Have used MSW a couple of times, decent retailer.
Europerformance and Balance Motorsport are worth comparing prices for KW range too.
I liked the KW3 - had them along with a lot of other work, on the S2000.
After days of testing on road and track I arrived at a good compromise setting on compression and rebound.
It was exactly as they were shipped from Germany LOL!!!
No experience of the v1, but a stainless body and excellent build quality makes me think they might survive better than some budget models I have seen.
