bumpstops

[beefcream]

hey all.. my vn is almost on the stops constantly and after redoing the rear end its goin well but i find the car bounces off the stops and is rather annoyin..its running compressed ultra lows. can u get shorter stops or chop them?

[Wombat]

....I don't even know where to start with this one....


Basically, if your car is that low that the bump stops require modification, then you are in danger, in more ways than one...first, it is illegal...that doesn;t worry some people. Secondly, you have obviously altered the geometry of your car so far away from what the manufacturer designed that it will handle in unpredictable and interesting ways when confronted with ordinary things normal cars take in stride, such as mid-corner potholes and suddenly changing road surfaces.
There are sound engineering reasons why the killjoy road authorities won't let you do this sort of thing...and it isn't purely to spoil your cool looks...it's to save your life...and the other people who drive around you.

Sorry, but them's the facts...

[beefcream]

yea i know all that... i will probally go bagged eventually but id does handle well. ive done the whole back bushes all arms replaced with nolathane replacment arms and all bushes, adj panhard rod etc.

its not sitting stupid low ive heard of worse just want to see if there are replacment stops that ar just a tad shorter. although i guess it wouldnt make a massive difference since the shocks arnt working correctly.

[Astranomical]

As Wombat said - the bump stops are there for a very good reason, if your car is constantly hitting them, your suspension's probably too low.

Also, you'll want to replace your shocks...it sounds like you need to take your car to a good suspension place and get them to have a look at it, your suspension is one of the most important parts of your vehicle, if its not working properly, chances are you are driving an unsafe vehicle.

I'm sorry, but I can't see how it is that all these people seem to be happy to spend plenty of money on big stereos or engine upgrades, but don't think about the more important parts of their car, such as brakes and suspension.

hey i know it is wrong but i have had to use whipper snipper cord to hold 1 of our rear bump stops on lol but when we went to a mechanic to get a price for a new one they wanted to charge us about $70 for a new 1 and they said if u want u can jus cut the other 1 to even them out, or order shorter 1's but the way he was talking it sounded like he cuts them alot

[UNKNOWN]

Cut em in half...
Im going to find my flame suit now coz every time I say cut something I get yelled at!!!

[starfire vc]

yer the ones in my vc were choped. it had cut springs in it and sat filthy low...pretty much on the stops we just cut em in half.

[r_i_d_a_h]

i hear pedders sell them..not too sure on the price, but they are like 5mm, pretty much the same as cutting the factory ones in half

[beefcream]

mmh finally some real answeres.. ive rang pedders and they say they do no do them but im sure their on their website under rear suspesion parts. i will quote the part number and see what they say.
i think i will chop just a little of the stops and see how it rides firstly then ill do the cut in half part. im not sure weather this will be better for the ride quality eg bouncing or worse

hey mate . i think your thinkin of the upper rear spring insulators. i got em on my vl,there a thiner insulator then standard so it sits that bit lower.

but yer def's no smaller bump stop, i went to pedders chasing the same thing. they said they dont make smaller bump stops and if your cars that low any way it shudnt be on the road!!

[r_i_d_a_h]

LOL, yes yes, thats the one i was talking about.

im such a goose, i didnt know the difference between the 2 ...

ANYways...i was thinking, would it be OK to remove the passenger upper spring insulator? because the rear passenger side of my VS sits like 10mm higher than the opposite

and i really dont want to cut the springs just to level it out nor do i want to get em compressed.

[starfire vc]

make sure your meausuring it right before taking anything out..

taking an insulator out will fix the prob, but i'd be looking further and see if the spring on that side is sagged. i didnt hav any spring insulators in my vc,didnt really seem to cause much of a problem ,you can just hear the spring moving against the seat when the suspension is really working.

[r_i_d_a_h]

na na, im pretty sure the springs hasnt sagged, i got them brand new 6 months ago

and plus its a common problem amongst the vr-vs sedans to sit a lil higher on the passenger side

ill either chop the old ones in half or just remove them whole, ill see how i go.

just wanted to know if its fine to not have the inulator there, thats all

[FATMAT]

Have you priced hydraulic bump stops? A lot of comp 4x4's and rally cars use them.

[VL-187]

alot of people just chop em...
mine have been removed...

[Troyziee]

are those rubber insulator things ur talking about tha rubber things on top when u take tha rear springs out? i didnt put those back in my mates cars when i changed there springs, cbf squeezing them in, and i reakon they sit lower than myne

[beefcream]

it will sit lower without the insulator, prob shuld keep them in otherwise its metal on metal.
ill be chopping my bumpstops in half and see how we go. seems the easiest thing to do.

[r_i_d_a_h]

...but if you think about it, the front struts and springs are the same story, metal on metal.

[VH commodore]

hey peeps

i got ultralows in the vh and i left both lower and upper insulators out...lowers it about an inch which is a fair bit! the whole metal on metal doesnt matter...like the post above the fronts are like this...pretty much they are there to stop the springs falling out but if you (like i do) have shortened shocks then the springs come loose (in mine) but cannot fall out or move out of place...

im not sure about the setup on newer commodores but in vb-vl i would assume that if ultralows have been re-set lower than there may be a risk of them being able to come loose.

forgot to mention mine don't make any noises except in rare circumstances.

O and i cut my bump stops in half, but my new wider tyres hit the guards before the bump stops now...i don't see a problem in cutting the bump stops but i wouldn't go more than half...prob safer in an way actually cuz if you are just hitting them a bit than the extra inch or so of travel will stop it bouncing /effecting the handling.

waiting to get flamed but hope i helped....

[beefcream]

thanks mate, yea even with the short shocks the springs can come loose which is wat im kind of worried about due to the fact that over bumpy road it hits the stops and bounces the rear end a decent amount which is not what i want. im hoping the cutting of the stops will eliminate it hittin them all the time so its not so ****ty handling

im trying to think of a way u can secure your springs in...maybe if u can tie them using those steel cable tie things..(like zip ties but steel...dont know the name)...we did this on a vc once that had cut springs...cant think of any other way to do it.

[beefcream]

hav another question now wid these bumpstops, ive been ridin the car for a long time now wid my bumpstops cut down, roughtly 1/4 off. ther alot shorter than stock ones but my car is still ridin them constantly. i had a look with the car parked and ther still sittin on them.

does any1 know how short i can take them be4 i have the tailshaft hittin **** or any other worries???/

[Haydz]

just try it.

you can get another set of bump stops from the wreckers quite easily so give it a try. and have spares if something goes wrong.

i will be pulling my rear insulators out after reading this. thanks alot guys

lol mate your car must be super low..you got cut springs in it atm?
so currently youve chopped bout a 1/4 of the bumpstop? what bout takin out another half? see how it sits then.

[Sabbath']

Take out all the bumpstops...then cut one in half and put half in each side.
