Hey guys. Just looking for some advice. Like the title says, I'm looking to grab some coils in the next couple of months, but I'm struggling to find specifics for what will fit. I did search the forums and what I found was BC BR type V-02. I had BCs on my Maxima and I loved them, so I'm getting them again.

Just wanna confirm that the V-02 is the right one to get.

Thanks in advance for any help!

 

You want the BC BR series...not sure where you got the V-02 from, check the vendor section and order from assaulttech, don't think anyone is beating their price.

 

I've heard that Swift Springs are the best. How do they compare to BC coilovers?

 

V02 is just the version, not part number. You will want to get the kit for g37's.

If you can swing it, go for the swift spring upgrade, it is absolutely worth it. I just upgraded mine 41k miles after having the bc's on. If you plan on raising back to oem height at any time, get the longer rear springs... 235mm or more.

The newest verion of the BRs have rear adjustments at the top of the shock, on the outside, so no more drilling to get the adjustment extenders in, but you do have to raise the car to do it. The strut adjustment is the same.

I originally had 12/8k but after switching to the Swift 10/6k, I realized how stiff the former was. Makes sense since 12/8 is recommended for the heavier g37s.

If I could do it all over again, for decent drop and comfort, I'd go 8/6, 8/5 or 7/6.

 

Btw, the swifts are a couple lbs lighter than the bc coils. Try contacting Charles with b2auto in the vendors section. He has great prices and a nice fella to work with. Or you can contact Sam or Cody directly with BC.

 

This is directly from BC's site, and where I got the V-02 from.



Just wanna make sure this is the kit to get.

 

how about some stance gr+ i got a set brand new in box.

 

Yep, you can go by the V-02 #, probably a safer bet that it will fit. Some vendors will still confuse our 2nd gen G35 as a 1st gen and may send you that part instead.

 

Thanks for the help, man!

Any advice on what vendors are likely to NOT screw up the order?

 

Welcome.

I went with B2AutoDesigns myself.

p.s. Welcome, fellow Maxima.org'er

 

I just put tein street series in my 08 g35s with niche nurburg 20x10.5 all around and it rides better than stock by far

 

What application is this for? I haven't really seen much reliable information one way or another on the bc br system.

I would probably stick to reputable well tested companies such as koni, bilstein, or ohlins and stay away from japanese/taiwanese manufacturers unless you have reliable data on the companies.

suspension is pretty complicated. I wouldn't trust 99% of the comments you see on the internet based off people's butt dynos.

 

There's tons about the BC, but yes, from fellow enthusiasts using them. Including those who took the time out to have them dyno'd.

They are reputable, but don't knock japanese and taiwanese manufacturers. BC has been in business since 1999. I think any company that sells as many products as they do and lasts a few years is worth looking into.

Agreed on your third point, yay or nay. But then, what would you go by? Have you seen any reputable, professional reviews of the Koni, Ohlins and Bilstein for the V36 platform?

 

I haven't been able to find much about the bc br system specifically for the v36, but everything i've seen has been fairly consistent.

here are some shock dynos for bc racing's higher end er series on an sti. I am terrible at reading shock dynos, and don't know what the values should be for an sti, but they appear to be fairly linear without a knee which will give you either too little low speed damping or too much high speed damping, and the left and right have pretty significant mismatch. I think the solid red is an example of an ideal plot, with 75% critical low speed damping and 30% critical high speed damping in bound with a knee at 4in/s, and 30% damping in rebound.

I can't find any shock dynos left of the br series (dead links), but all the comments seem to suggest they show similar properties, ie overdamped

what nice plots look like, plus some good general reading

People expect a big difference and a bone jarring ride when they buy new shocks, so that's what the budget coil-over companies make to please the clients, and why you see so many favorable reviews of all sorts of crap. BC is a taiwanese company that makes a lot of brands of shocks, none of which I have seen reliable favorable independent dyno plots.

If your application is to make yourself feel like you did something to your car, are more interested in form rather than function, and/or want to make your passengers nauseated, then bc racing might be the coilovers for you.

I haven't seen anything specifically for the v36, but most dyno plots of koni, bilstein (except for the pss9/10 adjuster), ohlins have been pretty favorable. moton and JRZ have great reputations, but they are super expensive.
