Hello readers,

i own a r32 gtr. I need to replace my castor rods due to wear.

I have the option to replace them with standard

OR

replace them with aftermarket ones - adjustable.

I drive to work in my gtr, i don't drift (im under the assumption that adjustable castor rods are for drifting). I use my car to make an appearance, i like simple smooth driving.

What i need to know,

1. Will adjustable castor rods make my driving to work a nightmare?

2. Will it be rough on the roads?

3. What is the downside to adjustables?

Some feedback on this would be great.

Thanks.

What i need to know,

1. Will adjustable castor rods make my driving to work a nightmare? No.

2. Will it be rough on the roads? No - you won't even notice them.

3. What is the downside to adjustables? They cost money and the rose joints can suffer from wear.

Some feedback on this would be great.

If you just want them for bling quotient probably best not to bother as no one other than the bloke who does the wheel alignment will ever notice them.

Thanks.

well the downsides if you use the adjustable rods with rose joints are:

1. they will be a little harsher as there is no longer a rubber bush

2. they will need to be checked periodically to make sure the adjustment part hasnt slipped/worked loose

3. they will eventually wear out (much faster than a bush).

4. if you wind in a lot of caster the steering will be heavier.

5. they cost more than getting (second hand) standard replacements

6. they are illegal on a road registered car.

They do have advantages though:

1. sharper turn in

2. steering wheel self centres much more quickly/aggressively

3. you can adjust the caster to however you like it.

If you are happy with the handling now then i would just replace them with stockies. If you would like some more adjustment, then go for the adjustables.

BTW, if you do need a set of stock rods i have a pair in my garage that i would gladly exchange for some cash.

Hi, firstly caster (radius) rods don't usually wear, the bushes (at the front) wear but not the radius rods themselves. My suggestion would be to replace the worn out, standard, rubber, radius rod bushes with nw, adjustable, polyurethane bushes. For around $100, plus a bit of pressing anda a whel alignment, they are a legal way of achieving caster adjustment.

Thanks dudes. I appreciate your help on this matter. I'm more swinging to just replacing the castor rods bushes with the neo-prene ones at Fulcrum. I suppose with all that wear and troubles there are for adjustables, it would be un-economical.

Thanks again champs.

I actually went to inquire about the same problem and was told no point gettin the adjustable rods.. But the adjustable bushes with a minor mod, where it adjusts it self, when you turn the wheel..

all up plus wheel alignment-$300... is that expensive or gd price?

Some time ago now I installed polyurethane castor rod bushes from Pedders for ~$260 installed. These were offset to increase castor 1.5 degrees either side.

I then replaced the bushes with adjustable rods, so I could dial in more castor and have it infinitely adjustable, should the car bump any gutters etc. These cost $250 in a group buy from UAS and if anything were more comfortable than the poly bushes. This is one of the best handling mods I have done.

With a 0.75 deg increase in castor, can you really notice the difference?

Whilteline only quote 0.75 degree increase with their bushes.. seems almost nothing??

That's compared to the static reading from new and a conservative one at that. Most cars have distorted standard bushes and have lost some caster over time. I have seen a 1.5 degree increase in caster many times.

Then there is the dynamic caster, the polyurethane bushes distort a lot less when the car is on the move than the silicone filled standard rubber bushes.

Bottom line, the difference is very noticeable.

:biggrin: cheers :biggrin:

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
