BC BR Suspension
 

So I know that 370z/g37 coil-overs are compatible, but my concern is the info on the box. It says 07+ but g37 first came out in 08? Also I went to the website and looked at their applications with the chassis code and all that and they don't match up at all.So should I have any problems trying to put these on?http://i284.photobucket.com/albums/l...psa3b494de.jpg

BCBR=:facepalm:

You should be ok though.

Really? I just checked my box and it says 08+ Fair Lady Z/370Z.

Where did you buy this anyway? Ebay?

I just don't think they're top quality coils tbh. they're just mehh

I've had them on my car for maybe 300 miles now. I really don't notice a difference but I haven't played with it yet. It sounds really heavy when the back hits speed bumps and it tends to respond better if I go around 10-15mph. I got them because I had tanabe springs and the car was too low. The way the tanabe felt was good but it scraped everywhere. I don't know how well I trust the guy who installed it either...

I'm interested to see what your experience will be with it.

In their price range I would put them near the top of their category. Good customer service, quality build, pretty easy install,custom valving included, swift spring upgrade at small fee. In your ~1000.00 1-way category You would have to shop in the 3K+ range to beat them imo.

interested in your opinion of them and why? I bought a set last summer and now that they are dialed in I can't say I could have spent 1K better unless I would have just saved it for 2 ways.

Well stated...

I feel the complete opposite. Nothing noticeable has happened except now when I go over bumpy roads or speed bumps I hear a heavy thuds from the back that worry me

I just ordered a set of these, myself. I have been told by people they have really liked their BC BR coilovers and have seen great things online about them.

I think most people, like myself, understand that you can purchase a better set of coilovers but you will obviously spend more money. If you can afford it or you plan to track the car frequently, spending $2,000 or more on suspension is justifiable. But if it's a daily driven car that might see a track day or two and be driven on public roads, enjoyably, I don't see the problem with these coilovers just yet.

But like anything else, no matter what community/forum I have been apart of, there is the crowd who swear by the more expensive/better performing product and because of this, anything but that is unacceptable. Just because the entry level BC's aren't as effective as the KW's or another brand you swear by, doesn't make it a waste of money or "crappy coilovers".

I ran Megan EZ Streets on my Accord Coupe before my 370Z, as did probably 70% or so of the lowered Accord community. Everyone liked them there; no one really cares for them here. Those, too, were great coilovers I got compliments on ride quality for but, sure, I could have had a better setup elsewhere with more money spent.

To each their own! :tiphat:

You have to understand that there is a reason why they are so cheap lol, all of the coils are easy to install and quality has nothing to do with customer service. Besides lowering the car there doesn't seem to be much difference in handling at all, so why spend so much just to lower the car. For sure you cant track on these properly. Not to mention all those noises from the suspension when you go over bumps. ( well you get the point, you can track them but what im trying to say is that they're not very good if you are a track junkie) . Coil overs are upgraded to improve handling and I don't think these have so much of a difference. Rather add another couple hundred bucks and get a used set of KWV3s my :twocents:

Who else makes Coilovers for 1K? a brand that isn't total garbage. but I agree for the price they are justifiable

Kat do you track your car is it DD? Also interested to know if you took the swift spring upgrade/custom valving? I have heard the springs that come with it are not so great. DO you know what spring rates you run? Coils do definitely creak and moan a bit more, but it could also be a sway bar problem.

Well I agree and disagree with some things you have said. For a daily driven car, sways will make much more difference in the "feel" of the ride than coils. Also if a smoother ride is what you want, I would say coils with linear springs is not the way to go. BC is a entry level track/performance coilover and for that application I would say it is a great buy. If I wanted a smoother ride overall, I definitely would have gone koni/swift spec-R setup. But my goal is building a track car and maybe getting something that gets 40 miles ag allon to get to work by the end of this year.

