Custom spring advise please

After 2 failed attempts at getting my 200 lowered, I am looking for new options.

I have already tried H&R springs and KW V1's coilovers and both do not fit my 200. These are designed for the 197 and early 200's which had the larger front suspension bearings.

My 200 is fitted with much smaller diameter bearings which don't suit any springs/coilover kits on the market at the moment.

I am now considering getting some custom springs made to suit my mounts but where would I go for this?

Also I would want to make sure that any new springs do not **** up the handling. I'm not sure what spring rates etc I would need.

Any advise please?

I know it handles great as standard but hate the tractor look, really want to lower it but not screw up the handling

I'm going to drop AST suspension an email on Monday to see if they can help

Cupped cars are hardly tractors fella, they look fine as standard imo (still haven't fitted the V1's yet lol)
