Nice very useful to have posted up here.

It should be noted that comparing these values to ones provided by other manufacturers rates for ARBs should not be considered exact. The anti-rollbar rates were just calculated not directly measured, so the delta should be accurate between each model year, it may not be accurate when comparing the rates to an aftermarket bar like Eibach, ASM, etc. Best to look at the data that each manufacturer provides compared to the OEM measurements they provide.
