300e Spring Replacement how many miles?

I was driving today and went over a slight rise between streets and scraped my front sway bar. I replaced my motor mounts last summer so it didn't hit my pan.
The car has 210K(89 300e) and previous owner peplaces the struts with SH_TTY Monroes so I know he probably didn't replace the springs.
I just replaced front suspension parts and the handling is much better but could be still be improved. Planning to replace struts shortly.]
Should my springs be shot in 210K ?

Thanks ,
