I am a few months out from making a decision as i am going to replace my tires at the same time and maybe there will be other options. Right now i am leaning towards the EVO S.

Anyone install these?

I have seen some pictures of KWs and the drop is a bit more than I am looking for, even at its highest setting.

Hi there,

Thought i'd give a quick review on the Bilstein Evo S.

I'm driving a 320i/ B48 on stock suspension (non M-sport) and recently swapped to the Evo S 2 weeks ago.

The ride is now quite firm but pliant at high speeds. At low speeds the ride is less forgiving (you can feel every bump on the road) and the car has hit the bump stops when hitting sharp bumps or potholes (its a very jarring jolt through the cabin - now i avoid potholes like the plague) - the ride height has been adjusted to the highest setting but this hasnt stopped the bottoming out.

As a next step, i'm looking to change to m-sport bump stops, to give the dampers more travel and hopefully this will reduce instances of bottoming out.

Overall i would say this setup is a lot less forgiving than the B12 prokit which i had on my previous F20 BMW.

Thanks for the feedback. Maybe the Dinan bumpstops will work? I have them on my car with the springs and it definitely allows for full suspension travel and the beefier bump stops absorbs the impact much better than the stock version. I have the M Sport suspension and the ride quality definitely improved.

Thanks for the suggestion, I’ll keep the Dinan bump stops in mind. You’re on the Dinan lowering springs + bump stops combination?

I’ll probably try for the Dinans if the ride doesn’t improve with the msport bump stops. I hope Dinan ships to where I live (in Singapore)

Yup, I'm on their springs and bump stops and the bump stops definitely made an improvement.

Do you happen to have photos of both sets of bump stops?

Unfortunately I don't as they're installed on the car but I can confirm that the pictures on Dinan's website is accurate.

Ah ok thanks. I wanted to know if dinan’s bump stops are significantly shorter than the msport ones

I wouldn't say significantly shorter but enough to allow full suspension travel.

[definitelydan]

I've swapped the stock bump stops with the msport bump stops. There's about 1.5 cm difference in the length of the bump stops (see pic).

Also from the pic you can see that the strut has hit the bump stops several times (blackish top) - the stock bump stops were practically new when fitting the bilsteins. hopefully this resolves the bottoming out issue.

Unfortunately I’m still experiencing bottoming out with the m sport bump stops. I might consider trimming the bump stops as a last resort ..

still waiting for bilstein to get back on your issue. hope they solve it

Thanks for sharing. Must be the spring rate on these EVO S kit, did you feel the firm ride mostly from rear dampers? Not sure if you have adaptive or passive suspension on your G20 from stock? How would they compare?

Thanks for this. I've been considering this for my G20 but it seems like my hunt is on again. Wonder why cant they just make B8s for G20.
Eibach springs and B8s have been perfect for my F30.

Hi all,

Some updates since i've had this set of Bilstein Evo S coilovers installed for several months.

The initial months were crazy/impossible to drive as the car kept bottoming out, no matter how much we shortened the bump stops.

I had gone to the workshop at least 6-7 times to adjust the ride height settings on the coilovers, with the hope of solving the issue, and also trying different bump stops.

I'm happy to say that the bottoming out issues have been resolved.

My workshop even arranged for a complete return of these coils, to be exchanged with a new set. The new set is a lot more pliant, without the bumpiness over small road imperfections thats the previous set had. These are still harsher, than say a b12 prokit, but i can live with these.

I also notice that the included instructions/ride height settings were slightly different. My guess is that the earlier batch may have had issues.

The trick to this set of coilovers is setting the ride height at the lowest/near lowest setting (based on my layman understanding, this gives the springs the least amount of pre-load, at the expense of shock travel), paired with the msport bump stops.

At the higher height settings, the shocks bottom out way too easily, even over modest road imperfections.

For those who are interested, at the lowest setting, the wheels are more or less flush with the fender - i'm on the sport kit and i have about 5.5" of clearance up front, so that's still plenty (in my books).

Hope this helps.

How does it make sense that they bottom out when you are higher? Do you have that backwards?

i use 'bottom out' loosely - broadly i mean the shocks rebound in a very stiff manner, resulting in a very loud 'bang' that can be heard/felt in the cabin. This could be either due to the shocks 'bottoming out' aka hitting the bump stops (no more travel) or a very stiff rebound.

The EVO S coilovers are partially threaded (as opposed to fully threaded), so setting the ride height higher increases the preload on the springs - resulting in a very harsh ride.

Thanks for sharing definitelydan . I am on msport without adaptive suspension and while I like the firm ride, my wife have been constantly harping on how uncomfortable it is compared to my previous ride.

was considering the evo s for a replacement but now i am having second thoughts. hmm
I definitely do not want to go lower than the current height.

Yes you would have to go quite low for the EVO S in order for the coilovers to be pliant - else they will be very crashy.

Fingers crossed i havent any scrapes or cracked front lips yet..

[mixmastermo]

Sooo I was thinking about dropping my car a bit to get better handling and wheelgap. After reading this thread, I am not sure I want to any more.

Brother do you know the serial number for the new evo s kit you got ? Im hopping on the adventure of getting evo s kits and i dont want to make the same mistake although im on m sport suspension
