Yes they are cold drawn bars. Thank you all for the suggestions.

I am having some issues with keeping a machined 12L14 shaft straight after machining. The shafe is about 3/8" and a flat of over half the diameter is machined out of a section of the shaft in order to create a spot for a plate to rest on. While not being the best idea to cut over half the mat'l...

as someone said. to help even out the loading, plus 99.99% of people would never use it. there are always mechanical or electrical means of bypassing this safety feature though. locked hubs or some vacuum bypass for mechanical, and then there are electrical means that are fairly simply to...

Oops is there a delete, lol. I believe I mistyped. What i was getting at is that yes the ball joint moves in side view slightly with respect to the LCA axis. but by and large SVSA is controlled by angles of the LCA and UCA axes to eachother, but passing through the ball joints. So I dont see...

SVSA to my knowledge is not controlled by ball joints.

can you post a picture of the current setup instead?

no, bump steer /= ackerman steering

please tell us what book that is. I might have it. also the camber change should be explained not as an angle change of the wishbone in plan, but the outward movement of the upright's balljoint, for clarity

Right I believe what Greg and I are alluding to is that a complete 3 view drawing is required to ascertain more about the design.

again, probably not anti-squat since the zonda's view in plan (top). quickly looking at it would say it is going to toe out on bump, so that the outside wheel in a turn gains toe out. also on launch added toe which could be used to increase traction due to a higher slip angle. many...

please do post your matlab gui, and other code.

Front lower 0\ /0 Front upper 0| |0 excuse me but this is a top view of what it seems the OP is referring to. the 0 is the tire while the lines are the axes of the control arms.

I was sure that anti geometries were solely side view kinematics. From RCVD "[the anti effect] It results purely from the angle or slope of the side view swing arm." pg. 617. Basically it is the reaction that the suspension links take on as a result of braking (and their angle w.r.t. the CG)...

anti-dive is a side view geometry, no?

after some searching I used eqn. 6 here: http://en.wikipedia.org/wiki/Orifice_plate used my known small bench data (mass flow rate,k, and pressure ratio) to coefficients (C*A*sqrt(2M/ZR)) in one variable "X" then I resolved using this "X" and a new pressure ratio to get a new mass flow rate...
