Hey guys, newbie here!

I'm hoping you chaps may be able to help me ref a problem I've made for myself with my 83 narrow track 944.

I've been gradually replacing suspension parts to make it handle better which consists of 30mm front a/r/b, 19m adjustable rear a/r/b, kla strut brace, polyurethane front bushes cup 1 wheels with 255 rear tyres and 225 fronts, boxster front calipers and 968 rear calipers, drilled and vented front and rear discs, lowered front springs and koni shock inserts, koni rear shocks and yesterday I replaced the last piece of the puzzle.

The rear beam.

Instead of swapping in some stiffer trsion bars I simply got hold of one form a 968 club sport.

It was only when I cam to do up the last couple of bolts I found a problem. Where the trailing arms bolt to the beam you have two bolts and one eccentric to adjust the rear camber.

The bolt holes on the 968 are further apart. I had to make up some plates so that I could bolt the two securely together which worked but now I'm left with alot of rear camber (top edge of wheels is angle inwards and the bottoms out) and I'm certain the wheels are toeing out slightly which makes for interesting handling.

I tried going thru the full 360 degrees of movement on the eccentrics to dial it out but had no luck, I've simply turned them so that they have the least amount of camber.

I'm a bit stuck as to what to do?

Is the CS supposed to have alot of rear camber?

Can you adjust the toe seperately to the camber?

Would fitting some ally trailing arms from the corresponding car fix this and if so would I still eb able to fit my cup 1 rear wheels which have a different offset to later cars?

Should I bury me head in the sand and hope it goes away?

I know I'm being cheeky seeing as this is a 924 board but being an early 944 means mine has more in common with your cars than it would later 944's.

Ta!

Gavin

ok wait a minute...did you mess around with the trailing blades?? i hope not. The later models equiped with aluminium trailing arms had different trailing blades. I bet that now you are using fat spacers for those wheels.
If you did not trash the 968 original blades..then get aluminium arms and you'll be fine. With alu arms you wont have to use spacers at all or in worst case slim spacers. And no...the wheels should be able to sit almost straight front or rear nomatter the car they came from.

hold on...did you say boxter calipers? do they fit? what about the rear...do the boxter calipers also fit on the rear ?

Hey there,

The wheels aren't spacers'd. Only the original porsche spacers are on the car which it came with, these were there when I had its original cookie cuttters on it.

Ref the brakes I bought a kit from www.porscheshop.co.uk with discs, calipers, adaptors and pads and bolts. T'was about £6 - 700 but you can buy just the adaptors for about £80 and source the rest yourself. The discs are thicker than normal 944 discs to suit.

I'm not sure though if they do a kit to fit the rears.

They do look lost behind the wheels though!

I haven't fitted my rear brakes yet, soon.

Here's some pics of the rear end.











The wheels are a bit of an anomally, they're cup 1 wheels but with an offset to suit an early car.

When I found this site I was searching for anti roll bar information.

I ordered an m030 front anti roll bar for my car only to find it was only 23mm and hollw when it came thru. I assumed all m030 bars were 30mm for the front but obviously this was not the case.

Anyways after some searching I found several threads on here relating to fitting m030 bars to early suspension cars like 924's and mine.

It looked as though there was some confusion as to wether a 30mm bar would fit or not so just to clear things up the 30mm can be fitted, I have one now!

You need the larger dia' front a/r/b bush holders and corresponding 30mm bushes.

The ends of the bar are thicker than all the other a/r/b's so its actually too thick to go into the bushes and holders bolted tot he steel arms however with some reaming of the bush and a smear of grease they will go in and voila! Nigh on ZERO body roll! With the rear 19mm bar set in the middle position you get nice neutral handling and 4 wheel drifts rather than under or oversteer.

I do however have a spare brand new 23mm hollow front bar dammit!

I have a 924 aswell so I best put it in that now eh!

Hope this info helps someone.

hi,

i think the problem you have is that you are trying to use early trailing arms with late springplates.

the quickest solution is to get hold of some alloy trailing arms. if you want to use wheels with say 55 ofset then get 87- arms. they are plentiful and i happen to have a mint pair for sale there will be a few knock-on effects to using alloy arms...later style handbrake cables and rear shocks will be required too.

i'm pretty sure you enquired about my 30mm swayaway bars i had on ebay? perhaps you bought the 968 beam complete to avoid re-indexing new bars? i think you will have to do this in any case as the 968 is considerably heavier and the bars will be installed/indexed accordingly.

anyway, keep up the good work, lots of us here have carried out and experienced the same mods so you should'nt have too many problems in completing your upgrades.

i just looked again at your rims. 23mm offset so you need 924S or 86 944 model year alloy arms.

like i said, i think you will need to re-index those 968 bars, in which case simply re-use the old springplates and steel arms.

What I told you in answering PM:you need to use spring plates that match with arms. Not mixmatch them.

And why don't you swap in rear alloy arms also? Then you need no spacers whatsoever.

I'm beginning to wish I hadn't gone this route.

i might just put the original back in and reindex it, job done then.

I was hoping the koni's I have would fit but now the list is growing.

Arms, shocks, poss wheels, handbrake cables, will my brakes swap over???

Lets cast a vote, put old beam back in or continue down this route?

Hi yes that was me! Wish I bought them now! the car site about the same height as a CS if pictures of CS's that i've seen are accurate. Either way its alot lower now than it was.

Would it be safe place to start if I were to just put the original beams spring plate on the 968 beam in the same spline position do you think?

when I come to pull the spring plate off how do I make it not pull the torsion bar out with it?
