It will be a semi stripped down car with 930 powertrain and RSR fuel tank. Looks like I have two options for rear coilover shocks, and two options for front inserts (HD & B8. I already have the coilover struts). The car will be running 15" RSR wheels with spacers (If needed).
So what would be a good guess on my spring rates and shock options?

The thing to know to compare t-bars to coils is the motion ratio that gives the actual wheel rate
this is a slippery piece of information because it isn't a constant so you have to use an average
for a 911 w/ stock suspension arms
front motion ratio on average is 0.894
rear motion ration on average is 1.018
wheel rate =motion ratio^2 * spring rate
spring can be either t-bar or coil
