Having modded an e36 suspension (not my present e36, which is stock) in phases - bilstien shocks & eibach springs, then RD sways, I found that the mild increases in spring rate provided by aftermarket springs do not have a profound affect on roll stifness on an e36 - not nearly the affect that big bars have, because the stock bars are just so damn wimpy (bmw's way of giving the ride some compliance). Thus, I do not think that aftermarket springs (unless you go extremely low/stiff - a full race set-up) absorb much more cornering load than stock M3 springs do. UUC claims the tabs are damaged by big bars coupled with bottoming on large potholes and such, not hard cornering on smooth streets/courses. This makes sense to me because it would seem that the great velocity of a violent one-sided impact would create far more ripping force on the bar tabs than turning into a sweeper, or even a hairpin - which would create a much more gradual building of forces on the tabs and be unlikely to rip/bend the steel.
Just my dos pesos.
