Mando I am certainly a learner on this but the Corner Weighting link (p. 1) above is a very good one and makes the point, " If you don't want to change your ride height then a more balanced approach would be appropriate such as making small adjustments to all 4 wheels--add preload to LF and RR (extend coil over), remove preload to RF and LR (shorten the coil over)". (Note, the examples given are for a left hand drive car)
I also think that although your ride heights may be equal when you are not in the car they are almost certainly not equal when you are in the car. Thus the suggestion of using a few 20kg weights in the drivers seat is a good one as you can measure ride height and corner weight while out of the car. |
How good is this !!
This has just got to help a whole bunch of us. Good job everyone |
Would need a few 20kg weights to balance me out :)

U can sit in the car with the module as well. Key thing is get the static no driver weights equal and then with driver in achieve 50% on the crossovers.

Here is my last reading with No Driver (tools added and RF still to be adjusted a bit):

Merv ... sounds like you`re having too much fun playing with the scales !! I found the same thing on turn in and overall handling . My ride heights w/o driver are slightly different than with driver , but the guy that set my cross weights only does it with the driver`s weight in the car .... also sets the toe in/out , camber and caster with the weight in the car .
Like you , I`m still learning ... and found a good article on Longacre`s site about squaring a car . The point they make is that you want the rear suspension to be exactly square to the front suspension , not some point on the chassis . Took me a ling time , but I got within 1/64 " ... can`t wait for another track weekend , but winter is coming on now . Bob PS ... just got a new Mac and haven`t figured out how to attach a link yet , sorry . |
You lost me there Motobag

spammer, has now been reported to mods.

thanks for cleaning up the spam mods, back to the scales, Bob how did you square it all up to such a degree of accuracy?
|
I think this was the article Bob was referring to
Longacre Racing Online -- Tech Article "Squaring a Race Car" |
The assembly line was in progress yesterday. Now the scales are off to the Gold Coast and Brisbane members! Thanks Warren!
