I need the opinion of someone with good chassis and suspension knowledge (SK? :rofl: ) to lend a hand with an issue I have.

The car is an R33 GTST which already had Teins installed when I got it. They are set reasonably low and I have tried raising them but couldn't get them to budge, even with the proper C spanners.

Due to the height of the car, the negative camber on the rear was pretty shocking, so I have installed a set of "JIC style" camber arms.

I also had to replace a rear wheel bearing on the driver side, so did that while I was at it and then went to Bob Jane and had a wheel alignment done.

I noticed when I got home after the wheel alignment that the LHR wheel sits out further than the RHR wheel (the one where I replaced the wheel bearing).

I have attached 3 pictures, 1 down the left side, 1 down the right side and a scan of the wheel alignment printout. Can someone knowledgable have a look at them and see if anything glaringly obvious is wrong.

My main concern is that the chassis is bent, but I always expect the worst.

My other thoughts are:

1. the new wheel bearing is narrower than the original, or

2: maybe I should have bought the traction rods that are "supposed" to be used with the camber arms. Perhaps they have a bearing on how far out the wheel sits.

Hopefully someone can offer an informed opinion and clear this up.

Thanks

It's got 1 degree negative camber on the LHS and 0.5 degrees negative on the RHS. What sort of suspension shop did you get to align it and then they left it that far out? Shoot the front (2 and 1.3) is just as bad.

Take it back and get them to do it properly :rofl:;)

PS; spray some RP7 on the threads and get those adjusters working. You might have ot remove them and stick them in the vice to get them to shift initially. Once you have them loose, work them up and down a few times, keep spraying the RP7. Then once a month respray them with RP7.

PPS; Actually they're Teins, throw them in the bin and get something decent. :D:D:D

OK, so the people at Bob Jane need to be shot.

What about the left hand wheel sitting further out than the right?

Get them to check the sub frame alignment at the same time.

Bob Jane :lol: :lol: :lol: :lol: :lol:

Take it to a decent suspension shop .............please................

Where abouts do you live, and I might be able to recommend someone who is worthwhile. :(

Yeah I agree with SK. Those after alignment specs are pretty darn worrying. And why did they insist on positive toe on front and back? Haha I bet the car probably doesnt wanna drive too straight.

I'd probably shoot for about -1mm total toe in on the rear, and neutral toe on the front.

Te car is actually handling a lot better than it used to, so it must have had some pretty shocking alignment settings previously.

My main concern is the rear wheels not sitting symmetrically with the body, as seen in the photos.

At the moment, when I take a fast right hander and load up the left side of the car, when I hit a dip in the road, the rear left tyre is scrubbing on the wheel arch and chewing out the tyre.

I haven't had time to get the subframe alignment checked yet but hopefully when I do, that will sort the problem.

      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.