I track at least twice a month these days, and even though it has taken me 5+ months to dial in my rates on the BC's, I am very impressed with what the BC's have done and how well they can dampen track level conditions for their price.

Don't confuse that with having a nice soft, buttery ride on the way to work- I don't. A linear spring on a racing damper isn't supposed to be nice and smooth-it is supposed to handle extreme turns and weight changes etc.

The KW v1 and V3 are both going to deliver a smoother daily driver ride period. They have progressive springs that do a much better job of absorbing the little bumps and cracks of daily/street driving than a linear spring could ever hope to do. That is what they are designed to do, and they do it quite well.

But as a entry level track coilover that performs, I would definitely say the BC's are ultimately the better track choice than a KW V3, mainly because of the custom valving and the extensive selection of spring rates. As an out of the box silky smooth daily driver coil that does quite well at the track, the V3 is a better choice-but it is also about twice the price.

Honestly I feel like BRs are "Street" coils, compared to the kwv3s on the canyons it was not even close, the BRs definitely lacked in my experience. my neighbor who had a 370z upgraded from BR to V3s in a matter of few months even agreed. I however am happy with your results, they are good coils for the price. I however would get a used pair of v3S for a few hundred bucks more. Cant believe they did good on the track with no issues

comparing canyon roads and road course seem like apples and oranges to me. i'd say, if GSS is indeed running at the track 2 times a month, his experience with the coilovers is very relevant and shouldn't be dismissed so readily. particularly not by an a$$-skidpad/slalom based on canyon driving.

tracks are generally smooth pavement and kept relatively clean. public roads have more imperfections; cracks, potholes, bumps. etc.

linear springs are preferred for the track/racing. the advantage being that they are easier to dial in, and more predictable, because the variable (spring rate) does not change.

progressive springs are better for street. they handle the imperfections better, less jarring, and therefore give a more stable feeling, which in turn makes people feel more confident. if you feel stable and confident you will feel like this coilover is better.

it's probably fair to compare coilovers (in this case the BCs vs KWs) in terms of quality of fit and finish, comfort of ride, whatever, but which one is faster cannot be compared especially when not even talking about the same kind of driving. in track driving you are trying to approach, and have the freedom to approach 10/10. in street driving, you better be shooting for 9/10s since there are just to many variables (leaving aside the fact that you are driving at illegal speeds).

the question remains, if you are going to track the car. which one yields faster lap times? this is difficult to ascertain since the equation is complicated by a lot of other factors (sway bars, tires, alignment, etc.)

so i suppose the point of my comment is... this conversation could go on forever and not reach a *valid* conclusion. however, it is important to note that linear springs are preferred in racing for a reason and that progressive create a better street experience. so it could be argued the KW V3s are street coilovers, while the BC BRs are a track coilover.

I do track at least twice a month. I am starting to get close to what would be considered competitive times in entry level time attack. The KW v3's have been proven on track. Clint Focus on this site who is a much more experienced driver than I and could be consider pro/semi professional skill wise has put it in times on KW v3's that make my times look paltry in the same car on the same track.

That being said I feel the BC's with the correct springs/sways could match them at the track no problem, if not exceed them. However, they will never have the street feel of the KW's. KW's are more of a high performance street setup that does very well at track because they are factory tuned so well. With a little knowledge of bump/rebound, they can be setup to be a very effective track coil-but I don't think that is their primary application.

There is no comparison to a canyon run to being at a track. There is just physically no way you can do on a public road what a car experiences at a real road course-even if you tried(which you should not).

The BC is a racing coil, albeit a low end racing coil, I could understand why someone might not like them for street, but valved and sprung properly for street, they should be fine. I would not expect them to feel quite as smooth as the V3's but at half the price, I have to give them a thumbs up.

My suggestion if you are unhappy with them on street would be to either respring/valve them, or sell them to one of your track buddies and switch to v1's v3's or Koni+SwiftR's. All of which are excellent choices.
