Just bought a set of these and thought some of you might be interested.
They usually go for around $700-$800 but Streetsideauto has them for $641.98 and they currently have a $50 off deal bringing them down to $591.98. Use Mr Rebates to get a extra 5% back and that brings them down to $562.38 for the pair!
Not a ton of reviews or info about these on our trucks but Fox has a great reputation and I've always really liked their products on my other toys. For way less than the price of the Bilstein 5100/Toytec setup you can get a set of tunable and rebuild-able Fox coilovers. Seems like a killer deal!
