I'd love to see it here...that way I don't have to go digging for it!

I have a custom setup on my BC ER's that I had Scott put together for me that I haven't installed. I should be getting Scott's floating rotors fairly soon and at that time I will install both kits. I will let you know how they work out from both an installation and handling/braking point of view. My next track day won't be until October. By the way, I will keep my height as close as I can to factory spec so that I can get by with just alignment.

Here is a little peak at Mozens (I'm sure he won't mind) custom RA valved and spec'd BC Racing ER coilovers sitting here awaiting the springs......They should ship out to him this week....

Scott,

A couple of questions as Coilovers and Sways are my next upgrades.

Are the BC ER shocks adjustable for both high speed and low speed rebound and compression???

Are all of the rear shock adjustments on the external reservoir? I have not even looked at the shock locations on the roadster yet, so I don't know how accessible the inside will be...

No the BC ER type shocks do not have a fast and slow rebound adjustment, short of shocks costing 8K+ I don't know of any that do.

The primary shock adjustment is at the top of shock, both front and rear. Turning the knob adjusts both compression and rebound in unison across 30 steps, you can then fine tune the rebound by adjusting the valve on the external reservoir.

As far as handling and ride go these coilovers are superb. With the shock adjusted at maximum height you get just under a 1" drop (I think I measured about 0.7"), but you can drop at least another inch if desired. Front spring preload is also adjustable. Springs are slightly stiffer than stock but never feel harsh. Dampers have a wide range of adjustability. At full soft the car rides very much like stock, maybe even better. At full stiff it feels very stiff and is very resistant to body roll and weight transfer. The setting I like seems to depend most on what tire I have on. For sticky street tires I like 8 front, 5 rear. At auto-x I turn it up a bit and with NT-01 tires I used 20 front, 15 rear. The stiffer you go the less feedback you get from the chassis when it starts to brake away.

If I was going full track with this setup I would go for stiffer springs and damping to match. But for a daily driven street car that occasionally sees the track I think the default BC rates are perfect.

My only complaint would be that adjusting the ride height is a pain. Any time you want to adjust the ride height you basically have to uninstall the front shock. On the plus side though it makes it very safe as nothing can move. Oh and adjusting the front shock means sticking your hand into a hot very tight space between the top of the strut tower and the chassis brace. They do offer extenders though.

I had the KW V3 and wanted more also and I too did not want a slammed car and I had it to do over again I would get the Robispec KW option and I really wouldn't even consider tein or bc racing or megan or jic or any of those other Japanese companies that think a 10k spring is what every shock needs. We don't have badass roads here in America and need something with some bump and rebound with good stroke for each and a spring that compliments the shock, not over power it.

I wouldn't be so fast to lump BC in with "the others". For an extra $100 you can have whatever springs you want and customized valving to match.

This is why you pick the coilover application for your specific needs. A mono-tube strut with a linear spring is going to behave differently than a twin-tube strut with a progressive spring. Kinda like how you don't ask for a red car when you want a blue car.

You're right about the twin tube vs monotube analogy but if I was getting a monotube I would get something like ast-usa.com. Dampers which are properly valves and sprung. You could be right about the BC dampers but it's hard for me to agree with the feel the Asian dampers usually give.

All I can say is I have the BC and I think the spring rate is about perfect for a street/HPDE setup. For an all out track monster you would probably want stiffer springs (check Travis's build thread). I wouldn't even begin to compare them to the likes of Megan, their spring to damper rates are way off from what I here.
