I don't want short travel, I want long travel up front. Short springs also means stiffer rates. Also, with the stock camber plates I ran out of adjustment because I had to lower it so much the springs actually lost compression at full droop, and pre-loading the springs more meant the car got REALLY high (stock ride height) to get it at acceptable pre-load.
Anyway, My basic suspension philosophy for this car right now is this:
Stiff front swaybar, Softer/taller front springs...
Soft rear swaybar, Stiffer/shorter rear springs...
More quality dampening (shocks) less reliance on stiff springs (IE over-sprung)
The rear suspension isn't capable of a lot of travel, unlike the fronts (Pretty common information bout the design of the Subaru rear subframe they use in this car plus the Imprezas/Foresters) and with the rear suspension unless you are running an expensive clutch pack rear diff, needs as much independence as possible to keep the wheels on the ground (as I learned running the stiffer rear bar).
Some more background information... I used to have a '95 Impreza that was fully built suspension wise with EVERY single bushing in that car being replaced/upgraded (a couple of them took trial and error to reduce NVH) granted I had crummy coilovers for awhile that were over-sprung (Megan Racing, I had one of the first sets for the GC's) that car also had a front Helical diff and a rear viscous which made it VERY grippy and weighed about the same as the twins since I was running it N/A (EJ25 running about 180hp with mods).
With that car, it was all about swaybars being almost even front/back and spring rates being almost even front/back. But that car had a Macpherson rear as well as front so it had a lot more travel in the rear than the BRZ does but wasn't multilink and had static camber. That car was OK to lift a rear tire because it didn't cause snap oversteer with the diffs I was running and I actually run rather mild swaybars for that car and focused more on using suspension settings to adjust the cars handling balance, but I did have to go through a couple swaybars to get that car right too.
