- - Swift springs or br bc coilovers? (http://www.the370z.com/brakes-suspension/55960-swift-springs-br-bc-coilovers.html)

I've been super pleased with the BC-ER's on track, over 3000 track miles on some very suspension abusing tracks and no problems. Granted these are a notch up from the base BR's but aside from the external reservoir and extra adjustment I think the basic construction is the same.

The ER's in particular with the 12K/10K springs are probably not the best choice for the street (you can get them with swift springs optionally) but I imagine with 10K/8K springs on the BR's the street ride is quite reasonable, although probably not quite as good as KW's for street. Myself and plenty of others are using BC's for Time Attack and couldn't be happier.

But since you are street focused and on a budget your options are a bit limited. Remember that lowering much more than about 1" will require aftermarket front and rear control arms/links to get camber back within spec. Swift should get you as low as you can go before you have to do that, maybe check out a local car that has them to see if it is low enough for you?

If your goal is to just lower your car, then sure I guess they're okay. But for performance? They aren't good. They're likely even worse than stock.

No one who actually knows suspensions would ever recommend them. Yes, BC ERs are okay for track use, but that's an entirely different animal. BC BRs are just not performance coilovers. They're just the go-to "forum brand" that a lot of people who hard park their cars use.

Also, while I've never used them personally, my buddy was running them on his Forester. One shock failed after less than 2k miles.

:icon18: 100% guarantee that shock failed because he didn't set the load correctly and put all the energy into the absorber instead of the coil. Happens all the time. Don't bash em if you've never tried em.

Over the winter I might send the rear springs back to them to be checked for spring rate and see if I can get something a bit softer... the front is set almost fully on firm and feels nice and planted... the rear just seems like it doesn't have enough weight (as I stated I have a G37 kit which was made for a heavier rear setup).

I don't think anyone is denying that the Swifts are nice springs, they just don't give you enough drop. Any time you lower the car you are generally going to compromise some ride "comfort"... just a matter of how much you are willing to deal with for the given drop. For the money, quality and adjustibility I found the BCs to be a pretty descent option.

I'd still consider used KWs or something of that nature if you truly have a $1,500 budget.

You can GOOGLE anything and you are bound to find something that breaks. NO parts are invincible regardless of how MUCH you spend on it.

So posting a link to a Mazda forum, that shows a guy having issues with his coilovers and stating that he was aware that he was driving around on a shock that was blown, is moot... right?

I just don't see how you can justify calling BC coils "crap" when you have no direct experiences with them, nor have been in or driven a car that has them.

Sounds like we have a good ole case of,
