Cat 2000 Setup help

[Conrad]

I'm after a little help in setting up an original (upright shocks) Cat 2000. First time racing the car competetively indoors today for about ten years and a few old memorys came flooding back, namely its crap over rumble strips compared to the EC that replaced it or other buggys.

Setup is straight out of the box, 30wt oil front and rear, grey springs (AE shocks), dunno what piston. Long wheelbase, cells to the rear, one way layshaft, standard top link and shock mounting positions and -1.5' camber all round. Racing indoors on carpet with mini spikes, there was some understeer entering the corner off throttle but the main issue the car being badly unsettled over the rumbles.
