I was going to buy a set of Bilstien shocks for my 97 t/a. I am lowering it with the following,

Eibach sportline springs
BMR adjustable panhard bar
BMR relocation brackets
BMR lca's
and BMR tubular sfc's

I am wondering if it's necessary to buy different shocks or if the factory ones will be good enough for a year or two (around 10-15000 miles)? My brothers' car is lowered 2" and he's still running the de carbon shocks and it seems to handle well so I'm thinking about saving some money and just sticking with the factory shocks.

Thanks
