Stock Springs and bilstien B8

Anyone know a good combo to use with the B8's or if the stock springs work.

The 3 has swifts and b8's currently and the ass end does not settle over bumps properly. I would just go to stock springs, but not sure if they will work properly with the B8.

 

It's fine in my 2010. The ass is still a little unsettled sometimes over a bump though

 

deal with it you ninny

 

Yea that's my issue, the ass is always bouncing over bumps, at highway speeds its not as bad, but around town, especially with road conditions currently on certain roads i drive regularly the back never settles properly and just bounces all the time.

i found some other post where the Cobb Eibach springs where a good match, but not sure. Probably try and find something close to stock spring rates. If MSM coil overs where still available i would just get those down the road, but the 6 needs suspension before the 3.

 

I wouldn't say it's all the time or even something to be concerned about. The way you are describing it make it seem much worse than what I experience.

Mine is more the slop in the rear suspension has a weird transition as it loads up

 

Too much rebound and not enough compression resistance?

 

I would imagine my best bet is to find lowering springs closest to the stock spring rates.

The 3 is much stiffer from the factory than the 6, and the internal bump stops in the bilstiens should still keep body roll down.
This car is just the DD so it does not need to be crazy, that is what the 6 is for.

 

I feel that the shocks arent the problem and they they are actually spec'd pretty well for the stock springs. I could see stiffer springs in the rear being better. I should also disclaim that i have stock springs all around, the front struts are original with ~105 k miles on them and the rear shocks are b-8s with about 40k miles on them. so i have unmatched suspension to start with. the front actually feels normal other than the miles starting to show on the damping.


when i load up the suspension on a long sweeping highway ramp there is a point as i am building speed that you can feel the back end shift around and then settle in a slightly different attitude. i attribute it to the soft bushings in the multilink rear suspension. it could be some play in the smaller stamped steel arms as well.

 

So your not having any issues with the shorter shock body of the B8 with stock springs?

I am running on the assumption that most replacement shocks and struts are likely designed with stockish spring rates in mind. Hence my thinking of finding lowering springs with close to stock spring rates should correct the issue.

 

Can you describe what you are experiencing more?

 

I will try, Essentially say i go over a bump. The front goes up and settles immediately, the rear goes up, and instead of settleing it bounces up again before it settings flat again.

if you ever follow your local ricer around town, or a car with blown shocks its similar, you can see the ass end just going up and down, never just going up and stopping.

Does that make sense? My theory is the spring is to stiff for for the shock, but there are drag bags in the rear, that I am unsure what they are inflated to, so when I get home tonight im going to let all the air out of them and see if that helps.

 

Sounds line too much spring

 

The bushings in our rear suspension do not allow for a lot of slop. At least nowhere near as much as our front control arm bushings. However...

What alignment are you running on the rear? Also have you tried driving the rear up on ramps, loosening and then retorquing all the bushings in the rear while under load?

 

My shit was assembled in Hiroshima ten years ago I have no idea what they did.
