ive tried the durango pistons but find it too soft, i usually run 1.7 two hole 650wt front and Rear 1.5 3 hole 400 wt or there abouts, as for bump steer just move the carbon plate to the underside of the hub and dremel the wishone to give more lock if required

I did try the plate underneath but thought there was just as much bump steer? Where did you get those pistons?

I melted the standard pistons to seal the holes and re drilled them to suit

You may also need to adjust your tie rods as well. Hope that helps.

Yeap carbon plates are underneath now , but also put washers on top over the Ackerman plate to lower that too?

Yes, kit pistons. Maybe changing them + brass weight will calm it down?

I just p the spacers under the ball joint. Still now you will see the difference that little change will do to the feel of the car.

Are you talking of the brass back underneath chassis plate? What difference do you notice if using?

I'm running 5 hole pistons, but where are you running your front top wishbones high or low on the inserts?

I'm running top front wishbones low in the inserts, but I'm not too worried about front-end, I just feel that the rear end needs 'calming down' over ripples as it seems lively in a straight line. Thats why ive asked about under chassis rear weight. Or will altering the front end have some effect?

I turned the insert around so the pin is in the upper position it calmed it right down and made it a lot easier to drive a silly thing I forgot about but a big change to the car bud

Well did maritime yesterday and had a few issues with setting it up correctly, however even though i wasnt on the A final pace due to not finding a solution to that the car did perform faultlessly, took some heavy impacts easily with a scratch so quite impressed with how sturdy the car is. After doing the bump steer mod and giving kick up to the top front wishbone and adding the under chassis brass weight it did make a big difference. I would advise buying countersunk washers and putting on the front shock balls (screw goes into the counter side of the washer) to stop them popping off as that cost me whilst chasing for a possible top three poistion in the B when a back marker hit me.

Some pics including the last one with the popped off shock.
Link to the Utube video of my final below but apologies for not doing very well, bit slow and as it was my very first time out with this car I could only make the B final but once I work out a pukka set up I aim to change that. Got up to fourth and pulling in the third and second places only for my shock to pop off so was not easy to continue but did never the less to the finish so had to settle for eight. https://www.youtube.com/watch?v=XBw4...MywZ-qHidaMpsQ
