I had my 350z for almost 14 years and close to 100k miles. Unlike most of them out there, I never touched the suspension. I fixed the understeer that car naturally has by fitting 20mm wider tires up front. When I finally got rid of it, it still felt as good as new, suspension compressions and bumps would be dealt with with minimal bouncing, and everything still felt tight, with a ton of travel. I pounded that car around corners and even beat on it on gravel roads. There’s something to be said for not messing with a thing that isn’t broken.
That said, my lemons car has cut springs at all four corners, the absolute shittiest possible way to lower a car. We didn’t even bother to take the front springs off the car when we went in there and cut them. And you know what? It handles like a fucking dream. We probably have around 75 hours of track time on that setup. Sometimes shit just works. |

Have driven both the M2 LCI and M2C with standard and lowering springs and I prefer how it handles/feels with Eibach mounted. Have done a wheel alignment after both installs of course to get the most out of the modification. |

Unless you go back to full stock ride height or may be a few cm down you cannot drive without a care even swells in the road (when going uphill) can bite you. I also cannot visit my mom and drive up the driveway anymore. No problems a few times but then caught under the bumper once. I don't know how these guys slam their cars, it's nerve racking driving around. Luckily the brake mud flap thingys hit first. Some board members told me that you need to learn how to drive with a lowered car but when pushed they all admit to scraping. Dealer tech who installed my MPS told me he's seen many M3/M4s who rip off the brake mud flap things. |

Oh and the car does settle. These are picks from a few minutes ago with car sitting in garage all winter. I don't even think I can do 255/275 like I did on stock M2 w/o rubbing though people say I can.

Springs generally don't make your car handle better for a couple reasons - 1. The spring rates are higher than the dampers are valved for, which means the dampers struggle to control movement particularly on rebound. This creates a 'bouncy' feeling. 2. They reduce the shock travel before you hit the bump stops, which effectively massively increases the spring rate. When the shock bottoms out that energy is transferred back through the chassis reducing grip. Suspension travel is key to handling road undulations. I have never seen any evidence of lowering springs improving a well setup car (i.e. an M car). If you want to put springs on for aesthetics go for it, but saying that manufacturers design their cars to be lowered on springs doesn't make sense. |

What you're referring to is aftermarket companies that try to lower a stock car by an inch or more, and in doing so you'll get that bouncy feeling, and destroy the suspension. Look at the many in-house manufacturers spring/damper specs, and notice how little difference there is between them and the stock car, yet they make the car handle better. This is because, with suspension, less is usually more. Merely lowering ANY M car by 10mm will make it handle better, end of story. Of course, it'd take a professional to see that difference. |

If you're happy with the stock setup that's great and you don't need to spend a dime.
If you're just looking for aesthetics than go with a HAS kit over lowering springs. With a HAS kit you'll get the added benefit of height adjustability and the spring rates are better tuned to work with the stock suspension. Yes it cost a bit more than just springs, but it's worth it. If you're looking to increase the cars performance while also getting the benefit of height adjustment for aesthetics get a proper set of coilovers. This option cost the most, but like almost anything in life you get what you pay for. |

Or you can get a driveway like mine and then you'll never lower your car unless you want to park on the street. Makes it easy to not worry about the ride height.

But to be fair, for some reason I also don't think the M2C with the new wheels type (at least in AW) really looks better with a drop. Drop with 437m on OG M2 in BSM looked a lot better and felt a lot more necessary to me back then. Perhaps I'm just finding any reason to sell them at this stage, idk I also have no clue how slammed cars are a thing. Maybe on a track or if you're going to showcase your car, but for regular public road use... It feels like you're placing a handicap on your car, so more of a downgrade than an upgrade. Friend of mine many years ago had a slammed e92 335i and I really noticed the struggle. At the expense of sounding stupid, does it make sense to install coilovers without lowering car height? Seeing as I've never even see someone do this |

Define 'better' handling? Lowering springs alone certainly won't have any effect on lap times. If you have any evidence happy to be persuaded otherwise. You don't appear to have a very nuanced understanding of suspension dynamics if you think lowering any M car 10mm with lowering springs will improve the handling. If you had managed to cobble together an argument around lowering the center of gravity your post may of had some merit. But by all means, put some stiff springs on, declare your car handles like a go cart and be happy with it. |

Though with the M2 that will have the rear shocks almost resting on the bumpstops (info I learnt from a guy who tarmac rallies his M2C & has gone to custom coilovers). Can't see how handling would be improved?

RealOEM shows that the M2 has the same shorter bump stops as the M3 and M4, but different springs and shocks. If what you're saying is true, there really isn't any valid reason to fit lowering springs on the rear without addressing the bump-stop issue.
