front: 20mm id, 24mm od (and quoted as 192% stiffer than stock) hollow.

rear: 25.4mm id, 30mm od (and quoted as 162% stiffer than stock) also hollow.

both are not adjustable.

By my rough as guts calculations:

I have assumed they are just torsion bars. spring rate for torsion bars varies with the fourth order of diameter ie mm^4. But it is a long time since I have been to uni, so I may be forgetting something....

Anyway the numbers are:

Front

Cusco 24 od, 20 id. mm4 = 171,776

Whiteline front 22 od. mm4 = 234,256

ie Whiteline stiffer by 36%.

Rear.

Cusco 30 od 25.4 id. mm4 = 393,769.

Whiteline 24mm od. mm4 = 331,776

ie Cusco stiffer by 19%.

But that does not take into account any adjustability in the pick up points on the lever arms....

hmm, interesting. so perhaps I'll be better off keeping my rear whiteline and just setting it to 'soft'. but I am keen to get the cusco's even just for the fact they are a fair bit lighter.

old thread thats been around for years but is very useful.

I scanned it from the 2007 dealers catalogue.

salad, the cusco bars are not adjustable. but it doesn't worry me as I have so much adjustment everywhere else! one less thing to play with is almost welcome!

well back to the roll centres.

moon face have a few different options. from replacement arms with their adjuster in it (from what I can tell) to just the adjuster, down to spacers, and sleeves. costs is from around $900 down to like $200.

so dave, buy some mate, try it out, tell me what you think! lol

cheap way:

front kit (doesn't list 32 GTR though, just GTST)

not sure about the difference between the kits. I will find out though. if I get them I will just buy from japan. works out better for me that way.

I think I will give the rear spacers a go first up. See what it does. May even get to back out some rake angle again. Woo hoo.

With the spacers you don't have to press the ball joint out of the arm hence they are cheaper/easier to buy & fit.

Also I thought (Probably wrong again) that the blue spacer was the only one available for the front of the R32 GT-R.

cool. very interested to see how it goes. let's keep this thread going so hopefully we can all take a step forward. let me know what they cost too if poss. :)

Who's the aus distributor for moonface? I like the look of that stuff as i have already gone to the trouble of replacing all my rubber bushes in the suspension arms and don't want to go the next step of full adjustable arms.

Drift shop Australia. Believe the blokes name is Costa.

But as I understand it he is just starting on the Moonface gear. So an email may be the best bet. Just get in line, cause I have first dibs. :)

    • Meanwhile, 20+ years ago, I pulled out the 105mm hole saw and went straight down through the inner guard in front of the airbox to get my stormwater pipe cold air intake in. Right behind the two stock holes for the intercooler pipes. Those have no reinforcement (apart from a couple of robust pieces of steel pipe through them!). I feel that the Australian vehicle standards crews put way too much emphasis on "maintaining the crash performance" of cars and not enough consideration of "any crash is a new and wonderful experiment with a random selection of parameters and you will never be able to tell if an extra 80mm hole through some sheet metal caused a significant difference...but if you close your eyes and squint at the whole structure, engage your engineering brain and have a good think about it, you'd have to expect that it would do jack all."
    • You guys are focussing on the wrong part of this post and have headed off on an irrelevant tangent!  Clearly I'm not going to put my most prized physical possession (well it will be once I'm finished it...) on a piece of shit contraption that might fail and crush me or my car!  At no point was that even implied I was trying to buy a butchered P.O.S that some shonky clown had thrown together with a gasless MIG....  Either way I would love to see the build quality of a rotisserie that has failed.  Actually I'd love to see a photo of one that has failed full stop.  Google fails to deliver.  Never happened?? I'll either make one that won't fail or will buy one that wouldn't fail! End Post.....
    • Yeah, if you can't breathe for more than about 2 minutes, you're cooked.
    • Well, all the power should be getting dissipated across the starter motor. Therefore, ideally, the voltage drop across the earth lead should be convincingly close to zero. Certainly you'd want it to be only a volt or so at max, because otherwise that volt doesn't turn up at the starter to do what is required. A car can probably survive a bad enough earth to crank and start with only 9V or so at the starter motor, maybe even a bit less. But you're seeing only 8V at the battery terminals when cranking, so there can't even be that much available over at the starter, which simply won't do. I would have thought that you couldn't pull enough current (with a healthy starter) to make the battery drop to 8V locally. But I was ignoring the possibility that the starter is in fact crook. If it has shorted windings (or maybe the solenoid is borked and shorting to earth) then I guess it could pull a stack of current and not even look like wanting to turn over. So follow the other boys' reccos too. Because they are just as likely at this point.  
    • Depending where the whole gets drilled, and what country/state you're talking about, quite likely not.   Under ole vehicle mod rules in NSW, VSI06 allowed for drilling of holes in "non structural" areas. So you could drill a hole through the inner guard, and not need engineering. You couldn't drill over seams, and it was advised to add extra reinforcing around the hole, as well as something to protect from sharp edges.   Again, it's all about finding the documentation for where the mod is to be done, AND then being able to explain the situation, with the documentation as to why you don't need engineering, with a positive attitude, to any one of the likes eg, police, vehicle inspector, etc.
