went to central day and managed a 1.6 60ft 11.3 1/4 in my 2wd saph and since and my rear wheels are pointing all directions and handles really poo, ive check all door gaps etc and they are mint had it on the ramp at work and everything is mint?

please no silly replies regarding the shell or rot and shell strength due to old age it was a brand new shell not to long ago! and bushes are near new!

this IS a suspension geometry issue!

could it not be you bushes that have collapsed under hard stress?

carnt really see you bendiing a beam from a hard launch tbh

unless you have twatted it sideways into a kerb

i did that and it put my rear beam out by 2 degrees but also took the shell

check the bushes mate

1.6 60ft

i'd be surprised if the beam itself is bent in all honesty.

Stavros

you managed a 1.6 60ft with a 2wd with a shonky geometry standard rear cossie beam?

maybe the poor thing died of shock

very good time i think i would leave it alone, lol at Stavros.

Steve.

richard youll

all the bushes are perfectly mint , polly bushed beam with axle tightening kit std rose jointed rear arms, and i run bilstien coil overs, the beam itself looks fine but when it was re shelled it was due to being slid into a tree side ways and the old beam was fit to the new shell, i replaced the beam for a good one and all was well now after last sunday the wheels are now sitting simiar to what they were when the old beam was bent but on close inspection of that you couldn't find any bend or kink so i'm thinking its bent in a similiar manor, and no its not been kerbed

p.s cheers for the comments on the 60ft

Bendy bendy!

If it's not bushes, not the shell, it can only be a bent arm/beam. I'd suspect the beam before the arm though.

Is the beam standard?!


As Daz says, probably the beam before an arm...

DazC

iTrader: (1)

Beam is almost standard Rad. It has elongated bolt holes for adjustment but they haven't moved. Not enough to put the wheel out as much as it has anyway.

Charlie Chalk

iTrader: (1)

A bent shock wouldnt affect it would it.. ?

Jim Galbally

surely there are parts far weaker than the beam that get loaded up which would have bent 1st?

I done my diff at Central Day

Fitted another one today and killed it on my first launch

I think your diff will die first.

Steve.

Stavros

if he doing 1.6 60fts im guessin he not on a stock diff

DazC

iTrader: (1)

Not really Rad. The arm should stop any movement being the shape that is it. It just swings up and down in some form of arc that makes the Cossie geometry shit when on hard acceleration.

DazC

iTrader: (1)

Correct. I think he got a little pissed off after smashing about the 7th diff and snapping the pinion shaft. Now on a Quaife..

The car was launching fucking hard on the day. It also had a breif problem with tramp on the run prior to the 11.3 while launching.

very happy for you on the 1.6 ricky,

and congrats on the 11.3 on a unmapped car

if you want i will do a 1.5 and 11 second dead for you

in your car of course

richard youll

i can only stess so much that the car was perfect before central day and has only arisen since then! the beams are so much weaker than the other items such as rear arms and shockers, thats why i was wondering if it had happened to any one else?

richard youll

cheers andy your on, gonna have to go now though heading into town tonight for some light beverage's!!!

bud-weis

sounds like your pretty sure it's the beam then?

i'd get it whipped off and checked...i think Brom has a jig he could probably check it over.

sounds like you may need a strapped version

cossie4i+

iTrader: (15)

How do you stop tramping ?

This is what mine is doing which i think is the cause of my diff failures.

Steve.

CozzyBrom

wat diff u runiing steve

cossie4i+

iTrader: (15)

2wd 7 1/2 inch diff.

Thats 2 i have killed in a week, been ok for the last 3 1/2 years with the same suspension set up.

Steve.

tabetha

There is no mention anywhere of the DIFF MOUNT ?
Try checking this as it is also forming part of the rear beam geometry.
tabetha

simonc

I would most certainly replace the diff mount with an uprated item if the diff was out, seems silly not too.

Simon.

lucasdemoley

I have no idea how to help, but for the times, theyr awsome

markk

iTrader: (2)

ricky if you have solid mounted the diff then the beam is bent, ive bent a few in the past, you can mod them around the tube to increase their strength

DazC

iTrader: (1)

Diff is on standard mount Mark. I still recon it's bent though.

markk

iTrader: (2)

i agree daz

AJC

iTrader: (6)

DazC

you think ricky is bent, or the diff?

after last night, i know the answer

DazC

iTrader: (1)

That was never in doubt!!

marco polo

hi mate

the beams do bend mate they bend/twist at the end of the beam normally

i have a strenthend beam fitted to mine to stop this works well

marco

pee vee

they bend fukkin hell. i was thinking how strong the beam looked when i saw mine off the car as well

markk

iTrader: (2)

wheni remove mine i will show you some pics

major strengthening

marco polo

iTrader: (1)

alot of the rally / club mans they strap wrap the beam and weld sections on the outer part of the beam for extra strenth

mine has had box sections welded on the outer part of the beam

where it starts to straighten

Tony Ryan

Like this !

CozzyBrom

is it standard if so its bound to break at the pod what power you running ?
as for beams bending on a rally or hitting somthing yes but road and track no they will not bed mike recently had his beam revamped so to speek i bolted his beam back into the jig after 4 yrs of road and track abuse and it all lined up perfectly even with the extra leaverge from the zoo mods on the centre of the beam it still did not twist

marco polo

iTrader: (1)

yo brom

but your beam is not standard are they , he is on about standard road beams that do twist where it bolts to the body thats where they normally go

Fair one, I did think that mind!... no harm in mentioning it though LOL


will be good to know whats the problem though
