LJ 4 door

What a really slick site this is for all the Torana drivers out there.
I have a LJ 4 door 138 with 3speed on the tree and the rear suspension needs serious updating. Had the vehicle in the same family since new in 1972, and in all that time, nothing has been done to the suspension.
What would be the best to handle it , as it has been suggested to use Air shock absorbers to raise the height ?
I would rather bring it back to as near as factory specifications or update it with a more reliable suspension. Would it be better to upgrade the front as well as the rear suspension at the same time ?
Is there any difference between an LJ GTR suspension and my vehicle ?
Any ideas please !!
Kind regards
George

I would be looking at King Springs and Bilsten or Koni shocks, depending on what money you want to spend.
What are you planning on using the car for? Daily Driver? Occasional Race car? Show car? etc.
What you want to do with it will determine the best route.
If its just a daily Munro shocks should be fine.

Thank you for your sound advice, as Munro shockies might be quickest and cheapest option.
Kind regards

I'm running King Springs 1" lower all round with Koni Adjustable Shock and a whiteline front sway bar. But i plan to use my car for some entry level motorsport stuff. Such as Winton fun day.
For a daily, King Springs with Munro would be good. Others to consider is Gabriel i think they are called (shocks).

Does the front sway bar make a big difference? Mine has a rear sway bar but I've heard having a rear and no front make the handling worse??

I posted a q a while back about the rear sway bar. To cut a long story short, Because of the geometry of the rear suspension, putting a sway bar on will actualy cause the inside rear wheel to have less traction or even come of the ground, because the sway bar causes the rear suspension to bind, so the weight is transfer diagonly opposite to the front outside tyre.
I probably have it wrong, but i am sure Greg or someonme will correct me

i know a rear swaybar didnt do much for me around qld raceway. took it off, put a front one on and starting almost lifting front wheels instead of rear ones

The XU1's had the front upper control arm mounting pivot holes drilled 1" lower than the standard LC/LJ's. The positions should already be punched , just need a redrill to that spot.
Might as well do that if going a full rebuild up front.

I had a look on my lc 4dr and cant see any signs of punch marks an inch lower.

Looking at the position of the original holes, clearance and strength i would think you could put the new holes up to an inch HIGHER not lower on the chasis.
correct me if i'm wrong.
if any of you two door people could measure from the top of the chasis rail to where the centre of the upper control arm attaches would be a great help and clear up this issue real quick.

You may have an XU1 front end already. If the holes can't go any lower - they are in the right spot. Don't mount them higher .

Personally I would do a mixture. Frotn bar hard springs with no rear bar and medium springs. this will give you teh best of both worlds. not onyl great in a straight line but also reasonable going around a corner. You will find if you hit dirt though (race/hillclimb situation) that it will become very difficult to get speed out of the car.
Think very carefully about the setup as get it right and the car will drive great. get it wrong and you will fight the car to drive it.. Talk to people in the industry. once you have spoken to most of them combine the results and you will find a good choice arise.
Cheers
PS: Bilsteins run terrific shocks and kings or whiteline are also great with them.
