2012 2013 suspension upgrade compatibility

[specizripn]

So I was looking around Vans site and I notice the Griggs suspension package that drops an outstanding 280 lbs from underneath the car. Now this would be an incredible performance gain Id imagine, but the 2013 car has a redesigned suspension, but how much of it is redesigned? For instance, how many of the parts from one of those kits are compatible, and will there be kits for the 13s offering similar performance gains? Thanks
