TR6 springs and shocks

[Chad Stretz <ccfarm@tranquility.net>]

Hey Scions,

ISTR a thread on this about a year or so ago, but my computer crashed
since then, and I lost all the info.  So here goes:

1.  Which rear springs (Moss, TRF, BPNW, etc.) will give me a stiffer
rate without changing the ride height?

2.  I know that Apple Hydraulics sells uprated rear shocks, but can I
buy just the valves and rebuild mine myself?  Anyone tried this?

TIA,
