Well, i dunno - you're all like 'it did achieve something' without explaining what. Where-as SydneyKid has explained fairly comprehensively in this thread (and others) that the design of the R33/R34 chassis means that a rear strut brace won't improve handling that much - just improve chassis rigidity somewhat - and would be one of the last things you'd do.

So please - and I'm not trying to be nasty here - what improvements/achivements did it give your car in your opinion - and what other suspension modifications has it already got? One of the whole points of this thread (it seemed to me) would be that the OP was trying to determine whether a rear strut brace would be worth it. So your input about what improvements you've noticed (especially in relation to whatever suspension mods you already have) would be useful for them.

Without getting technical (because I'm not an engineer / mechanic), the bar just stabilized the rear through cornering, either at mid-range / high-range speeds. When the back gets loose, it's even more noticeable.

Other suspension changes:

TEIN coilovers

Standard Front Strut Brace

Cusco Rear Strut Brace

Cusco Front Tension Brace

JIC Adjustable Castor Rods

BEE*R Pineapples

HICAS Elimination Bar

It's impossible for a rear strut brace on R33/34's to "stabilized the rear through cornering". In R32/33/34's the control arms are attached to the rear subframe not the body, so sticking a strut brace between 2 parts of the body doesn't do a single thing for maintaining the rigidity of the mounting for the upper and lower control arms. So the suspension angles, camber, toe and bump steer benefit nothing from the addition. All it achieves is the linking of the top mounts of the spring and shock units, which in a double wishbone car contributes nothing to maintaining the suspension geometry.

This is especially so in an R33/34's where the parcel shelf support structure already does a good job of linking the strut tops. In R32's, where the strut tops are mounted lower, at the inner guards, and are therefore not joined by the parcel shelf, there is a slightly better argument for a rear strut brace, but even then the effect is miniscule. Unnoticeable by even the most sensitive of drivers.

I should mention that this is not the case with the front strut brace on R32/33/34's, because the front upper control arms are mounted to the body ie; the inner guards. So linking the inner guards adds noticeably to maintaining the rigidity of the mounting for the upper control arms.

Technically what your are feeling with the rear strut brace is placebo effect, you spent the money, you put something on the car that looks good, so it must work and therefore you truly believe that you can feel it. If you don't believe the facts then that's your choice. But if you want to prove to yourself that it's true then a blind test is the only method, have someone remove and replace the rear strut brace without telling you, then you try and pick it. I've done it on an R32 and even a current V8SuperCar driver couldn't get it right more than half the time, mere mortals like you and me have no chance. ;)

dont waste ur time with rear strut brace. (especially the jjr ones they r very shit it actually put my boot out of line lol)

if u want better handling get the following

coilovers

camber

caster

pineappleas

sways (these r the most important i reckon)

awesome tyres

awesome brakes and pads

and if u wanna go the extra step get a cage as well

Damn you SydneyKid! In another thread called "what fits in your boot" or some crap I admitted that I made a custom fibreglass esky to utilise the minimal space of my r33 boot, but then I bought a rear strut brace and it "clashed"

Now I read your bloody logical argument that this was a pointless addition and I'm pissed off.

Well I say, there are some things we don't wanna know. Important things!

Ignorance was bliss. Can't you just talk crap and call everybody thick based on heresay and Wikipedia-sourced info like so many others? Or admit you're trying to sell swaybars as the primary motive behind this?

I need a drink.......

Hey GUN_METAL_GTR32,

Did you end up getting this fitted? I have brought one from JJR and it is advertised as "Direct Fit" but when I bolt it up my boot lid wont close I have it the exact orientation as the pic you uploaded... Am I missing something here?

Cheers man

My R34 has the factory fitted rear strut brace and a factory fitted brace between the spare wheel well and the back of the car to stiffen it up , so I don't think it is just for marketing purposes

Now if someone could make these out of titanium, that'd save some weight!

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
