Corner weighting
Discussion
I've read in several books that corner weighting should look to equalise the diagonal weights on the car to make turn into both right handers and left handers the same. However, the last two corner weight setups I've had (on a caterham), have both sought to balance the weights over the front axle - presumably to prevent lock up of one particualr wheel under hard braking. When I've looked at the print out from the scales, the diagonals are some way off.
Anyone shed any light on what they think is the correct 'target' , i.e. front axle balance or diagonals being equal (this is the way the NASCARs, etc are setup, with 'wedge' or without).
Rather than pay £150 upwards for someone to wind up the spring platforms, I know my target ride heights and have access to a set of CW scales, so will do the job myself (with an assistant obviuously, as I'll be in the car!).

Depending on what youre trying to set-up (front/mid/rear engine) decides weight distribution. The 50/50 front rear is often difficult to obtain due to where engine/box are.
The idea is to balance the weights across the front,after setting the ride height correctly both sides, adusting the rear pushrods/spring height to bring the fronts in. The rears are not as important as the fronts though if they are wildly different there may be something damaged somewhere.
The 0540 Lola had on the front fixed lenght pushrods that only adjusted height, you changed a shim to lower or raise the nose then adjusted the rear pushrod lengths for cornerweighting.
Basics often missed - tyre pressures, disconnect roll bars, half - 3/4 fuel load, driver ballast.
