What do you think of BC sub-tank

OhYeah

My apologize, We call it sub- tank in my country. I didnt know it has a name BC ERs. ^^"

-How did you guys adjust the valve between Front and Rear? how many click?

Is BC ERs a lot better than the old one from the car??

- Is it as good as KW, TEIN and Ohlin?

As for adjustments, it all depends on personal preference.....
On the "off the shelf" BC Racing ER (external reservoir) coilovers with the standard 8K 10k springs for the 370Z I would run a little softer compression settings and a little stiffer rebound settings. It makes for a nice controlled feel with not too harsh of a ride.

For the street, maybe run most of the way soft on compression and about in the middle of the settings for the rebound.

For track use and aggressive driving, just keep about the same ratio but go a bit stiffer on both compression and rebound... It really all depends on your supporting suspension modifications, your alignment settings, and basically personal preferences.

I work with and have worked with many suspension and coilover companies. I have tested, used, installed just about most of the coilover brands out there available for these Z's and.... for the price range..... I would put the BC Racing coilovers up against most of the other coilovers you have mentioned (and several that you didn't mention).
Both the BC Racing BR (standard coilover) and the ER (remote reservoir) are well made and should suit you well. It is one of only a few brands of coilovers I would highly recommend.

If you are looking for a better, more refined, tailor made BC Racing coilover with lighter weight, more accurate springs, more adjustment range, and better valving.... Might I suggest our Relentless Autosports custom spec'd and valved version of BC Racing coilovers that are valved and spec'd specifically for your liking and needs.
