I bought the Monroe Sport lowered shocks earlier this year with ssl kings front and sssl rears and in the last week my front right shock has let go. If you like any sort of handling around corners I'd got the Biltein's as I thought the Monroe's were crap. If you're not going too low and are just after a replacement shock then the Monroe's will be fine. Monroe's are around $200 for the front pair where as Biltein's are around $500-$600 for a pair.
