Things that worked:
Guard TBD diff - super smooth, no noises, just works!
Sachs clutch and light flywheel - still smooth and solid after over 150 pro solo launches
WEVO trans mounts - now zero axle hop
Softronics flash - perfect driveability, no codes thrown, just works.
Things that could have worked better:
Fabspeed race exhaust and long tube headers - great performance, light weight, but 105 db sound levels. We ended up with supertrapp plates added to the outlets to tame it down. I have built a 2nd system with larger diameter magnaflow mufflers, but it is still too loud at high revs.
AOS (oil separator) failed when I tried out running the stock throttle body/plenum. The stock TB uses 2 vacuum ports to the AOS, where the IPD plenum uses just one. After one event with the stock TB/plenum the AOS started letting oil by and giving us smoky startups.
Power steering overflow line - for some reason ours was routed to the valley on top of the engine, causing the excess fluid to puddle there. Not great as it has been known to catch fire. It has been rerouted to below the engine bay now.
Assorted Cone mangled body trim
Duck tail rear spoiler - it looked nice, but not sure we could feel the difference...... 3M trim tape will allow you to build a no-drill spoiler though.
