I don't mind the M Performance Suspension kit not lowering the car by that much. Extreme drops come at the expensive of drivability and performance. This is probably why BMW, Ohlins, and AST recommend only a 10mm drop beyond the 704 Sport suspension.

Yes, it's the optimum rate of drop for this vehicle. Firmed up, yes. Still relatively smooth in most cases. Once I switch from the run-flats that'll make it a little smoother.

Just read the M2 M performance suspension is made by KW.
http://blog.**********s.com/quick-sn...tails-modauto/ EDIT: link's blocked but that was on Mod Bargain's blog today. Wondering if the 3 series is from them too, would make sense. Anyway, i'm very happy with my KW DDC set now that i've softened by anti roll bars

Not sure why but this looks my bilstein-ish than KW-ish
As a comparison, the M4 GTS definitely look like (and are) KWs without the branding.

Also live in Houston and curious as well.
One question, total newbie when it comes to springs/suspensions, how come this one (link below) is so much more cheaper than getbmwparts....$380 vs $1500 https://www.bmwpartspros.com/partloc...catalogid=8798 Also BMW website has it at $980, I know both BMW website and bmwpartspro doesnt include spring in price, but cant be that much different |

"hardware not included." That price they have listed is close to what the springs themselves cost, nothing else.

I attempted to install my M Performance Suspension yesterday but experienced a fail along the way so I'll be attempting it again in approximately 2 weeks. The short story is that I applied the wrong torque setting to the hex bolts that fasten the front top hat to the strut tower. My car originally came with M10 (steel) bolts that are spec'd to 41 ft. lbs. + 90 degrees. The M Performance Suspension kit comes with the weaker M8 (aluminum) bolts that are spec'd to 21 ft. lbs. + 90 degrees. The M8 bolts sheared off inside the top mount and I had to spend an extra hour or two dissembling the front spring/strut assembling and extracting the partial bolt.
Regardless, here's a few items that you may want to order since the M Performance Suspension kit doesn't have or doesn't have enough of if your install doesn't go perfect: - Strut bar to strut tower Torx bolt - Extra M8/M10 top-hat (guide support) to strut tower bolts - Sway bar to strut nut - Steering knucke bolt + nut - M12 self-locking collar nut (if you somehow need to disassemble the front spring strut assembly, you'll need a new nut and these are also used in the rear to secure bottom of strut to control arm) - Hex screw + self locking collar nut (secures rear control arms to wheel carrier) Quote:
