Most respond best to Poly, ESPECIALLY the rear triangulation mount. Then you need to sort the ride height, in most cases your going to have to bin the springs and fit some that lift the ride height back nearer to standard than most owners have them.
For dampers, on a roadcar, you cant beat Koni. If you get talked into adjustable platforms then make sure you do actually get them setup by weight, not setup so they look good. LOL
Importantly, make sure all 4 tyres are not only the same, but decent. Nankang ditchfinders are not going to do you any favours in the handling department.
For those with a larger budget, a nice pair of chassis bars from Danny at Adrenelain and a 6deg rear beam will complete the transformation.
Put all that together with the price of a clean car your eaily looking at 10/11k then add mechanical reliability to get the average maintaned saff as good as a m3 theres probably another 1/3k
