Aftermarket Lca R33 Gtst

[BOZ22N]

hey all has anyone else fitted the just jap aftermarket adjustable from LCA's?

I purchased a set not through JJ and I think I may have been supplied the wrong part or maybe they are just built this way?

The arm fits the car ok but the STD caster rod will not fit and the sway bar link mount is on the wrong way...

I will post pictures later but just interested to know if others had this issue or I may have LCA's for another model

Cheers Ryan

Well Im guessing the aftermarket lca you bought is adjustable? so you can make it shorter or longer but remember since there adj is done from the bush end you effectively are pushing the sway bar and castor rod mounts out so you should try and install it and get it at the same length as the original arm and see if it fits if it still doesnt fit you make have the wrong lca. Adjustment should be done after this if you wish to push out the wheel base.

answers to the above questions below.

Well Im guessing the aftermarket lca you bought is adjustable? Yes it is, Length and RC.

so you can make it shorter or longer but remember since there adj is done from the bush end you effectively are pushing the sway bar and castor rod mounts out so you should try and install it and get it at the same length as the original arm and see if it fits if it still doesnt fit you make have the wrong lca. On R33's GTSt's the sway bar mount is on the upright not the LCA, but there is a bracket fouling on the sway bar which looks like it could be for the sway bar link on other models?

Below are some pictures explaining what i am talking about, If any one has used these or has some helpful information please let me know.

Those are S chassis lower arms which have the sway bar link through the lower control arm

You can cut the mount off.

You need to press the studs out of the radius rod and see if it's got the same hole center distance.

putting those lower control arms in it you need to use a castor rod Too if you plan to set it up properly

Also your going to need to correct the bump steer issue you will create by using those roll center "correction" spacers they supply.

They change the angle of the control arm relative to the steering arm, hence effecting bump steer.

Depending on the ride height those roll center spacers may cause the roll couple to go pear shaped, it's determined by the static front center of gravity which you'll need to know to make the decission what sized spacer to machine or use.

Same kind of geometry applies to the rear if you plan on changing those lower arms too.

I spent 2 days last week on a well known GTR rectifying issues raised by fitting arms and roll center "correctors" it went backwards real fast when some parts were fitted.

Thanks Brad I had a feeling that they were not correct but the company I purchased them off swore they were correct grrr.

O well I was going to purchase some new steer tie rods with spacers to match the lower control arm to keep them parallel once I sorted out what was doing with the LCA's.

As I don't really understand how to measure and adjust RC correctly I am now in two minds one to sell these arms unused and get some upper camber adj arms or persevere on with what I have and see how the RC adjustment goes and hope it does not make it Handel like a dog.

Mmm if anyone has used these on a track car or done a similar mod I would love to hear your feedback.

Also I am running 350 centre of wheel to bottom of the guard with STD guards.

Its not that there not correct but all aftermarket LCA make one common one for skyline and s-chasis so thats why it ended up like that.
