Nah, if they don't have them now they'll never have them. I'm running H&R Sports on stock shocks and, to be honest, the ride is pretty good. Obviously harsher than stock but well within tolerance. If you're considering shocks, I would recommend springing for them. Suspension installs are pricey and you don't want to have to do it twice.
