Not heard of them but it would be worth contacting the following bloke who is an expert in suspension parts fitting etc. I took my van down to his workshop in Cannock from Bradford to have a problem sorted and I was very impressed with the service, well worth the trip.

Heard and read plenty of good reviews on these, although the ones I've seen were nearer £250 to £300.

I'm in no way affiliated to CRS, having used them, Steve's knowledge is second to none - he builds suspension for race cars too, so knows his stuff. Great service too.
