K2 is going to be better than the K1.
I have driven the car on high, mid, and low bite tracks. Hard packed, and loose dusty. I think the car better on all of them. Not to say you will or will not have to make setup changes for your track. I have been to five different tracks all had different dirt/clay. I was able to get the car to work good at every track. K2 jumps better, is more forgiving, is more tunable. I'm very happy with the K2.

I am 90% sure I am getting a K2, but felt like I had to ask..

Not to beat a dead horse, but I have the forward conversion chassis for my K1. Will it be similar to the K2?. I ask that since the steering is also converted to the K2 style with that conversion kit. (same answer as before? I wasnt sure if that made a bigger difference,etc .)

Hi guys,
Been going over the setup sheet again.
What is high pin? Yes or no. In the rear suspension.
Thanks.

I think, that this is that plastic spacer under the RR hanger, so you can run it with, or without it, but i'm not 100% sure!?
May someone can clarify that?

Good question
Not sure it needs to be there! The way I understand it is, unless you're running more than 0 degree's on squat will will always have pin high! That the only thing the illustration show's is that angle.

It`s because of this part:http://www.racing-cars.com/pp/New_Ca...KF2/U4734.html
This simple kit raises the inboard hinge pin height which raises the rear roll centre. This stiffens the car in roll which keeps the rear end of the car flatter through corners, and is recommended for high grip surfaces.

Aha. It's a different part.
Another one. I'm still getting familiar with these kits.
On Orlowski 's setup in the notes section it states 2mm bumpsteer washers. Normally for bumpsteer I've adjusted the outboard end of the steering linkage. Trish from Schumacher mentioned in an email that it's the inboard link. I suppose because the ballstud is downwards that does the same thing in a way. Can you guys confirm that bumpsteer changes are on the upside down link the manual has 2 X 1mm and 1 2mm washer. I assume that for 2mm bumpsteer I just remove the 2 X 1mm. Correct?
Thanks guys.

After picking up the core RC Spring kits, some Pistons I'm going to drill out. Going to try 1.7mm X 3 holes. Try AE 37.5wt green/blue spring at the front and 32.5wt red/green spring in the back. Ahh yes that's after I get my diff sorted. Thanks for the advice on that.
Oh yes, Ordered my cat k2 bling last night on racing-cars.com, exciting!
CF chassis, 7.5° yoke, some ti turnbuckles, 10° pivot and couldn't help myself. My familiarity with ball diffs led me to buy a couple.
I'll keep you guys posted of my testing, I'm outdoors on dirt/clay tracks in Australia that can get a bit bumpy.
I encourage everyone to share their experiences, that way we can all get our buggies smokin' quicker then doing it in isolation. Are you with me?

I am also new to Schumacher and was wondering the same things about "pin high or pin low" and Orlowski's 2mm bump steer. I now understand the first item, but not the bump steer. In the manual, for the steering, there are no spacers for the steering link where it mounts to the steering bell cranks, the 4mm worth of spacers mentioned above are for the camber link. So back to how is one to adjust for 2mm in bump steer? If one were to add it to the outer steering knuckle, like for typical buggies, you'd need an ultra long captive ball end, U4739, to be able to use a 2mm spacer. The kit ball end is too short. I'm not sure how to do this adjustment inboard.

I'm not sure about the spacers on the steering bell cranks being for bump steer but adding shims softens the steering around the centre or neutral.
