2K setup

[mpg200]

I have a cat 2000 that i race at york, now i have replaced the oneway layshaft pulley with a fixed one to give locked up 4wd. But the think understeers like a shopping trolley on the polished spoorts hall floor and then snaps to oversteer as soon as i apply power, Is this because of the fixed pulley or is it because my set up is just cack?:blush:

Can't help on the setup I'm afraid, but where did you get the one way pulley and things from ?

Interested as I'm rebuilding a Cat 2000 at the moment and the parts I have don't seem to correspond to the manual ! :o

Hi

i drove that car ( 2000 & EC whenit was new...

use the old grey schuey springs front and rear ( EC ) or the yellow ones ( 2000 )
Shocks:
-back; 4 holes 40wt
-front; 3 holes 40wt
camber links should have the same length f & r, on the inside they should be somwhere in a middle hole, same height f & r
under the front camber links on the outside,you but an M3 Nut under the link to raise it, you will need an other cup there ( Kyosho ones work good)
on the wishbones, use the outer hole, on top, the front shocks should be more laydown then the rear ones

It will understeer on polished floor with the fixed front diff, as there's no diff action. i'd just run a normal diff or something, then you could mess around with it, tightening it up of loosening it off to get the right feel.
