The effect of the stock slipper is a big kick of forward torque .. a bit like a 3 gear I suppose .. taking some of the weight out reduces that effect.

If you want to try it for yourself, take out the tranny with motor and all still attached, and fire it up while holding it in your hand .. it's quite surprising .. you can then take bits off and directly feel what effect it has .. thats what I did ... my final choice of a fully stripped down slipper was because that was the most neutral of all the options .. :thumbsup:

So is it counteracting the torque effect of the motor, which in mid motor layout should be helping with rear traction? Or is it giving a big shove of forward torque, which would not be helping me with the wheelspin issue?

Its more than countering the effect of the motor, which won't help if you're suffering wheelspin and low rear traction ...

That is very useful info, I will give it a try. Thanks Speedy :thumbsup:

So realistically, to race on dirt I'd need to take the slipper down to minimum plates? I'm already running MM, Ive managed to mount my Tekin RSX to the rear of the chassis (between side gears and dirt guard- it's not pretty wiring, but the weight distribution seems sound).
I'm hoping it'll work...
