REVIEW: KW Street Comfort Suspension + M3 Bits

ashmostro · 03-12-2015, 09:45 AM

And the clicking sounds like top mounts that need to be cleaned of grit. Do you have standard OEM style top mounts, or aftermarket camber plates?

Stock top mounts.

Fixed the rear suspension squeak, wasn't the shock mounts...
turned out to be the ball joint (driver side) on the camber arm, item 3...apparently its very common

Looking to do coilovers next. currently i have koni yellows and eibach pro-kit springs.

What's the best price you guys have found on the street comforts?

Got mine from Sonic Tuning around Black Friday. Their prices are pretty competitive.

You may notice I didn't mention the Mfactory LSD shown in the pic. Well, when we cracked open the factory diff, it turned out to be welded

My car is a Feb 2007 build, and based off all the applications charts out there, it was supposed to be bolted. Welded diffs were supposed to start from Mar 2007 for 6MT. So my case proves that the transition period actually starts in February. My car must have been built towards the end of the month. So LSD install is on hold for the time being...

I went through "Diff drama" a few years back. I went through Performance Gearing and what he eventually did for me was upgrade me to a larger 335i diff, with 3.38 gears. Very quiet and awesome lockup, no chatter.

nitehawk : We have brand new bolted 3.08 Ring & Pinions in stock ($599.95 after $200 rebate) if you can't find a good machine shop to do the work for you (would probably cost you more than that anyway)

NocturnalEVO · 04-02-2015, 06:02 PM

I ended up purchasing these coilovers based on your review nitehawk although I probably won't get to throw them in for month or so. thanks!

Hello Everyone,
I know it has been a while since anyone updated this thread. I am very new to this type of a thing and have no clue how to get things right. Read this article and everyone's views and am very excited to get this mod done to my car as the existing suspension is really stiff and uncomfortable.

I had a few questions and which are:

Can this mod be done to a BMW E93 325i - 2009?
If possible can people please send me some links or part number where to get all the m3 bits and the other parts listed in this mod?
Where can I get the following items:
-M3 subframe bushings
-Powerflex Street Diff Bushings
-M3 Guide Rods, Wishbone Links
-Megan Racing Toe Arms
-15mm E93 rear bar.

Struggling to find the right part of the Megan Racing Toe Arms

If people have any alternatives or any other suggestions, your help will be very much appreciated.

PM me if you still need help. I have an E93 and recently went through the entire process of a full suspension upgrade.

He was a one post wonder in June of last yr. I don't think he's been back.

These may be my next coilovers if my BCs keep acting up. How do these compare to the KWv2s since they are i n the same pricerange?

These are a better bet if you don't plan to go super low. These have softer valving but stiffer, linear springs. The V2's don't have as consistent of a response but they still ride well when dumped and these do not.

I have these and was on the fence about them for the first year. I had them too low. I ended up removing my Dinan camber plates and switching to xdrive front strut mounts (shallower). That netted me 19mm more travel up front and it's night and day. I really like them now. I have Dinan RSM too for additional travel.

I might try those front strut mounts. Are you rwd ?

You mind telling me which brand you went with? And was there any changes to install?

No they install exactly the same. I got the OE Lemforder ones from FCP

rvphuerta · 06-17-2024, 09:44 PM

Nice upgrade. Good springs rates. I'm sure it rides well. I went Bilstein B8 with Tein lowering springs, hopefully it rides well. It gives me flat ride.

That will ride well. I’d highly recommend e30 spring perches up front as the tein springs are extremely low. The b8s are a good choice as those springs could use the extra compression damping and the shorter bodies will give a little more travel. Great choice.
