i have a 1977 lx torana and have fitted a full nolathane bush kit and some people told me not to use them in the upper and lower control arms. thay say if u use them and plan on having a high powered motor that when you put the power to the ground that they pop out when the car twists. i am really confused whether or not to use them.
just woundering what you guys and girls think????

Was it based on fact that these people told you bushes pop out?

The setup I was advised on, which worked extremely well was soft neopheme on the lower arms and new stanadard rubber on the top.
Reason: when cornering the arms need to flex to allow for one side car being higher then the other (body roll) the upper arm sbeing shorter have more twisting force applied to them so you dont want them too stiff
Also boxing the arms means they are stronger but resist twiting so prone to cracking, ok in a race car because they are stripped and check regularly but on a street car where you are not likely to be checking for signs of stress not so good
this was the advice I recieved from a friend who had had Kevin Barlett help him setup his L34 / A9X. It was a genuine L34 updated to A9X

well what everyone is telling me is that if thay aint pushed in properly then thay push out, others are saying use new rubber bushes as thay can twist and flex when cornering and when accelerating quickly, and if i do use nolathane bushes that i need to put two tack welds inplace to hod them in. and see as though this is my first rebuild of a car my knowledge isnt that good im learning as im going

I reckon use anything you want in the upper arms. Whatever you think will last longer &
keep it aligned. They definately werent designed for comfort.
Why, because IMO there's hardly have enough rubber there to allow for any major flex anyway.
The bottom I would go soft urathane or the RTS rubber bushes( or what they call sports rubber bushes).
I have the hard red nolathane ones with heavy springs and they slipped out eventually so I tack welded back.
While I do remember pressing them in correctly, I cant tell if they fell out because the press fit was not tight
enough or they fell out from arm flexing.

Under normal operating conditions I have not heard of them popping out.
Main thing is to leave the bolts loose (on mainly the top bushes) till the car is at ride height, I confirm this by taking the car for a drive first, then return to tighten them without raising the front under the x-member.
FWIW I try to use rubber where i can as I have seen bolts etc wear and break before the hard bushes give.

yes you will find that most will pop out, this is more to the fact that the holes are slightly enlarged, this will happen with urethane or rubber bushes, all that is needed is 2 small tacks on each bush and that will be fine to hold them in, also if you replace with urethane the bolts for the arms can be tightened with the car in the air as urethane bushes use a push in collar so the bush and collar are seperate,. which means the bush will pivot around that, not so when using rubber bushes, these must be tightened with car at ride height

whiteline make a good POLYURETHANE bush , softer than nolathane , slightly harder than rubber , part number for the rear bushes is W61203 , most autoshops will order them in for you .

I bought all rubber bushes and crossmember mounts (except the rear leg mounts in nolathane) from Holdens and saved a fortune over nolathane stuff.
I also went with rubber as I live in Adelaide and most road surfaces are s#!t so they should give a bit more. (And the rubber has been good enough for the last 30+ years...)
Got some blue??? things in the VN which are supposed to be better than nolathane but they split and flop around. Went rubber for those too- better.

my dads good mates with a guy that is really into hill climbs hes built some pretty quick cars and hes got a ss hatch, might have to as him when he gets back from holideys and see what he thinks. and if he carnt really tell me much then i might have to put all ur ideas together ind simply trial end error them when eva i get it to the driveing stage!
