The biggest issue with this car is that the setups are so inconsistent from one driver to another. One fast guy could be using the base line setup while another fast guy may have hours of tuning on his car yet they both turn the same lap times. This stems from the horrid tires this car has on it. Which comes down to this, there is really no right or wrong setup as long as it works and feels comfortable to you. This will all change (I hope) when the NTM gets on this car as all the current setups might become completely useless.
Now this is my 3rd or 4th season with this car. Hell I cant remember. This is really the only car I drive currently. And to tell you the truth, I am still fighting and learned about the setup on this car. Again, for me it just comes from the crap tires on it. I could go into more detail on that subject but that is not what you are looking for.
So, I will give you some hints on this car as far as setup. What I will give you will not be the magic bullet and might not help you at all. But it should get you a good start. You can either call it crap, which in all accounts there is a good chance you might as again, the tires suck and the setup stuff I am going to give you might not work for your driving style.
First off, rebound is important and misunderstood in this car. The official Sach setup guide for this car is incorrect and inconsistent to how shocks really work. (yeah I dont get it either but there setup guide for this car was poorly writen and hard to comprehend. More on this if you like. PM me)
Front rebound should be in the negative and I would start around the -30 mark. Never go into the positive on the front as that is a sign you are doing something wrong driving the car or there is a setup issue somewhere else in the car.
Rear should be in the positive and again start at +30. Never go into the negative in the rear as its something you are doing wrong or a setup issue.
*Remember, rebound is the resistance of the shock expanding or becoming longer.
Front ARB should be Med and Rear ARB should be soft
Keep the ARB preload to 0 or as close as possible. after one change in the car the ARB preload will be off of 0. Reset it to 0 and continue tuning the car.
Toe- The rear should be either 1/16th or 2/16ths and the front stay at 0. No mater what others say the toe in the front stays at 0. That is a rule of thumb in alignment of RWD cars and is always that way unless the vehicle is a FWD.
Ride Height - Your on your own on this one, I cant give you all the answers. But as a tip, rake is good. Read up to understand.
Caster - Start off with it around 7 degrees and go from there. Read up on caster to understand how it works. Remember that caster settings create dynamic camber angles. The higher the caster degree the greater the camber dynamics
Camber - Figure this one out on your own. Every track is different
Tires - read Camber.
Shock Bump - Start the front out at 16 and go from there. The stiffer the rear the more stable the front will be but there are side effects to that. Read the setup guide linked above.
I hope this helps and if you have any questions I will be more then happy to help you. But I will not give you any setups.
Remember, setups are like finger prints, they are all different and all unique. I can try to help guide you to where you need to go
