For a regular 97 C280 W202, I'm seeing regular and sport upper control arms. Any idea what the differences are? At least the places I've looked so far, the sport is less expensive and much more available.

Also, according to the Dorman numbers, the 96 and up E320 W210 uses the same upper arm, can anyone confirm?

Here are some numbers to compare. I can't come up with any non sport numbers at the moment. ( Also, the Moog R series looks to be a low line part not the usual high quality stuff they make. )

Front Left Upper; w/Sport Pkg.
