Wheel alignment

I've searched and found some info but nothing overly comprehensive. 

I have attached the specs for alignment for a v36 coupe from the service manual of a G37 (assume they are the same). I've got an SP coupe  but assume it doesn't matter if it's a sport or not.

From my understanding caster is adjustable front and rear. Alignment same. But camber is only adjustable in the rear which is only minor adjustments. No camber  adjustment in the front on stock suspension.

Getting it done on the weekend (along with sway bars) so hoping this is all correct.

I'm going to aim for nominal. I understand more negative should improve cornering (within limits) but wear tyres out. 

Caster will change how much it wants to drive straight or corner. At the moment it's too sensitive to turning, especially on high speed corners.

If you're in Sydney, there's a guy I go to in Granville (Pedders) who knows his cars very well and always performs excellent alignments on my vehicles.

I'd suggest you take your car to him and tell him what you want to achieve. What he says is gospel, in my opinion.

are you planning to dive on the track?

or is this just everyday driving?

It's a daily that will eventually hit the track for the odd weekend. Was planning a track s15 but decided to buy this as a great daily instead with the odd track day. But mostly daily.

Yes I am in Sydney. I have it booked in for the sway bars (whiteline - see other thread) and full allignment at Blairs Tyres in Narellan. I have had great experience there previously on my S15. I went ot Pedders in Campbelltown and they offered great service (suspension sqeak unsolved because it was wet but they didn't charge me) but they quoted like 5 hour labour + full price for the sway bar... So decided to go where I knew. I'll give your suggestion some thought though as I know how much a bad alignment can change handling as I had this on the s15 with Bob Jane.

There's a big difference between tyre shops and suspension shops when it comes to wheel alignments. I wouldn't waste my time (and money) on any of those idiots.

That said, no one Pedders is the same as another either. That's why without knowing the folks at Campbelltown, the only Pedders I go to is in Granville and wherever he goes, I'll follow, because it's not about the shop/chain. It's about the one dude with the knowledge that I'm referring to and where he just happens to be.

I hear you. Thanks for the suggestion.

I know it wasn't your initial question but let me chime in all the same. Get yourself a set of adjustable rear camber and toe arms mate, your car will love it!

So I'm assuming you're saying the v36 likes more rear camber?

Sorry mate, should have been more in depth. The amount of camber and toe adjustment is so minimal that (especially if a car is lowered) optimum wheel alignment specs can't be achieved with the factory adjustments. If the car is even slightly lowered it will have way too much negative camber in the rear and god knows what toe settings.

Ahh makes sense. No plans to lower my car at this stage. If I do change I will factor those bits on aswell though.

Well finally getting my wheel alignment done (did the sway bars myself) with the new tyres on the weekend. 

If anyone has any feedback on their wheel alignment on the v36 then feel free to chime in. 

I've got the SP coupe. All suspension standard except for the whiteline sway bars.

      Duncan's V37.......race car?

      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

      Duncan's V37.......race car?

      By Duncan · Posted

      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.
