Aero and Suspension Tuning With True Type Coilovers

The fix will allow me then to do aero tuning that I need to maximize front and rear aero.

So my initial question to Danial at Awesome Performance Racing was did he think adding front splitter diffusers would be beneficial with my current setup and the whp I will be running in the future? He initially said no and then after I sent him information on my coilovers, he provide the information I posted and he asked me for some data so he could figure out the best spring rates for my Z. He specifically asked for corner spring weights and for me to give him the spring lengths front and rear when the car is unloaded and then compressed as this all matters when considering spring weight and drupe. The other thing to consider is that if your wheel rates are off you can over work your rear diff. This maybe one of the reasons some have issues with overheating their rear diff at the track or on canyon roads.

I figure if he wants to help me fine tune my car setup I am going to listen and take in all the information I can. His credentials and the people race team he works with speaks volumes. Oh and he said the diffusers would be beneficial.
