There's no binding anywhere in the suspension, and moving the shocks makes no difference. The car does seem to need a little more on-power steering, so I'm wondering if this characteristic was engineered into the car...

It's more a function of leverage than anything. The rear shock mounts are mounted further away from the hingepin than the front mounts. That position gives more leverage to the shock and shock action. You will notice that on any car that has differing shock mounting positions.

Hi SMcpot,
That lacks on-throttle steering is really classic for this kind of car geometry. Mid-Ship with motor below the middle shaft, just like 414M.
Change to bigger caster angle and use front kick-up should help.

another fk question
okay i just put together my fk yesterday and i noticed when i put the shocks on they were the same because they were whites all around. So i found a Purple Xray shock in my box and put it in the front.
I believe for racing it is supposed to be hard in front and softer in rear. So purple is softer than white right. But when i compress them with my hand on the car they feel the same. Is that wrong? I even put the clicks in the front on hard and softest clicks in the back. They were still pretty close. Could it be from the shock oil? I only have 30w. If so what weight should i put in the front?
And for stock racing on carpet whats the best shock setup?
thanks
Jon

purple(33lbs) is way hard and white(17.5lbs) is way soft. they should be within 5lbs of each other.
as far as carpet setup, i would look to josh. goto cefx and download his nat's setup

i don't know. Never had that much difference between front and rear shocks. With my setup, they are pretty even. and with carpet the rear has very little travel, would be hard to tell that the front is stiffer or the rear or they are the same.

oh okay, so i am not crazy at least that is correct. I guess i will leave it as purple front and white rear until i get some more springs. I was going to put tc3 ft shocks on it but i couldnt figure a good way to put them on it.
Anyone know a good set up for stock carpet racing?

Yup-Josh's Nats set-up is a great place to start. Thats where I started and cars been great ever since. I change things a tiny bit every run-but nothing major-just to learn what a few shims here feels like-or more toe-out here feels like. Josh's set-up is fast on corner speed and easy to drive.

To compare spring stiffness. Put them on top of each other and compress them until one is compressed totally. That one will be the softer one.

For me, I play around with a few sets of springs until I get a car which handles the way I like it - but generally the rear is softer by about one or two spring hardnesses.
