Need spring opinions. Swift vs. B&G.

I have EDC if it makes a difference.

I've also read from several people about the HAS hitting really hard over big bumps. Wonder the truth to that.

I also wonder if you can do the e36 bumpstops in increase the travel to prevent that.

Here is what mine looks like with the Swift's on:




Sorry for the crappy iPhone pictures, wanted to get them quickly. I showed these pictures to Swift and they said this was normal. Doesn't seem normal with what I've been seeing on the forum. Also this has 15mm spacers on the front and 12mm on the rear. Super annoying.

I thought that I saw somewhere that B&G made the springs that Dinan sells? I have the Dinan springs and I'm very happy with them if that translates over to B&G. One of the best things I've done to the car.

There's also lots of talk that Eibach makes Dinan springs all of which have been unconfirmed.

Spacers are 15mm front and 12mm rear. Bridgestone RE-71R 255/35/19 Front and 275/35/19 rear.

Crashy as in hitting bumpstops on big bumps. Basically, if I don't notice a big bump and go over it at anything around 35-40mph I am going max out the stroke that is left on the strut.

On the lowering, keep in mind I'm on a 19" setup as well.

Hi gents, new to the forum. Just picked up a 2011 ZCP and looking into lowering it a bit. I have been researching and have also narrowed it down to Swift vs B&G.

Never owned either, I have heard of Swift from the ClubLexus community, but B&G is new to me. I am open to either and have owned both progressive and linear springs in the past. They both have their pros and cons.

The question I really have, is the drop the same with both springs? I see both state 1.0" front, but some are saying they didn't get that or their one drops more than the other? (I do understand it will not drop a ZCP a full inch) Since reviews for both have been so good, I would lean toward whichever one drops the front more. Thanks.

my understanding zcp suspension drops less after you switch springs. swift and b&g have similar drop but b&g drops slightly less in the back.
hope that helps

I recently installed the Swift after months of research. The most common con i've seen for Swift is that it doesn't lower the front enough. I completely disagree. I was really surprised by the drop because most, if not all, of the comments suggested that it would give a conservative drop. My front gap is nearly gone. I also swapped for e36 bump stops. I'm so low I don't think I would be able to get 15mm front and 12mm rear without rub.

Man that looks good^

if i go with b&g springs will i need the e36 bumpstops? are they really that necessary?

I have B&G without e36 bumpstops. Been on them for over 6 months now and I don't see any issues.

I am running the B&G springs on my e90m3 with EDC and 19" BBS wheels. I find that over time (3mo) the drop has come down to the point where the fenders are just at the tires, which looks great. However, the ride is alot more harsh, very bouncy, and bottoms out even though i trimmed the bumpstops. If i dial up the EDC the ride gets even more bouncy.

Granted i live in SF, and the roads are not great, but also not the worst i have seen. At this point with my m3 being my DD, i am considering going KW V1 for more comfort...

Get the E36 M3 bump stops. That additional travel makes a world of a difference.

Here's mine on H&R Sport Plus and it has never, ever bottomed out on even the nastiest of roads and deep potholes. Rides extremely taught and sharp, I can't imagine a better driving/sitting spring setup for this car.
