The Deamon Theives catalogue (Deamon Tweaks) list some stuff for a probe. They even list a lowering kit for a 6.
Parts available from Memory:
FSE Boost Valve (Listed for the probe but it fits)
Eibarch Springs (listed for the 6)
Scorpion Back Box (Listed for the Probe but fits)
Short Shifter (listed for Both I think BUT according to dave didnt fit!!!)
Cant think of anything else they do except universal stuff.
