Need help tuning Dodge viper gts

[moetec]

Hey guys

I have a dodge viper I have worked and is making around 930hp, very powerful beast,

As i realised the tyres very **** house i have bought it the most expensive race tyres,

Now i have realised the cornering is gone down hill, how do i get the cornering to be more smooth and quicker response?

I have bought the most expensive custom suspension, transmission and driveline mods to customize to my needs but not sure where to start if these will help out?

Any tips?

Well I'd probably slap on some racing mediums rather than the softs (just personal preference). After that, since it's a heavy car I'd probably start off by setting the front spring rate to about 16-17, the rear to about 15-16. Lower the front a bit but keep the rear higher by about 3 clicks. Front compression should be one click lower than the rebound for better response, maybe in the 4-5 range. Make the rear a bit more responsive (same theory though, rebound one click higher than the compression), around the 6-8 mark. I always keep camber low, about 2-2.5 in the front and always no more than 1 in the rear. To help turn-in, dial in some negative toe in the front to your liking, but make sure there's nothing in the rear to keep those tires planted. After that, I'd keep the stabilizers low, with the rear about one click higher than the front, perhaps in the 3-4 range. For downforce, don't make the rear TOO much stronger than the front, keep it reasonable. As far as the LSD goes, I'd throw it into open (5-5-5) and start from there.

Just a general high powered FR guide, but let me know how that works out for you.

There's another active thread on the Viper. And stick to racing soft tires. You need them sticky. There's no reason to get anything inferior, especially on a powerful car like the Viper.

I disagree. Sure, you can use throttle to induce oversteer, but just lifting off the throttle into turns produces understeer of all things. Racing softs mean the front end just has too much grip for my racing style (I prefer sharp turn in and late breaking).

You can reduce front grip at corners with suspension settings (and improve straight line stability at the same time). There is absolutely no reason to use anything inferior to soft racing tires unless you are racing in rain, snow, or dirt or you are on a very long race that requires more durability on the tires. You are sacrificing speed, power, and stability for choosing tires with less grip when you can achieve what you want with a few suspension tweaks.

You would suggest raising the spring rate on the front even higher so that under breaking there's barely any weight transfer, AND so that the front grips less?

I'd rather keep suspension settings ideal for weight transfer and use the right tires.

Uh no. Use camber and toe settings. I'm not going to revive this thread anymore bc there's a lot of bad info in here.

thanks boys i will try some of those settings, and active thread around on here? i will have a search hopefuly i will find it,
