampers down to 1. It is still and intense drive(which I like anyway) but once I do the AMG event and unlock this tack for practice I'll do some fine tuning for all you pansies that want a smooth ride the whole way :P
 
I should try that setting. I can manage 1:21's with the stock set-up, though I'm not consistent with that time. I think 1:22 and 1:23 are usually what I'm consistent with. Mine's pumping out 1031hp.
