In my experience, and some of the other guys who post on the board, the Tokico Illumina 2 (stiffer upgrade shocks) don't seem to last as long as the original replacement Ford (also manufactured by Tokico) shocks. Not sure of anyone who has tried the Gabriels, looks like they only have ARC-compatible shocks for the front of the SC according to their website application guide.
