I just bought the Avid top shaft and Triad slipper setup. It is far superior to all the stock slippers and is also lighter too!

RB5 WC combo from speedtechrc.com ($45.99) is a good deal for standard top shaft and you could still use AE spur and pads.

For anyone who uses the exotek steering parts, does it eliminate much play?

I'm considering the WC set, but not sure.

Also planning on running standard bore shocks

Avid top shaft $20-$30 allows you to use the AE gear as well or the Avid slipper.

I'd like to know further: For anyone who uses the exotek steering parts and have previously broken the steering plate, have they broken anything else yet? Like ripped the ballstud out of the steering hubs?

I haven't ripped anything from the steering though the front camber link mount is another story. Had to move the stud one in since the outermost got ripped out by a whack. I ordered the exotek parts now.

Default Avid clutch system

for those using the Avid slipper system and gears . before you install the gears on it make sure you soak your spur gears in a sealed zip loc bag for at least 48 hours to put moisture in the plastic other wise they will become noisy. they are molded in a zero moisture atmosphere. my car was getting loud now it's nice and quite.
