I have a set of BC ER's that I'm giving a go
about 1699 from memory 30 way bump and rebound adjustment, external canisters
the only problem I have found is the spring rates of 8kg is too high for normal street use, I have the adjustment to full soft on both and it is acceptable for street but very little travel
I think a 7/6 or even 6/5 would be better the dampening then could be used to fine tune the car better.
I have removed a set of Ohlins strut style shocks that were absolutly awesome, just reciently rebuilt and tuned so I'm using those as the benchmark.
havent got back on the track with the BC's but I'm very keen too, (due to work commitments)
I think there are lower grade BC that price is better also spring rates are lower too.
for a new set of cheap coil overs they are pretty good value and look the goods.
A full set of drummonds would be better but at over 1 gorilla a corner I think I would need to go pro!
