According to a mechanic, all of my four L spec Bilsteins are done after about 25,000 miles causing cupping or rounding on all my Toyo Proxe IIs. Need to replace everything. Does that make sense or should I get a second opinion? If the damage is done, should I stick with the same old bilstein shocks or try the newer Hotchkis tuned 2.1 shocks? Anyone have experience with them? I see there are some Proxe IIIs out now as well.
