Geo, body on or off?

[berni29]

Hi Guys

I have my plus 2 body suspended above a fully (just about) built up Spyder Zetec chassis. It has the usual adjustable spring perches, but also adjustable rear A frames and the front arms are fully adjustable.

At some point I will need to do a full geo on the car.

I was thinking that it might be best to do this with the body off the car as it will be much easier for measurements and access. My plan would be to disconnect the springs, level the chassis up, get the lower F&R suspension arms horizontal and go from there.

Or am I missing something and I should have the body on? One possible risk is that when the body is on I may want the suspension arms something other than horizontal.

Does anyone have an ideal road set up for toe front and rear and also camber?

Thoughts please?

Many thanks

Weighted, as to how you intend to operate the lady
150lbin drivers side, 50 in rear passenger?

Suspect it does need sprung & unsprung?

Hi There

My thinking is that if the suspension arms are parallel with the body off then it does not matter because when body, lady petrol and driver are on/in I will just adjust the perches till the arms are parallel again while corner weighing.

While the body is off, worth having a chat with Spyder and checking the steering rack packer dimensions. The rack height affects bump steer and they use a simple device to check and work out whether any rack packers are needed and if so how thick.

If nothing has changed since the car was last together, then this is just a double check but it is much easier with the body off.
