Hey! I have been on H&R has kit adjustable springs and I don’t like at all how the car is riding on the highway,it’s very bunpy and has a very uncontrollable feeling when going over bumps etc,also when i am driving fast in the mountains I don’t trust the car,the steering feels loose and has a dead (numb) center zone (i already have all the cs coding).
What can i do to fix these stuff? Am i asking too much from this car?
I’m currently looking at kw v3’s, hoping to get some feedback…thank you!

It's a yes, but. Answer. In the most simple way, a coilover setup will allow the car to feel different. Due to the subjectivity in what "feels good" means to you, it's hard to say if you will like it or think that it feels better.

Practically all off the shelf coilovers will be much more stiff, so you will trade bouncy for potentially harsh or crashy. For me personally I think with kw, anything less than their club sports is a poor compromise. I also prefer inverted monotube shocks over twin tube.

Appreciate your input! Is the nitrom r1 any better than the kw v3? I sae that the materials are more for the track rather than daily driving. Would there be any problems with corrosion?

Much different. KW V3 is a street coilover, while Nitron is a Motorsport-oriented kit.

It sounds like you want more of a street-oriented kit. The V3s have stainless housings, which will withstand corrosion.

Yeah,i am a bit worried about the nitron corroding or having problems longterm, i don’t really like aftermarket parts that need maintenance. I have the opportunity to buy either kw v3 or nitron r1 at about the same price,wich one should i go for?

Since Nitron HQ is headquartered in the UK, I highly doubt rain or wet conditions are an issue for them. They have some of the worst conditions there (ie: corrosion)

If the VTF feels too harsh for your taste, the KW V3 is probably the better fit. Nitrons lean much more toward the Motorsport side of things.

Appreciate it! The vtf isn’t too harsh, the car doesn’t feel planted at all and the steering is not very precise,it’s kinda loose snd i feel that the car is almost balancing if i can say that when corning fast or going over bumps at higher speeds

I'm not at all impressed with nitron. If the choice was nitron or kw, I would choose kw.

Hey! What do you think about sway bars or monoballs?

I'll chime in. I would recommend front control arm monoballs no matter that you decide for dampers. They are must have if you want a responsive front end with good steering feedback. Millway, Bimmerworld and others sell them.

Depending on your goals, I would also consider MCS from the USA. I have them on two M cars, including 3WR's on my G80. They are super compliant on the street and incredible on track. The cost is higher but I they are top quality. They are now offering rebuild service in the NL.

If you just want a better ride, I would revert to the EDC. The HAS is only good for eliminating wheel/fender gap.

Thrust bearings/monoballs should be the first thing to upgrade. We typically go with the Millway units.

I wouldn’t bother with sway bars. The rear bar is quite a bit of labor to install for very little benefit per dollar. That money is better spent on a proper coilover setup.

Appreciate it. Are there any megatives of doing monoballs if i am in an area with bad roads? Does it affect other suspension compononents or the actual monoball taking more damage from bad roads?

No downsides at all, other than kicking yourself for not doing it sooner.

I had H&R VTF before my Nitron R3's and hated it as well. Love my setup currently and wouldn't change it

I went from KW HAS KIT to Ohlins Coilovers and regret ever messing around with the KW HAS KIT. Not that it didn't serve it's purpose, just personally enjoy the coilovers that much more.

They have not demonstrated that they know how to choose good spring rates or match them to a set of shocks, and the shock dyno curves I have seen have bad rebound: compression ratios and as a whole are too stiff.

Raise your ride height OP. Lower is not always better especially for the street. When your tires lose contact with the ground, abrupt change in ride and direction will cause you to lose traction. Coilovers are not necessarily the solution especially for the street.

With my new G80 coming in a few months I'm on the fence between

Nitros, KWw, Olins.

car wont be a daily, but also don't super stiff/uncomfortable suspension.

i like the nitros cause they come with their own camber plates.

thoughts?

There’s no one-size-fits-all answer here. It really comes down to how your M3 is driven.

If the goal is simply to lower the car and eliminate wheel gap, there’s no reason to spend $6k+ on a motorsport coilover. You won’t be using even a fraction of what that system is designed for. On the flip side, if you’re an aggressive driver or plan to see track time, a HAS setup isn’t going to cut it. There's no damping control, spring rate choices, or overall capability needed for that level of use.

We can include camber plates with any coilover package, but it is nice to have a full complete kit like Nitron. I'll shoot over a PM shortly and we'll discuss your options and get you the perfect setup.

I’m not low at all, dropped like 20mm maximum

I went from KW H.A.S. kit to KW V4 and I couldn't be happier. also did the monoballs and the car feels like a gokart.
