Daily low e46 - Bc racing

Dani · 12-19-2011, 04:55 PM

Hi !

I am looking to swap out my stock m suspension on my 320d to get lower.

I am thinking of going with the bc racing br series. This come with 7 kg / 8 kg springrates.

I use the car for daily driving and thinking of slamming it on 19" evo m3 wheels. What springrates would be preferd.

How much stiffer is this setup compared to my stock m-tech springs? Read in another thread that 9k/10k springrates is the way to go.

If you're planning on slamming it, then I would say that 9/10k rates are too soft.

X2 I'd go with a higher spring rate & have them revalve the dampner..

What i understand is 9 kg/ 10 kg the maximum springrates for these coils.

So you think it would be to soft. As i posted i use the car daily and dont want it to be bone shattering of couse.

Then the springs that come as std is super soft? 7kg/8kg ?

I would highly advise to go with 14/16. Its actually VERY comfortable for dd.

The ride with those rates would be awful with the valving of the BCs though.

OP 9k/10k should be fine for what you want, that's what I had when I had my BCs and the ride was awesome, and I never had an issue.

Picture of my car for reference.

Dani · 12-21-2011, 03:52 AM

9 kg in the front 10 kg in the rear. And it was also br series?

I take it as you have personal experience riding in the car with those rates on BC coilovers?
Btw, I dont think ff valving is that much different.

9/10 will be very comfortable. Just wont be able to put the car on the floor.

Dani · 12-22-2011, 01:42 AM

Iam looking for putting in like the green one , having it as a daily. If 9kg /10 kg soft then 7/8 would be very soft how is that possible ?

Dani · 12-22-2011, 05:48 AM

What other cooils , would be better if i want stiffer ride? In the same price? ksport, d2 ??

by ff do you mean function and form?

I have the function and form type 2's (similar to the BC's) they came with 8k/10k originally, but I swapped the og springs out for some shorter/stiffer ones. now i'm running 10k/11k. very comfortable even with the dampening close to full stiff in the front and full stiff in the back

Your E46 was on 14/16?!

Ollie · 12-22-2011, 12:52 PM

Nah he was on BCs w/ 9/10kg

9/10 will be fine to get it sitting like that green one. 14/16 if you want to go crazyy low.

I was trying to figure out how did Kelly came up with conclusion that 14/16 on BC will ride terrible compared to stiffer rates ff. Thats all.

Contrary to popular belief, adjusting the knobs on coilovers isn't supposed to change their stiffness. The knobs are there to give you adjustment for different spring rates, essentially. If you're running a stiff spring, crank those knobs to stiff. Soft spring? Spin knobs back to soft. This will help get the valving to match your springs.

Kielan · 12-22-2011, 03:07 PM

I understand that. But there is a top end to every coilover, and I personally feel that anything over like 11/12 on those coils would start to ride like dookie. The 9/10 combo I had rode just fine, and I could have gone plenty lower, but I liked how my fitment was.

9/10 is just fine to get as low as Alec's car.

I drove 20/18 BC set up and it rode like dream.

What did you set your nobs on on the 30 diffrent settings to get it to ride nice?
