428i Suspension Suggestions
Putting together modification plans for my M Sport 428i GC. Stock vehicle has M Sport Suspension and wheels are 19in OEM 403's wrapped in Eagle F1 RF (Rear 255/35/19; Front 225/40/19). Looking for input and ideas for future mods. Disclaimer: I am not a racer. I am looking give the vehicle a little aggressive look and handling. Wanting to keep the ride comfort as much as possible. My driveway will not allow me to have a very low vehicle without scrapping. I DO NOT like having to approach speedbumps or driveways completely sideways
-Did some research on the HR Spring and it states that it only lowers the vehicle .5/.6 inches. Has anyone installed these with the MSport suspension? What are your thoughts? Did you replace the shocks as well? -Rims and tires. As much as I would like to buy new rims and tires, I have to wait just a little bit to get the ones that I have been eyeing. With that said, with my current set up would spacers something that I should consider? Pro's and con's on the their applications please. What would be the best make to consider and what size? If I replace the springs I do not want to risk rubbing. I have kids that ride with my all the time therefore the last thing I need is rubbing issue if I have people in the back seat. Thanks for allowing me to ask all these long winded questions. Thanks in advanced for your input and suggestions. |

the likelihood of having problems with just springs is very high and is evident from the numerous threads and posts on here. although some people have not had any problems with just springs, i've read enough on here that have had problems, so my recommendation is to spend money the M-Performance suspension or good coilovers such as Bilstien or KW or Ohlins if you can afford it. nothing worse than problems requiring removal/re-install/alignment multiple times to resolve.
on my 2015 428i Gran Coupe i went with M-Performance suspension which offers a 10mm drop from M-Sport height and damped for much better handling. do your homework as M-Performance is not offered for Gran Coupe however I took a chance with the pre-Jan 2015 kit and it all worked out, straight swap, no problems whatsoever. the strut mount may be different on the from-Jan 2015-on kit so you may need that one. not sure why the pre is $200 cheaper... https://www.getbmwparts.com/partloca...catalogid=4462 https://www.getbmwparts.com/partloca...catalogid=4462 |

The only one that I found is the HR Sports springs that states will lower a M Sport Suspension equipped F36 by .5/.6. |

i've seen more problems with H&R springs than any other on here even though it has been R&D'd for specific vehicle. anytime you lower the car with just springs the stock strut usually wears prematurely and eventually bottoms out from additional preload and unmatched damping. you can do the Dinan cut bumpstop thing to help out with that. that is my opinion/recommendation but do as you wish Last edited by alohasurftoad; 07-21-2016 at 04:29 PM.. |

Hmmmm.....let me double check. I thought the only options were the M Sport Suspension and the Adaptive M Suspension. This is why I ask the question cuz I have no clue

After reading and reading other post regarding suspension I ran across AC Schnitzer. They have a GC Specific coil and full suspension set up. Does anyone have the sport suspension kit installed?
