Do you recommend any shop?
Edit: I have done some more searching.. I think ill keep the torsionbars and add a coilover. Please give some tips on stores and which coilovers that are good.

Lowering the 1303 won't have increased the spring rate so it should not have been stiffer? To give you an indication on the suitable coil spring rate in addition to the torsion bars we need to know the corner weights (are they standard?). I would guess that you probably only want to stiffen the rear by around 30% so the rear coil won't be much more than 100lb/in.
As to suppliers, the list that I gave still applies although if you talk to AVO (who supply LAP) and Spax they will advise a suitable damper rates to go with the coil spring/TB combination. You would be best to talk to their competion department as they are more used to the bespoke set ups. They will need to know the lever arm distances of the TB centre to both the damper bottom mount and to the centreline of the axle to calculate the wheel rate. The standard torsion bars are 22.5mm diameter. For a road car I would recommend poly bushes in the eyes rather than the uniballs to keep the NVH under control.
