the problem isnt when they are first put in. it is down the road after you have been thrashing on the car in the twisties. You will probably start to get deflection and distortion and probably a crack or two.
then again,... if the car was drivin like any civilized person (yah right) and not much weight was ever put in the car (mainly the back area), there would prolly not be a problem untill maybe 10 years later.

I am looking into other options, ways to modify the spring perch and such.
