I went with King Springs and Bilstein shocks a couple of years ago for a 2" lift and haven't looked back. This combination has a history of working well in the D1. I have pounded the crap out of them all over Australia and they have withstood the abuse very well. Often there are specials out there that brings the price right down, although not as low as this package. I am sure someone along shortly who can give you some info about this particular eBay setup. Good luck!
