Adjustable Upper Arms - Problem R32 Gtr

My R32GTR runs with coilovers (around 355mm front guard height).

I have adjustable front upper arms, and have around 1 deg neg set up.

This means that the upper arms are quite extended (to reduce the neg camber when it is lowered).

The problem is that the outers of the arms are fouling the inner guard, and actually have bent the lip of the inner guards a bit...

How does one fix this problem, without running a lot of front camber?

The pics should make it clearer...

May sound stupid, but are the in the right way?

I had this problem when I got my upper arms, turns out I put them in upside down, gave me lots of castor and not much camber. :)

Flipped the arms around and can easily run 1deg camber at 350mm ride height with no issues of fouling.

interesting... can you do me a favour and see if the fat part (i.e. the female side) is on the outside like we have on mine, or the skinny part (ie. the male side) is on the the outside of yours?

cheers Showza!

Ah bugger, mine are different to yours though, mine are a turnbuckle style arm. But would only fit in one way anyway, one end is slightly wider than the other.

Only thing I can think of is are the arms staggered the right way? As they look like ---> I they should be staggered so the upright is pulled foward as far as possible. The body end looks right, but cant really tell for the upright end. But seems a bit odd that the arms themselves would be around the wrong way...

Now you've got me worried.

I fitted adjustable bushes to my upper arms yesterday and I'm waiting to have a wheel alignment on tuesday to set my camber at neg 1 deg with 345mm ride height.

The arm looked like it might go close but I thought it would be ok because I had never heard anyone say they had a problem... until now.

Come to think of it I thought the suspension felt rock hard when I tried to bounce it.

I thought it was the new bushes being really tight but now I'm thinking I may have your problem.

Are you sure you have NEGATIVE camber. I would have expected the adjustment to be compressed to give negative, ie shortening the arms will pull the upright, and thus the top of the wheel, in towards the centre of the car.

This may sound stupid - but the stock ones are handed.

Did you put the right one on the right hand side & the left one on the left hand side?

Also what is your ride height & how much castor are you running?

Yep i checked the fitting guide and there is only one way they can fit with the adjusters on the top.

Ride height is 355ish and the castor rods are standard.

something about those arms looks odd, do they have any offset like the std arms? almost like the upper arm is swinging in the wrong area under guard...

They are offset like the standard arms, you can see that the top pic is the RHS and the second pic is the LHS. In the LHS pic you can see the offset bit in the top right of the pic

The shock mount simply holds the shock absorber - it has absolutely no bearing on camber.

Ronin - did that 1 deg neg come from a wheel alignment machine?

Yep it was done on an alignment machine. It may have slipped though if they weren't done up tight enough - It's getting towed to the workshop tomorrow so hopefully can sort it out.

Many thanks everyone for the replies, keep them coming!

I have the same adjustable arms - if mine were extended as far as yours are they would foul the guard as well. I have 1 deg neg camber but the arm is only about half way extended, and i have about 10mm clearance. IIRC my car is around 345mm hight, which should mean i need to extend the arm more, not less, so NFI whats going on with your setup... If you're in Sydney and want to check out my install, let me know.

Mine did that when I asked them to wheel align my car at -.5 deg camber. It made a knocking sound every time I hit a bump. Had to knock bit of metal straight and prime, paint exposed metal.

I triple checked that I installed them correctly.

I think They don't like anything less than -1.2deg or so depending on alignment of vehicle.

the arms are definately installed properly, and it looks like it's the upright hitting the gaurd not the arms. the only way out here is run more neg. so hardnen up boyo and run more neg.

      This car has run before on this z32 ecu can get the part number for you, I have tried with no AFM it didn’t change anything, I compression tested today 140-150 across all 6 cylinders, also set fuel pressure to 43psi. The only weird thing was cylinder 1 plug was black and fouled other 5 cylinders were just wet with fuel. Spun cas by hand and confirmed injectors are clicking

      Since you came here to ask for help, have you thought about answering our questions, that might help us lead you to why it was skipping, or have you given up on getting advice?

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...
