Handling 101: Reduce Body Roll - ARB or shocks first?

Previous E46 325i ride has M-sport suspension and Racing Dynamics ARB ...all I can say..AWESOME...without sacrificing comfort too much...wife and kid don't complain over the long journeys along NSE.

To improve the handling of the car, the best mod to do is to change the ARB.

Changing to aftermarket absorbers will only firm up the ride, and will not reduce body roll. Replacing the springs (usually lowering it with eibach or H&R), will lower the car and the center of gravity which gives you a feeling of lesser body roll but neither these two mods will help as much as replacing the ori ARB.

Thicker/Stronger ARB will restrict the up/down movement of your wheels and also the camber change while cornering. All our cars come with negative camber, as you corner the negative camber will decrease. If the ARB is soft the camber change will happen easily (at a lower speed) and before it reaches 0 camber the tires would be screeching. That's why most stock cars are set to have a softer ARB setting at the front to have an "under steering" tendency as it is easier to bring the vehicle back into control, compared to over steer. With the ARB installed, you can feel the car can corner a lot flatter without losing much grip. It will take a lot more speed before the tire start to screech

I have had H&R on mine for 3.5 years and they work beautifully except the bushes which disintegrated within 1 year. Best is the original BMW Bushes, just some minor drilling will do. H&R ARB is not made from Aluminium but high tensile strength steel pelted with metal bearings. Its quite heavy compared to the original BMW ARB.

Go for it and your car will never drive the same again

Al ... only 1 year for the PU bush? Dang ...

 

[ALBundy]

Yeah the ori H&R bush doesnt last long, usually the front ones. Another M3 owner also had the same issue.

The bush may not cost much but removal of rear ARB is a lot of work ... wonder how much its gonna cost. I do know the original BMW rubber bush is very solid and lasts the years ... should have left my car longer and gotten them to use the ori ones ... oh well ... lesson learnt!

Now the sifu has spoken.

Anyway, given my current situation (stock Boge shocks Front - 2 years old, original BMW shocks Rear - 8-9 years old but no leaking), which would be the best option in solving the heavy roll/tilting issue during cornering AND still be able retain current ride comfort?

Option 1: NEW Boge Automatic/Bilstein B4 shocks (about RM1.1k all-in, using old springs) + H&R ARB (about RM2k)

Option 2: NEW Titan shocks (about RM2.9k all-in, using old springs)

Am leaning towards option 1 but would the car be feels odd/too stiff with the thick ARBs and yet soft shocks?

My E46 has been on titan since 2 years back. :top:

Wingzee,

Try to install the ARB first.

That itself will give a tremendous improvement in terms of reducing body roll. On mine I set it to medium and its good enough. You can feel the car can corner "flatter"

Cheers

rear arb is more work to replace on e90 than e46. dont have to remove diff on e46

Now no need to remove subframe. They lower it then slowly thread the ARB through. Hehehe

 

[Mavik]

Is it true that putting arb on d car can give more power ar? My friend friend say he put the tai sai arb and now d car can very fast zoom to 200.

I know how to make the car go faster, press the accelerator a little more

 

[anaksarawak]

A youtube to racun you my dear friend

[wingzee]

G, no good lah the video. I already thought of postponing the absorbers and ARB for now but after the video, both are back in the pipeline!

 

[swansonsz]

alamak... racun racun racun. Sunday morning sudah kena racun.

Bro wingzee, got buy 1 free 1 ARB set ka? can split the cost 50-50 haha.

We can organize group buy lah if anyone is interested. Hehe

 

[gendong]

if got group buy im in bro!!

 

[wingzee]

if got group buy im in bro!!

Bro you got M-tech absorbers and Eibach already what else you need? Haha

 

[gendong]

errr.......ARBs? hehehe.....so when you gonna initiate the group buy bro....me waiting....
