it may seem fine. and laser alinger may be top shelf for a truck or whatever and maybe some laser machines are better than others. this was the latest beissbarth machine. maybe 1 month old when I used it. and it doesn't take a genius to figure out where they fall down. they have those 4 massive things hanging off each wheel so the slightest movement with the car or someone farting etc sets them moving and figures bounce around. old school is best. trust me. we are talking tenths of a mil in measurement either so the amount of accuracy is crucial and those type of machines just don't have it.

I'll see if I can get you a pic of the traction rods.

there you go (it's the gold ikeya arm):

hey bb, thanks for the pic of the traction rod, though i would consider it more of a camber rod. The whiteline rear camber kit allows you to lengthen or shorten that arm.

About the laser alignment, which i use myself when i go to bridgestone, what you have posted is pretty ridiculous. I mean its not like i tighten the nuts while the numbers are changing or someones farting lol. Having done over 5 alignments my self and working progressively through alignment settings from pretty conservative to now a reasonably aggresive setting, i have no doubt in the equipment.

On the other hand i dont believe the string method to be a bad one, and might give it a shot in the future to see if there is any improvement to be had. On the other hand i pay nothing when i go to bridgestone so i might just keep doing that.

I also think the fine measurements u are talking up are not that fine, i mean say u ended up with 2.0 front neg camber RHS and 1.9 on the LHS id bet my left nut u/me whoever couldnt tell the difference.

cheers bb

lol, consider it a salami rod if you want. it's an upper control arm, or traction rod or toe control rod. the main upper control arm adjusts camber. the traction rods mainly affect toe and the angle of the upright, not camber.

as for fine measurements. 0.2mm of toe makes enough difference. think about it. 0.2 of a milimetre. laser alingment in my experience is just not reliable and repeatable. hey I was a big fan until I started doing more and more stuff with it then I realised that it just wasn't repeatable. plus it takes longer for me to set-up than string line or set-sqaure type and when under the car on the lift and your head breaks the beam that is pretty annoying. look if it's my camary or whatever sure I wouldn't have a problem using it. but for the GTR manual is best. have a look at giants experience with laser equipment.

I'm never getting lazer alingment again. the cocks can never get it right, and also cough and spit the dummy when you tell them exactly how you want it.

surely i could go to another place, but i agree with richard here, the old school way is still top notch! And just found out my dads mate used to set up john bowe's car many many moons ago,

yeah it's easy to do. as long as you know where and how to adjust your various suspension arms, and how to read you can do it. knowing what is a good setting for any given part of alingment is a different matter. it takes experience, time in the car etc to find what works, but you can usually bludge some good starting points from somone.

you want something like this basically:

i have just bought a smart tring set up out of the states, but up until now have been using curtain rods and string (cost about $30) :)

another big issuee with laser stuff is attachment to the rim, if there not careful or if your rims dont have a good lip on the rim( eg r34 rims), they fu@#k it up everytime.

the ones I posted are ikeya formula. russ's ones are smart string. google smart string alignment you'll find it.

the ikeya one is about $400 for a full set.

but you can make your own pretty cheaply with just some nice metal rulers, some tubes and some string.

bear in mind the smart string $400 is USD. and also to do camber you'll need a camber gauge another $200odd USD.

the ikeya one is a bit cheaper at about $400 delivered for the "full set". and it can do camber too.

basically you need to measure the camber at different steering angles then apply a formula. in a workshop you have the car on a degree plate. you turn the wheel 20degrees, measure, turn it 20 the other way, measure and they usually have a thing there to calculate it.

might have a read into that ikeya one. thanks bb.

suppose there's no way of doing castor?

i'm also thinking, wouldn't it be 'ideal' to have the car on axle stands while doing any sort of alignment (not in mid air, but just to re-seat the wheels on the surface)? or to at least do the alignment, roll back and forth and re-check?

Bugga to the caster i just knew it wasnt going to be as easy as that :-)

And i would think you would need the wheels with the weight of the car on them to set it up, bump steer and all that

    • 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.
