You want to preload the coils enough that they don't fall off the upper perches when the suspension unloads under normal use, or use a tender spring to pre-tension them. You hit the idea, to set the ride height a little low in the rear with the T-bars, and bring it up just a bit on the coils.

For serious track use, you can't get enough wheel rate from T-bars alone, "helper" coil overs are a must, and don't really produce the balance issues you would anticipate. A complete coil-over setup is ideal for mostly track use to outright race cars, to get enough total wheel rate to control weight transfer with big sticky tires and such, but a complete cage tied to the pick up points is mandatory.

The 934 used T-bars and coils because of rules constraints...
