This set up works perfect for my weight distribution, tires, wheels, wing, etc. No push and not loose, puts the power down well. The engine is back about 7 inches. Without the big rear wing you could run a softer spring and retain the rear bar. I had to run that spring as the wheel wells would push into the tires down a fast straight from the downforce.
With a turbo car measure off corner over steer when the boost is not coming in too hard.
Always remember when fine tuning your set up, the shocks do more into and out of the corner, and springs /bars the middle of the corner.
