Has anyone used Guy Ankeny's valving?
I need them to be more compliant over bumps, my setup right now is much harder to drive than the stock shocks on anything other than a perfectly smooth lot.

Does anyone have any experience with BC Racing's ER Series coilovers? They look awesome on paper (mono tube, external reservoirs, double adjustable for compression and rebound, cheap)
Forgot to mention that a buddy of mine, who races with NASA and has been instructing at various tracks for years had an opportunity to drive a 370Z with these coilovers, and was very impressed with them.

Firstly, you should be aware that BC racing stands for Bor-Chuann Racing and is Taiwanese. All of their stuff is made and built in Taiwan. That's worrisome for obvious reasons.
I spent quite some time trying to get in touch with someone technical there to answer some questions. I sent off a bunch of emails to their tech support. I did finally get a response after contacting their main distributor and having him contact them. That response is copied below if you're interested in what I was asking about.
That was a little over a month ago and he still has not gotten back to me about the particulars he said he'd get back to me about (most notably the dyno plot). I also do not like that they cannot revalve (they actually don't even rebuild, they just sell you new cartridges, which is a big red flag to me).
I have no hands-on experience with them, but hopefully this info helps you.
Below are the answers to some of your questions I am curently working on getting a dyno plot for you from my overseas office and also finding out if there is a charger to get a plot of your specific kit. Things are running a little slow w SEMA coming up and I apologize for the delay but I will get back to you asap.
1) Can you send a shock dyno plot, preferably with a couple different adjustment settings? Also I'm very interested in the low speed range so hopefully that's on the dyno chart.
Working on it waiting to hear back from R&D
2) What springs do they come with?
We supply our own springs but can also supply them with Swift springs for an upgraded price. Additional $280 with out our springs. the springs 62 is the ID in mm 200 is the length in mm and the spring rate is 10k. Rears would be 180mm length and 12k rate.
Can I do custom spring rates? Yes
If so what spring rate range can they handle?
You can go 2k higher or lower than default but can be valved at whichever rate desired pretty much up to 16k
What diameter and length would the springs be if I wanted to get my own springs later?
Answered that above but the ID on Swift is 65mm those do work with our setup as thats what we use on our RTA g35
3) Can you tell me about rebuild/revalve support in the US (I'm in Pennsylvania)? How much does a rebuild or revalve cost?
In order to reduce downtime we do note revalve existing cartridges we replace them. On the ER setup the lower mount is included so each corner (cartridge and lower mount) will e $250
If I were to get the shocks, and were to find that I wanted some different damping characteristic (for example more low speed compression vs. high speed compression or something like that), would it be possible to do a custom revalve like that?
At the moment no
4) I assume at this price point that I will not get dyno plots specific to the exact shocks that I buy if I were to purchase, but I figure I'll ask anyway just in case. Is it possible to do this, possibly for an extra fee?
Working on that too
5) I'm having trouble finding these from a retailer. Do you know of an online retailer or local retailer to PA that carries them so I can figure out what the actual street price is?
ER MAP pricing is $1850

Thanks for posting that!
It seems a bit contradictory that he said the springs are 10K front and 12K rear, since the documentation I found shows 10K all around. I'm also surprised there is such a big price increase for Swift springs. Are Swift springs that much better?

Swift springs are supposedly super light compared to others, they have their patented process that uses less coils. Also, if they're using crap chinese springs, then it'd definitely be worth it. It does seem like a lot though when you can buy a set of swift springs for around $80/spring, so you're only getting a small credit for their springs, which makes me think that they are indeed cheap chinese springs.

BTW you can specify the spring rates for no upgrade cost. I think you're right that the standard ones are supposed to be 10k/10k but it doesn't really matter since they ask what you want anyway.

I would not touch these. You won't get much low speed adjustment authority with a DA mono tube anyway, which you seem to indicate you are interested in. It's obvious to me that these are just cheap, and for STR you need a shock that can do its job correctly, not just looking cool slammed. For STR, you probably want to play with spring rates, so I also don't like coilovers that don't have a lot of spring options. No dyno, forget it.
