OEM 456 rear damper hydraulic accumulator spec

No risk of substitution in my case. The BMW accumulators I bought were identical to factory except for the mounting hole size.

 

+1 here with the BMW pieces. Mounted a few weeks ago without any issues and completely transformed the car!

I do not know the specs on the BMW unit. It's been a while, but as I recall I checked the OEM part # stamped on the unit vs. the original and they were the same.
I paid less than $150 for them, and at the time I couldn't find the originals for anywhere near $300.

 

An alternative source if Daniel ever runs out of accumulators is Delta Vee.

Ferrari 456 Hydraulic Accumulator for Load Leveling Shocks

 

An interesting question.
My thinking is the pressure in the accumulator will vary the rate/speed the self leveling system returns to its preset height.
The only way to ascertain the pressure in the system is to make a test rig as nether BMW or Ferrari will tell you the pressure.

 

hi, found this old thread..

I do not own a 456.. but curious for my own knowledge..

what is this rear hydraulic leveling system on the 456 for ? is it on all 456 variations..?
I know the 456 has the red suspension actuators.. like a 355.. but don't understand what this hydraulic system is for?
does it just function on its own.. or does it operate via the suspension/sport button in the car..?

stock with the tiny wheels the 456 ride height is crazy high. and unfortunately makes the car look completely ridiculous..
but ive seen some nicely adjusted lower, with larger wheels, which completely transforms the car..

 

The hydraulic leveling system is used to keep ride height constant with varying loads in the back seat and luggage compartment.

Doubt the 456/456M owners appreciate your ridiculous comment. Would you say that to their faces? If not, does not belong here, either.

 

thanks for the explanation.

yes i would say to a 456 owner in person, that the car needs to be lowered and put larger wheels. would they do it just because i suggested it, i dont know. that’s simply my option.

but there are plenty of 456 owners who have done so.

 

Ok, then I would most likely say that’s very childish and ruins the car in both looks and ride quality.

My car has been lowered by a PO and it has 18” 550 wheels, but I also have the original 17” wheels and IMO they look MUCH better on the car than ANY other wheels I have ever seen.

And in which universe are 17” wheels ”small”? Classic cars (Ferraris, Lambirghinis, Maseratis and Jaguars) all look best in their original 15” or sometimes 14” wheels and proper tyres.

I leave the wide rims with bling and thin rubber bands to immature teens and tuning magazines who have no sense of style nor elegance.

The 456 GT is a very classy and well performing GT car as it was designed, and that is why I’ve got one.

Cheers!

 

17” wheels in general are not small.

but fitted into the gigantic wheels wells in addition very high stock ride height of 456, they look like training wheels.

and in today’s age, does not age the 456 well.

i’m not talking about bling/flash 20” wheels. at max 19”. which i’ve seen plenty of 456 fitted with.

combined with moderate lowering of suspension, completely transforms the car.

does this look ugly? if so that’s ok, it’s your preference. likewise my preference/opinion is it completely modernizes the 456.

Hi,

No I am not saying it is ugly, I am just saying that the 456 GT looks perfect the way it was designed. There is absolutely nothing wrong with the original stance, original alloy wheels and original tire size, They are all perfect. No need to improve anything.

I am not trying to "modernize" it any more than I would "modernize" my 1972 V12 E-type (15" wheels) or my 1950 Jaguar MKV DHC (16" wheels).
They are what they are, the way they were designed and I am just enjoying all of them. (and fixing a lot of things which are problems only created by oxidization, previous owners and normal wear, not the original design.)

I loved the 456 GT the way it came out back in 1992 and I still love it. For two decades I thought I would never be able to afford one, but I guess I was lucky.

Cheers!

Just perfect!

 

This is interesting information, as BMW/Febi/SWAG/Meyle accumulators are advertised at 23 (but inconsistently on various websites). Ferrari/LF stamp 155Bar on theirs. I’m looking to craft a suitable solution with a Mercedes/Corteco part and those are also stamped 155Bar. I’m curious and confused where the 23 bar number may be coming from and if it should be ignored.

any chance these are all pressured to that much within the Nitrogen bladder (23 bar) and the 155 bar is simply what the sphere itself rated for
