Does anyone have a diagram of the CSL damper / spring assemblies? I would think the springs are much shorter than the standard M4 to accommodate the tender springs thus ruling out existing 'lowering' springs such as H&R. Ideally, they are a standard dimension and rate such that an off-the-shelf Eibach could be used to lower - but I don't think that is the case. It may be a challenge to get a manufacturer to create lowering springs for the CSL given the low numbers. Not sure what JP is up to with KW, I'm assuming a full C/O kit?

KW's R&D is always impressive.

Here's my take on this why would you purchase $140,000 car that Bmw spent who knows how many hours road testing this car to get the suspension dialed in perfectly. Do you think that KW is going to do a better job by throwing the car on a machine and building some lowering springs. I'm sorry guys but if you think that throwing lowering springs on your car is gonna make your car handle better you are not very smart my friend. I don't know why people seem to think after market is always better it's not you're paying for the fact that they brainwash you into thinking you need to lower your car to make it look good. The new Porsche GT3 RS you have to be an absolute crazy person to mess with the suspension on that car Porsche already has lowered it from the factory and it has in car adjustability…. Stop buying M CARS putting lowering springs on them and ruining the suspension and then trade in the car again with jacked up suspension system..

I agree. I've always been impressed by them. I really like Ohlins' and Bilsteins R&D process as well. Even comparing the OEM Ohlins to the aftermarket Ohlins, for example, shows some pretty significant differences between them.

And to answer your question about if the ones from the M4 can be used…very unlikely, as JP asked the guy if you could put the V5 just like that on an normal M4 and the guy said no, damping rates are different and would need sone adjustments before. |

This is an F1 testing machine. He is not putting some lowering springs on it, but basically a GT4 car suspension optimized for track use. They btw are building the suspension for the GT4 for BMW and work very closely with BMW overall. The test machine that KW has its borrowed by manufacturers for testing…so they know very well what they do…they are building specialized suspensions for some decades now, and only that. You overweight the M and car manufacturers…they build a new car in about 4 years in everything that is involved in building a car and do it great. KW spends a year in building a suspension for a car to optimse for specific applications… And car manufacturers often do not build suspensions themself, they let them build for their cars, and guess who makes them? Why should they, if there are companies specialized in all those topics. And, he wants to make the car even quicker on his personal racetrack…he did a timed lap stock and will do another one when suspension is done, so soon you gonna see if its quicker or not. That is the cool thing with JP, he tests his mods with all cars to see if there is improvement or not And he owns and owned some more expensive cars than this, McLarens, GT3, GT3RS just ordered, and all get mods, some more, some less. That's what his business and channel is for |

Beside the fact that you can’t properly wash the car and the wheel well. (OCD guy in here). Otherwise, yeah, some off market probably have a better life span due to exterior treatment and fit and finish of the parts in comparison with a more dull-like oEM. If the factory will offer that, I will upgrade, otherwise NOBODY touches my car. I get the point if visually stays the same and improves overall; is just I hate people working on my cars. The less it sees the shop, the better. |

I agree that for street use you are unlikely to do better, in terms of comfort especially. I think it should be easy to beat them for track performance though. Last edited by chris719; 10-06-2022 at 09:07 PM.. |
