Seeming there's some people in here who know a bit about race style suspension, what do people think of the UAS R32 front-upper arms?

Have heard magical things about them & expected them to be the first thing mentioned when I came in here...

they are a great idea. the downside is they are a tough design to make work. that is i'm not sure how much if any play will develop in them. dave loftus has used a set. I haven't used any personally myself yet so I honestly don't know. but the idea is sound.

as for the isc gear being same as other chinese stuff? no comment..... i haven't used it.

the entry level jap stuff is not so expensive these days. (most of) the cusco bits are good quality and very functional and not too expensive.

and what drj81 said about rear bushes. the only reason i didn't go that way is by the time you buy bushes for the inner and outer mounts, have them fitted, fark around adjusting them (as he said outers pretty much impossible on car with wheels on) and then find at your ride height you STILL have too much camber, you could have just bought adjustable arms (like cusco) for similar money that last well and give more adjustment. the only thing to be aware of is they do of course give more NHV vs bushes but it's never really bothered me too much.

For budget conscious times I have shortened OEM upper links and fitted good teflon spherical bearings into them.

Cut a circlip groove in the mill at both ends, machine up a spacer for the center that allows the sphericals to move still. Fit the spacer and sphericals then fit the circlips at each end to hold it together. Also needs alloy spacers on the outside.

I modify original mounting brackets by elongating the holes in the mill then welding the right size washer over the elongated hole in the new corrected position.

It's worth mentioning if ever your using sphericals or rose joints use Teflon lined ones. Just about every Jap arm has a cardboard lined spherical/ rose joint.

When you put them under load and they wear the cardboard lining gets pushed out of the joint leaving massive clearance issues.

so are those adjustable nismo arms actually nismo

cause i have a set in my shed

yeah twinkle toes. the silver ones with the black bushes and sliding adjustment be nismo. price just gone up 100%! lol.

Hi Guys,

Ollie and I ended up buying some Ikeya gear to start with - Front Upper and Lower arms, Rear Upper arm and Traction Rod. We figured this was a reasonable start and will figure out what we need to add in the not so distant future (Probably the Ikeya rear lower arms, a Cusco HICAS delete [currently just running a bar] and then figure out sway bars/bushes etc).

While we are installing the front upper arms, is it worth modifying the upper mounting brackets to "Nismo Spec" as mentioned by Risking? What are the adjustments that need to be made to do this?

Cheers

    • That's kind of what I was getting at saying you'd be here soon regarding length etc being able to add additional restriction.  My assumption (possible donkeys of you and mption) is that the length of hose to an oil cooler, and back, isn't going to be that huge of a loss. Typically you're talking about 1.5m of total length. And so far everyone in our world hasn't had issues with oil not being able to get to a cooler and back, it's more been, how the heck do we get the oil out of the head and back down to the bottom? I'd nearly hazard a guess the biggest issue people have with oil cooling and oil supply, is being able to get the heat out at the cooler itself (not enough air flow, too small of a cooler etc) Also, when people mount them wrong and make really awesome air traps so they've dramatically diminished the cooling capacity.
    • I will rebutt this and the preceding point from Dose....but without doing any calcs to demonstrate anything and without knowing that I am right or wrong. But... The flow capacity of a fluid transfer system is not limited by the smallest orifice or section of conduit in that system, unless it is drastically smaller than the rest of the system. OK, I use the word drastically perhaps with too much emphasis, but let's drill down on what I really mean. The flow capacity of the system is the result of the sum of the restrictions of the entire system. So, to make an extreme example, if you have a network with 3" pipe everywhere (and let's say a total length of only a few metres) and that 12mm ID restriction of the oil filter connection being the obvious restriction, then for any given amount of pressure available, the vast majority of all the pressure drop in the system is going to occur in the 12mm restriction. But.... increase the length of the 3" pipeline to, say 1000m, and suddenly the pipe pressure loss will likely add up to either be in the same order of magnitude, possibly even exceeding that of the 12mm restriction. Now the 12mm restriction starts to matter less. Translate this to the actual engine, actual oil cooler hose sizing, etc etc, and perhaps: The pressure loss caused by flowing through the narrow section (being the 12mm oil filter port, and perhaps any internal engine oil flow pathways associated with it) is a certain number. The pressure loss through, say, -12 hoses out to the cooler and back is negligible, but The pressure loss through -10 hoses out to the cooler, at the exact same length as the above, starts to become a decent fraction of the loss through the 12mm stuff at the filter port. Maybe even it starts to exceed it. I could actually do these calcs if I knew 1) how much oil was actually flowing in the line, 2) gave enough of a f**k to do things that I hate doing for work, voluntarily for a hypothetical discussion. Anyway - I reiterate. It's not the narrowest port that necessarily determines how much it can all flow. It is the sum. A long enough length of seemingly fat enough pipe can still cause more loss than a semmingly dominant small bore restriction.
    • To pick up what Dose is putting down. Not a lot of point running a huge hose if the motor is still restricted to the smaller size... It's only capable of flowing so much at that point...   *Waits for GTSBoy to come in and bring in the technicalities of length of pipe, and additional restriction from wall friction etc etc*
    • Hooley Dooley these things have some history! If i sell them they will need a certificate of providence to prove they have been in the hands of verified RB20 royalty! They have been stored in a plastic tub, away from sunlight and moisture. They are in mint condition. And they will stay that way, as i have sprung the money for a set of shockworks coilovers. I'm just working on getting them in at the moment, after rebushing the rear of the car, and while the subframe was out i welded in the GKtech reinforcement bracing as well.  They will get a workout at Ararat King of The Hill in November. I ran 48s on the short course there a few months ago, and i am hoping with new bushes and shocks in the rear i can launch a bit harder. There was a fair bit of axle tramp when i tried too hard off the line. a few of the corners had dips mid way which also made the car feel a bit unsettled, hopefully this will help there too.
