Thoughts or feedback on BC coilovers ... ?
I don't mean this as a negative (don't want to scare anyone off), but the top of the front strut and camber plate remind me of the same on my Megans (which, by the way, I really like now that I have the spring rates right).

Megan Racing:

That aside, I've never heard of the brand. They have nice features, but the 8 kg/mm (front and rear) springs make me wonder.

Research, development, and design generally don't happen at the factory. The factory simply receives a set of engineering specifications and tolerances, and their only responsibility is to manufacture the parts to the specifications given, within the tolerances allowed, at or below the promised price. The design could be crap, but if the factory produces the parts to spec and within tolerances, they've done their job.
Even if that's true, it doesn't necessarily imply anything about the quality of the parts one way or the other.

The saying also goes that this factory is making products for Apexi as well. Apexi is a well established name in the Japanese tuning world and they make good products.
Also, IMO after reading all the comments on the Megans ... no one mentioned any reliability issues, only shock travel problems and only if the car was lowered too a lot. Shock travel will often be compromised if the shock length can be adjusted. So my conclusion is that the Megans performes were well within a certain range!
The BC Racing BR series is on the level of the Tein Flex/KW Variant, not to be compared with the...how shall i say..."Other" models. The difference in piston size is 46mm when compared to the old 44mm design (53mm externally). These also have a large body as well as the lower lock was designed to prevent coming undone which is the downfall of the "other" models. I have sold the megans in the past and I'm no rocket scientist, but just the differences visually when comparing the two are huge, BC is just plain Beefy! In any event, BC makes a great coilover, backs it up with a great warranty. check out www.nasioc.com nothing but happy customers on the BR series. We've been selling between 1-3 kits per day on a steady basis, so i expect the reviews to come pouring in shortly. BC makes a high quality product, and im proud to be able to offer a nice discount on them. So in short its great suspension at a great price. Drawbacks? None, as your covered. these are meant for the daily driver who takes their mini to the auto-x/track on the weekend. they have great street manners, while giving you the ability to take your vehicles handling to the limit.
I've spoken directly with BC North America, and I have a feeling they will be chiming in later

josh,
the pictures on your website appear to be generic; do you have pictures of the actual mini set?
what are the materials of the attach fittings and of the inner body or housing?
thanks
[edited to add] and of course (how could i forget?), what is the lowering range

god, so many choices. Now I'm confused. How is one to decide??
I want a reasonable price for some coilovers that you can take to the track once in a while and still be comfy for everyday street driving.
My price range? around $1,200.00

IMO the difference between the BC and Megan will not be huge, I expect the shock travel to be the same for both.
Main difference would be the front spring rate, 8K for the BC, whereas Megan made an initial mistake by going for a lowere spring rate.

The travel is what many did not like

Any one knoe what the travel is on Megan ?
ps pics are DEFINATELY for the mini...your just used to seeing the old style which dont have rear top hats hehe
I have a nice side by side photo which will be posted later tonight or tomorrow...whenever i have authorization from BC
why do you say they are DEFINATELY NOT MINI coilovers?

100mm...13mm = 1/2" so these posses 3.84" of travel. Next question, how many inches of travel do the springs posses? I ask because every standard linear rate spring will have less travel than its barrel spring counterpart.
I'm assuming these are rebound adjustable...and that bound changes with some ratio to rebound?
It is very hard to see thru pictures, but the perches appear to be basically identical to the Megans. How much neg camber can be dialed in? The Megans allow 2.2 degrees, not enough for dedicated track work, but certainly enough for the street. The adjustability range looks to be exactly the same as the Megans.
8kg, pretty damn big rate for the street...that kind of control is typically reserved for a track.
I'm possing questions for others, not myself.

IMPORTIMAGE,
I'm asking questions on bahalf of the NAM folks. I understand your latest reply and by no means do I mean to knock the product. However, the Megan have their share of problems and this product looks very similar...I am intimately aware of Megan's shortcomings.
The questions that I posed above are critical...they relate to critical performances if you will.
blissfull,
A spring rate alone guarantees nothing. These are ~460# springs. Higher spring rates for the most part guarantee more control - responsiveness. However, these rates do not guarantee more cornering power for example...infact high spring rates can cause rather abrupt weight transfer, dilute cornering force. Whether or not these rates actually work depends upon valving characterisitics, spring travel, damper travel etc.
IMPORTIMAGE or the manufacturer need to answer these questions. The camber perch appear, with exception to how each end of the triangle is treated, to be exactly the same as Megan perches. And if so, only 2.2 degrees of neg camber can be achieved. Plenty for the street and not enough for the track. So a response of "decent enough" is not good enough. Megan has taught this community to ask for facts. And in my opinion, facts are necessary given the unmistakable visual connection to Megan.
Doesn't mean these don't work, but lets get some info first. Leave the hype out for now...if IMPORTIMAGE has a set of Megans for a pictorial comparison, perhaps a performance comparison is available too...

I forgot to add to the above post; 100mm is the stroke length. how is this measured, on the car at the desired ride height or with the damper in hand? These two measurements will be very different. I suspect that 2" or less is all that can be expected or 52mm when these are installed.
