bearmach and procomp.landrover 90(1986)

so my springs are looking a bit tired,slight lean on the passenger side,replaced the shocks 2 years ago with armstrong standard oil filled shockers,,anyways have been looking at the bearmach standard height heavy duty springs and pro comp gas shocks,anyone else used this set up?found the springs shocks and heavy duty turret rings for £194 quid including delivery doesnt seem to be a bad price to be honest?although my suspension is sagging at the moment i still have a nice comfy ride on standard springs and shocks.going to order on monday so any advice or comments ?thanks..
