K2 setup help needed

[hardijs]

hey guys!
just drove my K2 for the first time at practice before upcoming race next week, car was easy to drive only problem was with smal edgy ramps.
So asking to you all for advice how to improve cars jumping on small edgy jumping boards.
track is onroad carpet, but for buggies on track are placed jumping boards...so my K2 struggle to handle those, as they are edgy and hit my cars end badly... so when I wish to go on those ramps on a throtle (as xrays and losis do with no problem) then my car is upside down...
My shock setup is 3-hole pistons- white in the front shocks and black at rear, oils front 550sct and rear 450sct.
As there is no parctice time before the race, so advice is needed from what to start to resolve this problem at race day.
I think that pistons change should help...but needed those which has more damping, so will those be 2hole pistons or 4hole??
Or its betterto start with oil change to more heavy ones??

What ride height are you runing and what springs

What ride height are you runing and what springs
I put black Core springs front and rear, as everybody at this track run hardest spring option aviliable (but no other schumi cars here), ride height I changed several times (in ranege form 16 to 20mm at front and 17 to 22m at rear) to try the best one I ended with ride height 18front and 20mm rear.
I personaly think that shock package is difefrent necessary....losis and xrays us 2 hole pistons- how about schumi cars, is it 2hole pistons used or not?

Personally I run on medium grip carpet and my basic shock setup is pistons
Front 500 oil blue spring
Rear 400 oil red spring
Also front diff 12.000 rear 10.000
Ride height 17mm all round

which pistons you use?
how many holes and holes diameter?

Kit pistons white front Black rear not done anything with the holes if the track is very bumpy I would drill the holes out front 1.6 rear 1.7

Here's video of track, it changes each time, but ramps stay the same, just in different positions.

I'm driving 22-4 2.0 and I also wouldn't say, that those edgy jumps are handled very good by my TLR.

and when I added stiffer springs and oils, than car loosed some of the handling characteristics.

Hi, I am running small bore shocks with 2x1.2 front pistons, 600cst oil and 2x1.3 rear pistons with 450cst oil, green springs all round. I also run the 2mm chassis and 2.5mm rear top decks for a bit more flex and don't run the chassis stiffeners at the front. The car was awesome I'm just going to try the 7.5 degree front castor blocks for a touch more initial steering.

Kit pistons white front Black rear not done anything with the holes if the track is very bumpy I would drill the holes out front 1.6 rear 1.7

so our oil setups was pretty similar, but I with even a bit heavier oils felt that more pack is necessary.
but, ok now I have some ideas to try out.
Thanks to all for help!

Are you running a shorty battery pack / configuration?
Have you tried moving the weight balance around?
