Until I get a chance to put a page up or decide what we are going to do with the CAT I’ll pin this post to the top and add some stuff to it for awhile – there is also a link to the Petitrc site and the CAT page in the links on the right of our home page – check out the build review before you start. In addition the Oople site would be worth a look as well.
This seems to be most important

I had put this post on Oople, just thought it should be here too.
Firstly I would recommend looking at the set up sheets in the back of the manual before building the car. Unfortunately the manual was designed well before a lot of the development work was done so does not necessarily reflect how the guys have run it.
Secondly and quite importantly there are some features/settings on the car that can run you into trouble with the diff outputs both front and rear.
It is possible if the car is run with a combination of some of the following it is possible to snap the diff outputs if they drop into the output slot under full bump; (as shown in the picture below)
-Very narrow (Small amount of washers against transmission)
-Very laydown shock
-Short upper camber link
-Very short shocks
To check, hold the suspension at full bump with shock attached and make sure the driveshaft rotates smoothly and clears the slot.

I for one will be running an O ring above the spring retainer for a bit of extra impact absorption.

OOPS – how did that pesky Datsun 1600 slip in there ?
