Mid Season Suspension Modifications

This year working with the Nissan Pirelli World Challenge series I learned an immense amount about professional road racing and vehicle setup. There was a ton to learn but I did my best to absorb everything I could from the talented and experienced people around me and my goodness I had no idea how involved professional racing really is. Since then I have made it my personal mission to learn as much as humanly possible about vehicle and race dynamics to not only apply to the #07 Nissan 370Z but also to my own #44 G35. With the chassis being very similar between the two models I was hoping that I could apply nearly the same setup knowledge I learned from the success at the end of the year with the #07 370Z and get the #44 G35 to handle equally as good for my time attack purposes.

Along with this new knowledge came some new SPL Suspension Parts to help me achieve my goals including rear adjustable mid-links (spring perches), traction arms, eccentric lockouts and some stiffer Swift Springs for the rear. My plan was relatively simple; go way more aggressive on everything, everywhere. More spring rate, more camber, more toe (out front, in rear of course), more rake, lowered ride height (just enough so the splitter doesn't rip off), stiffer sway bars thanks to Hotchkis and while I was at it more aero!

Now i'm sure at this point anyone who cares enough to be reading this is hoping I tell them exactly what I did on the setup... but for sake of keeping our World Challenge setup and my Global Time Attack setup to ourselves for competitive reasons I will not be posting my final alignment numbers. But I will say that thanks to the SPL Suspension Parts I was able to implement the exact setup I wanted which would not have been possible within the adjustments allowed on the factory components and was even able to correctly corner balance the car for the first time at a final 50.00% cross weight easier than ever before. I will be testing the new setup in a few weeks at the Z Nationals track day at Atlanta Motorsports Park and hopefully playing with the settings on the KW Suspension Club Sports to further dial in the car and see how the new setup affects the handling. Check back soon for the follow up.
