I have a pair of front Koni Special shocks that I have been waiting to put on my '99 G20. I'd like to get the rears, but they're another $250 or so. I'm replacing my shocks strictly because I've got around 98k on the stocks and I'd like to restore the ride quality. I have no suspension mods, and don't desire any performance improvements. Would it be a terrible idea if I were to get a set of GR2s for the rear instead of the Konis, seeing as they're so much cheaper?
