M Coupe/Roadster shock/strut options?
For those that have replaced your shocks/struts on your M Coupe/Roadster and didn't go the coilovers route, is the Bilstein B6 the only option left for us that don't want to lower our ride heights? I've read mixed reviews on the B6, so what's everyone latest opinion with it on our MC/MR?
I'm a newb when it comes to suspension. This is just a street/occasional canyon run car - is it worth it to take the plunge and get the PSS10? My only hesitation on the PSS10 is that it has at least a 0.5 inch drop, which I really don't want. How often would you need to rebuild a set of coilover?

Correct
B4 is OE B6 is OE but sportier valving B8 is meant to be paired with lowering springs I don’t think they offer B4 for the M so only option is b6 if sticking to factory springs |

Similar for the fronts, lots of adjustability there, and easy to run stock ride height if you desire. You will see in item listings for the PSS10 kit -0.5" to -1.3" ride height, in my experience so far with it, that is not accurate.

The B16 PSS10 have internal bump stops front and rear, correct? No need for the OE external bump stops? Thanks.

I have B6s with stock springs and love it. Not too firm, not too soft - just right. Handles great, but compliant enough to use as a daily driver as well

I think the B16 PSS10 have internal bump stops front and rear, so I won't need the OE external bump stops on both front and rear, correct? Thanks. Thanks for the feedback. How often do you end up crashing into the bump stop/bottoming out with the B6s? More or less often than stock? Or about the same? I've heard mixed reviews about the B6s - some says they bottom out a lot and others are quite happy like yourself without any complaints on hitting the bump stops

I've had B6 and H&R springs and they handled pretty well after I replaced completely shot stock suspension. I've taken the car to the track and it was decent too. They go over small bumps absolutely fine. However this suspension gets a bit unsettled when pushed harder, crashes when you drive into deeper pot holes (that is with lowering springs), and overall lacks composure. Might be different with stock springs though as you have more travel.
I would recommend proper coil-over kit. KW V3, PSS 10 or Ground Control to name a couple. GC are a very good value and you can basically customize it by ordering any spring rates you want as they come with Eibach ERS springs made to order. Koni shocks are adjustable so you can dial them down to full soft if you want. No crashing, full travel. Comfy with lower spring rates. Plus unlike PSS or KW for example you get linear springs which means consistency throughout travel range. And on top of this you get very nice camber plates. Also, Koni shocks are well known to last for a long time. KW V3 although an absolutely awesome kit, do need to be rebuild once in a while. Not sure about the Bilstein PSS. Anyhow, I think they're all good options but GC wins hands down as far as value for your $ goes. |
