Hi i am not sure if this is the correct section but i need new bump stops for my bilstein shocks, are these special bilstein ones or are they the same as standard fiat bump stops?

basically where can i buy new ones?

Cheers

Hi Hubby,

I dont know if Bilstein have special bump stops but I replaced my standard stop and got them from Alternative Autos. They have most parts and prices are good.

Search for their contact number on the site.

hey collieD

can you remember how much they were?

Hubby..if you run the eibachs, you would need to shorten your bumpstops to prevent them from riding.

I got powerflex ones which are firmer but last longer than the standard fiat ones. These would need to be chopped down as well.

IIRC, £20 for the pair with strut sleeves/gaiters.

ah nice one kelv, any ideas where i can buy them from? where & how much do i need to cut off them?

Yep, kelv is spot on, you'd need to chop down an original set of bump stops by quite a bit or your nice Bilsteins will be doing very little.

I have a pair of Powerflex similar to Kelvs, if you look on the Powerflex web page they list a few different sizes, you don't need anything larger than 2" or you'll be limiting your travel.

Thanks jimbo i think these are these correct size?

old worn bump stops measured 57mm dia with 22mm hole, and 2" deep should be ok?

They look just like the ones I have

How much to cut really depends on several factors...one of it is how much your springs are sagging. The older they are, the more they sag..which means more to chop. I chopped mine quite abit.

The bumpstops I got are universal ones. For bore size, measure the shaft at the top of the shocker since you have yours off the car anyway. As for the depth, a short one is sufficient as you only need a lil bit for protection when it does bottom out. In my opinion, the one you have shown is too long and would require chopping.

its 52mm long do think its still to long at that? what would you recommend?

A spring won't sag that much over it's life, maybe only a few mm.
If I was you Hubby I would cut off one of those rings from the Powerflex bump stop to make it so you have a good amount of travel.

The Powerflex is more of a polyurathane sponge unlike the standard bump stop so it doesn't have to be half a mile long for it to work, all it needs to do is stop mechanical contact between the damper and top mount or the spring becoming coil bound.
I've never heard of either happening on a Bilstein/Eibach set up so you don't really need a big stop in there.

What the man says Hubby

cheers, will i also need to cut the rear bump stops?

Yeap but it'll probably break off in the process..so you might as well just remove it completely.

is it ok to remove the rear bump stops all together?

Are there bumpstops on front as well as back?

Hubby...Yes
addict..Yes

The bump stop on the rear lives inside the rear spring mounted at the top. They usually fall out (mot fail) or get removed (mot pass) and I've never heard of the rear end hitting the bump stop or metal to metal with it removed.

hi,
I am looking to replace my rear bumpstops.
I noted that they fell off recently when I replaced the rear dampers

The diameter is about 55mm
It has a depth of about 35mm (Hubby said it has a depth of 2 inches).
I am also not sure at all what is meant by bore size

I was reading the various threads, but I am still confused

Is this the correct link http://www.europerformance.co.uk/pages/products/product_info.mhtml?product=426618

for the size?
# Size: 54 x 57 dia (mm)
# Bore 18-22mm

Cutting them short should not be an issue, right?
The rear springs are standard, and the rear dampers are the original Boge.

Many thanks for your help
regards

They will only fit the front dampers, the rear bumpstop fits inside the spring and is located in the spring top mount by a plug.
Fiat will have the rear bumpstops and all you need to do is cut them down by a few inches.

Hi Jimbo,

many thanks for the advice..
I was thinking that they were for the rears.
I had my fronts and rear absorbers( or dampers) re-worked here locally, and they fitted the front dampers with "bumpstops" and dust-covers.

But they did not have rear bumpstops....hence the slight worry
will therefore get the original fiat coupe bumpstops (or fiat Marea as advised by the local distributor)

P.S. my dampers are now completely serviceable, using back the original casing (BOGE)
It is a twin tube design unlike the expensive Ohlins (mono-tube)
The oil used is silkolene.
They even dyno-tested each damper and the data showed a stiffer set up.
It does feel sharper without any crashing...very pleased with the results
regards

I wouldn't worry too much, lots of guys here run the rears with no bumpstops fitted. Unless you are riding seriously low, like 60mm at the rear then it will not bottom out.

Thanks JIMBO

My coupe uses stock springs all round
in 9 years it has just covered 30,000km
Seldom had passengers at the rear.
So I guess I don't have to worry too much then
It was just that moment when i saw "something FeLL off" that got me worried....very worried !!!

Cheers

Hi,
I had my bump-stops fitted today. It is not the original "spongy" orange color.
It is an after market product that appears to much better made than the original (approximately 9cm long). It is $120 for the pair, about £24
I replaced the top rubber plate (£10 a pair) above the rear springs too.

The originals were not damaged, but since I bought new ones.... a fresh pair would do no harm.

I must report that all the minor crashes that previously intruded into the cabin have now disappeared.
Very pleased with the car now
thanks Kelv, thanks JIMBO
cheers

Glad you got it sorted Saiful. Who supplied you with the parts? Price sounds very reasonable too.

The parts were supplied by a local shop that deals with Italian cars....MS Sprint (of Jalan Ipoh, Kuala lumpur )

I was told that these bumpstops are made from synthetic compound and rubber, perhaps from Thailand.

The bumpstops fit "Perfectly" in to the slot at the top part of the rear springs

There is no harshness that one would expect from "polyurethane" stuff.

The original fiat coupe bumpstops, although clearly inferior, costs 3 times more here in Malaysia

I wonder who goes about buying them.

Has anyone tried cutting them in situ..?
I reckon the rears wont be a problem but it'll be a big job dismantling the front struts again..

Cutting the fronts in-situ? Its possible but very difficult to cut it neatly.
As for the rears, it'll probably snap off before you're cutting it all the way through.

I did it successfully on the fronts (I still had OE Fiat ones on my Billies), will do the rears later.
I cut off the lowest "bulge" (of the two) and yes, it does feel a bit softer over small holes etc now. Not much but still.

Used a sharp knife and made sure it never scratched the shock piston. Then put back the rubber hose/sock over the last existing "buldge". Job done! Did'nt even have to take the wheels off..

It seems the car was actually lying on the bumpstops at the front, since it's ca 10mm lower now!

Some wheels have come off some cars completely in the past

The bumpstop is not there for fun, the suspension arm can hit the subframe and because the arm is cast iron can have one or more cracks after hitting seriously.
