Ohlins, KW, M3LCA or combo?

I was considering the m4 LCA upgrade for my f22 m240i, but now wondering if Ohlins or KW coil overs may be a better option. Or is it worth doing the LCA and coil overs? Price excluded here, what would you do?

I may do a track day or two, or a drag race for fun, but enjoy spirited driving in the country. If that matters. This is also a daily, but I'm ok with some harshness. Suspension is currently adaptive too. Which makes everything more pricey but again, excluding price.

See my signature.

The coilover kit includes camber plates. The car has 2.n of negative camber front and rear. The setup is extremely effective for spirited and track driving. The limited slip differential and aluminum rear subframe bushings help quite a bit with that.

I recently added the H&R front swaybar to the list.

I went with Ohlins and Vorshlag camber plates and kept stock LCAs.
The M3 LCA limits how wide you can go with front wheels.
Mine was also adaptive which I got coded out.

How do you like them? What was your install cost?

Thanks!!

I love them. I went with different swift springs than what comes with the kit though, harder on the front, softer on the rear.


Install cost was the same as any coilovers, plus alignment.
I bought them from HP Autosport and he sent them with the front struts already assembled with the swift springs and camber plates.
I'm in Australia so labour costs probably aren't comparable.

Coilover with camber plates means you don't have to go the M LCA route for more negative camber or add the thrust arm with spacers to avoid the tire running on the front wheel liner. If you want a more precise handling Whiteline and SPL both make a good adjustable bushing/bearing for the thrust arm.

TCKR and Ohlins are both good choices for coilovers.

Are Ohlins available for an 18 m240i? I've been looking around online and can't seem to find anything. I have adaptive suspension but would probably opt to code it out.

The F30 kit will work but I would recommend a softer rear spring.

Ohlins provide a 16kg rear spring which made the car not very nice to drive on the road in my opinion.
I went with a 12kgs swift spring on the rear and 7kg on the front.

This is some spring info I put together.

Thanks! I'll keep this in mind if I move forward with it.
