Aftermarket Suspension: KW HAS vs Dinan HAS vs Coilovers?
Hey Everyone,
I’m trying to decide between a few suspension options for my 2018 M2. KW HAS kit Dinan HAS kit Mperformance Coilovers Pros and cons of both? Car is not a daily driver but I don’t want a bouncy ride. Thanks!

MSS HAS springs here. I went through the same back and forth just recently; springs vs HAS vs coils. Man if you aren't tracking the car then skip the springs and coils and get the HAS. Don't let any dude on these forums try and tell you that you're an idiot for not dropping 3 grand on coils. Ask them if they're donating to your GoFundMe page for the additional cheese for coils. The HAS are more than capable and compliant for street use. I can tell that these MSS HAS springs have made the ride noticeably more compliant. HAS all day baby. Now it's just a matter of which HAS you want and that depends on how far you wanna drop it. I would get a HAS kit that can get all 4 corners to a minimum of 595mm or 600mm. These are sitting right at 595/600 and they're perfect.
Side note. You absolutely will need spacers if you drop it to the above specifications. It shapes the look when you run 7.5-12mm spacers. The pic I provided is 10mm on all 4 corners. |

I would stay away from most if not all HAS kits…they will prematurely wear out your OEM shocks.
Coilovers without a doubt- they will not only lower the car, but should improve both DD and track experience by allowing you to set your own damping/rebound settings as well. MPS is a super solid choice, but they aren’t easy to adjust on the fly like Bilstein B16…thus the latter was my choice

PS Turner Motorsport makes hubcentric spacers…probably the most recommended spacers out there

Don’t dispute your experience in any way…you make valid point about HAS given where you’re coming from.
Other/some F8x members experienced (thinking of M3/M4 crowds) the total opposite w/ HAS kits, and that made me shy away from them. However, my key point is, there are many forum vendors that can sell you a mid-entry level coilover kit for a few hundred more vs. some HAS kits at msrp, especially if you wait for some deals or holidays discounts. Given all the pros that come with coilover kits vs a static spring kit, it made sense to me. It may make sense to OP as well Sure, a HAS kit will always be more cost effective, but sometimes you do get what you pay for.

OP, despite some subtle bias shown on the previous posts, you inquired re: pro/cons of HAS vs coilover.
I will try to help, so here’s some reading material https://www.autoworks.com.au/blog/29...-struts-shocks Good luck.

I've been very happy with my MPerf Coilovers - on the softer settings it feels almost like stock on the street and is very compliant - the only issue is with the occasional rubbing on huge dips, but that's not the coilover's fault. On the harder settings, it works well for the track (but for serious track work, you'd get something like Ohlins, but they are way too stiff for the street).
That being said, if you never intend on tracking, HAS should be more than adequate. If you blow out your shocks, you just replace them (they're relatively cheap, and even cheaper if you source them from FCPEuro and get lifetime warranty). |
