evening fellas

im having a crack at making a pair of length adjustable lower control arms for the front, and im wondering if anyone else has done anything similar. the design itself is pretty straightforward, however im a bit lost on where I can get rose joints, fat high tensile adjustment bolts and nuts ect. anyone (in brisbane mainly) know where i can get some, or better yet, a catalouge on these? Ive had a read of some general industrial parts supplies catalouges but they are pretty slim in this area.

these are r31/s13/r32 style lower arms

rose joints u should beable to get from a bearing shop (well i know pine river bearings in brendale sells them) as 4 hi tensile bolts try a nut and bolt shop

Just a question... why does it need to be adjustable?

We modified the lower control arms on an AE86 to achieve a higher camber angle on the front. This was made after taking the required measurements to work out the extra length needed. then cut up 2 sets of lower control arms and then welded them together with appropriate reinforcements.

why

coz its easier and u can adjust the set up to your needs

as the set ups between street, drift, and drag are all different

funny you should mention pine rivers bearings as thats where i was going to say to get them from....they supply us at work. But any bearing shop should be able to get you rose joints.

yep pine river bearings are great for import bits

they do timing belts and idler and tensioner bearings for ca18 and rb20/25/26 and there as cheap as

Easier?

i can understand the want for adjustability, but if im not mistaken the R31 has not got double wishbone suspension, so adjustment can be fine tuned via a strut top adjuster rather than a lower control arm modification.

like i said it makes the car easier to set up(esp for track work) as in qld u need to get a mod plate and a engineers report if u shortin (buy cutting and welding) any suspension conponments

your right craved r31s use mac struts and you can adjust camber though the top hat, but you cant adjust track. plus adjustability is neat, id hate to make a set of arms up and find out they are way too long or short. im keen on experimenting on what the cars liek to drive with it and with some fiddling to set it right.. plus the whole wanky drift cred yo thing

these arent going in a road car so engineering isnt really a concern.

      Mistakes were made, my R34 Story

      Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!

      I need more than help to finish my R33

      Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.

      Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.
