can someone tell me, S8 suspension

[kkswoW12]

on an a8 w12, all d2, what is the difference in the spring weight for the front...i am assuming, i know, not a good idea, why i am asking, that the rears will be about the same wieght wise, so thats not a worry, but the fronts, i think the difference in wieght of the two cars is around 300#, and that is just about all front, all engine, so am i going to be able to see in the ride height the 2 invisible guys sitting on my hood? and wiil the susp be acting differently? never track it, no racing, and i will be gettting new shocks, bilstiens probably, unless some one can steer me to something better, and i don't have to try to go lowball here so, i appreciate any advice given, and there will be a set of KW var1 coilovers all 4 wheels with whatever is there and coming out cause the ride sucks, it looks just right, the rears lower about 50mm and the fronts are adjustable and i think it can go 55mm +/-, thanks in advance, kevin,i am in germany, should i just go to audi to buy the S8 parts?, don;t think so, i don't have to cut costs but no reason to pay top dollar either,
