If you want a modern setup that works, you need to speak to AD at VA motorsport. He did have a used set for sale a while ago. Possibly used/period(ish) stuff also.
As Alan pointed out above, i'd go for a nice period setup.
There's a lot BC/TTT type fans on here, however I'd really question what development their stuff has done on a rally spec(or any race spec) car, along with their actual knowledge of that type setup. Rally setups are generally the most complex and expensive suspension setups going. Not an off the shelf Far East, Chinese type setup that people put their own stickers on, claiming that they work with every spring rate going due to having 40000000 clicks on the damper.
