Sway Bars And Strut Braces


Recommended Posts

Hey guys i have and r33 gtst. I was looking to get front and rear sway bars. I already have both which im presuming are stock and was wondering if the whiteline was the way to go? I was also told to try a gtr bar which would work for the back and not the front. I was curious of if changing them would make much of a difference or should i just get both front and rear strut braces to stiffen up the body?

All help and experiences would be greatful.

Cheers guys

plenty of threads on this

in short, yes sways make a difference, they decrease body roll. 32 gtr rear sways bolt upto 32 gtst's not sure if its the same for 33's

whiteline are decent, most of their sways are adjustable, cusco ones are also somthin to have a look at, its what im running and they made a great difference

where did you get the cosco ones and roughly how much? So you noticed a fair amount in body roll reduction by changing out the stock ones? Do you also have strut braces?

Thanks mate

got the cusco's off a sau member front n rear for 350 (used), i got lucky though as they go for roughly 300 each new

as above I noticed a big difference, less body roll/stiffer feel....I also have cusco front n rear strut braces which are a cheap handling upgrade which I did first

Important note, front strut braces don't do anywhere near as much on Skylines as they do on cars that actually have struts. They do stiffen the front end up a little, which is desirable and helpful, but the main aim of strut braces is to stop the strut towers from moving around relative to each other (or the lower suspension pickup points) and so affecting overall suspension geometry. But because the tops of Skyline suspension units only carry the spring/shock loads, and don't actually locate the suspension geometry, it's not as important to keep them still.

It's the same with the rear braces on Skylines. Doesn't affect suspension geometry directly, just braces the chassis up a little.

It's arguable that they may only have a placebo effect.

Thanks a lot guys. I saw whiteline sway bar on ebay but they are adjustable and i dont think i really need adjustable since i doubt i will ever use it as a hard out track car im trying to get it into a solid set up so that i can have fun when i go to drift days. You all pretty much confirmed what i already thought but i wanted peoples opinions that have been there and done that, I really appreciate the info.

Thanks everyone

There is (or was) a group buy on here recently for all sorts of R32/3/4 Whiteline bars. Look it up and check out what you need for the R33. I have a feeling that the R33 ones don't come with the drop links - you buy them separately.

On a 32 they pretty much go straight in unless you buy a secondhandy that someone has lost bits from. Example. Whiteline 24mm heavy adjustable rear bar for R32. Comes with new D bushes/mounts and new drop link hardware. Just rip the old one out, slip the new one in (and that plays down how much of a struggle it can be to get the fatter bar threaded in if you do it on chassis stands like I did!) and bolt up. Done. On a 33, assuming you have the links you need, it should be about the same.

If I were buying right now I'd buy the heaviest adjustable rear bar available (which is what I did when I bought mine) and an adjustable front bar to match (which is not what I did because I already had a heavy but non-adjustable front). The difference between most soft setting at the rear and most firm setting at the front (or vice versa) is usually enough to allow you tune the bars to compensate for whatever little imbalances there may be from having front and rear springs not super well matched. I'd rather spend the bit extra to get that adjustability than not spend it and then wish I had.

Oh, and given your post above - adjustable will probably suit your drifty desires more. You can stiffen the rear and soften the front to make it more tail happy for drifting, and then set it back so it is better balanced for the road.

Strut braces and adjustable shock absorbers are probably two of the most over rated after market suspension "upgrades" ever sold.

Naaah mate, I took my strut brace off and nearly rolled the car..... Lol.

I have made these changes to my series 1.5 gtst over the last year, I was running into understeer at the track when pushing it through the corners so decided that it needed stiffening up a little.

I did it in the following order and had these experiences:

- Fitted a whiteline front strut brace, slightly tighter chassis in the front but no difference to turn in etc. Felt more direct, but I have a feeling it was just the placebo effect coming on.

- Fitted a _front_ whiteline adjustable sway bar and left it on its softest setting (as per instructions) and took her for a drive. One word for you, whale. Like a whale on a seesaw.

- Fitted a _rear_ whiteline adjustable sway bar and tightened up the front sway bar. Suddenly had a very noticeable difference in handling, still a fair bit of body roll (stock suspension doesn't help here) but very predictable in corners. Next track day it felt like a completely different car, very controllable slight oversteer which kept me facing into the corner perfectly.

I ran this setup for a couple of months until at one of the track days a mate of mine rolled his R33, from which I gained a nameless rear strut brace which I installed a couple of weeks ago.

Strangely, this completely changed the feeling of the entire car. I refuse to believe that this is down to the brace, rather that it may have been the final piece in strengthening the chassis, so if I remove something else it will go back to being slightly less harsh again. I haven't been back to the track since, but on the road it feels like it's having trouble maintaining grip in the rear due to being too stiff on our rough Tasmanian roads, and has lost some predictability. I'm not sure if this is because I'm going through the corner faster, it feels faster, but is most likely due to the fact skipping around and I can't tell at normal road speeds whether there is any real speed gain. Next track day will see whether I leave the rear brace in, or take it out for some flex as the closest track down here is quite bumpy.

I was running the GB. Link; http://www.skylinesa...34-gtr-and-2wd/

If the op wants something; send me a PM. The same goes for anyone else.thumbsup.gif

With regard to the R33 links; every Whiteline kit come with everything needed to fit; even lubricating grease. There are Upgraded links that can be bought separately; which are much stronger, and a very nice improvement, but these aren't compulsory.

Cheers, Dale.

I was wondering if heavy duty link would really make that much more of a difference from the ones that come supplies with the sway bar?

The supplied links are urethane bushed at both ends which allow small amounts of compression and deflection.

The H/D links are direct mounted at both ends to the Subframe and to the Sway Bar, and they contain an OEM style ball joint at each end, which have no give at all. This means there is no delay in the reaction of the Sway Bar. You CAN feel the difference.

The best thing about them is; for all the direct action and solid mounting; there is no extra harshness or noise you would normally associate with these kind of links. They are virtually as good as a race style link but with NONE of the downsides or maintenance. You just fit them and enjoy the benefits.thumbsup.gif

    • The two diagrams are equivalent. The R32 one is just one sheet out of about 3 showing everything in the whole car all at once. And without knowing the functionality that occurs in the modules, they are both equally opaque.
    • 8v - 2.48ms 9v - 2.15ms 10v - 1.74ms 11v - 1.41ms 12v - 1.15ms 13v - 0.99ms 14v - 0.89ms 15v - 0.82ms 16v - 0.81ms I'm running these values on my RB20 Neo with 570cc Denso R35 stock jets and it's great. Also bought a set for my Legnum VR4, love these injectors!
    • Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!  
    • So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
