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.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
