What springs are on there? Have a look through the wheels or from underneath: colour / name / any codes?
Mine had Cooksport springs on when I bought, these lower nicely and handle well. Eibach Sportlines have provided a better compromise as a daily.
In terms of shocks, some Trophy owners are buying the yellow Koni Sport rear shocks as the rear Sachs are out-of-stock. The reason I mention this is that may be moving to the Koni's all round, with matched springs, possibly the Sportlines, would be a good upgrade for you?
I'd speak to Mark Fish (trader on here, or look up online) as he seems to be one of the gurus re: setting up 182s & he recommends the Koni's.
There will be lots of other options though! Recent group buy on Bilstein B14s (have a look in the Car Parts for Sale section), or if you want to splash out, how about some H&R coilovers? Budget, usage & personal preference all come in to play, have a read of the previous discussions on here :up:
