Hi guys...

just a quick one, my car is in the garage and I haven't had it aligned for ages so I think its due... especially since I got air over a ripple strip as I straight lined turn one at sandown :P and its been a bit wonky ever since

its an R33GTSt running:

the SK group buy kit Bilstiens with King springs

Whiteline sway bars set on medium front and back

Azenis rt615, 225's front 255's back

I was going to go for as much neg camber at the front as possible but I only have stock adjustment so I think 1.5º will be as much as I can get? Neg camber at the back will be about 0.5º... this should be fine as is, I have the adjustable bushes in there

Wheel to guard measurements are 350mm front and 350mm back, there is probably a 5-10mm rake towards the front

as for toe, last time I had it set I think it was set toe in front and back but should I be looking at toe out at the front and toe in at the back? and by how much?

I'm not stressed at tire wear but for reference at the moment it seems to chew the middle/outsides of the fronts and the insides/middle of the rears

um what else... I have the adjustable castor bushes at the front so have about 7º there from memory

pineapples in the rear set to squat

hicas is still active (if that makes a difference)

stock vlsd struggles to put the power down out of 90º, second gear corners (sometimes it single spins in third gear too...eeew) don't know if alignment can help here but thought I would ask

geez that turned into an essay, sorry! any help is aprreciated

well there is not much you can set really, there is no standard camber adjustment on the front so you can't change that.

castor go for as much as you can out of the bushes

I would try 1mm toe out each side and see if you like it.

maybe a bit of toe in at the rear 1mm each side.

rear camber is ok, but if it were me I'd try a little bit more, maybe go to 1 or 1.5 degree neg.

unfortunately the only things you can adjust from standard is toe, and rear camber. plus you know have some castor adjustment which helps, but some camber adjustment at the front would be good.

cheers beer baron... will try the toe out at the front and see if I like it... what's the best way to get some more negative camber at the front? do the whiteline bushes allow you to go for more neg camber? they are the only part of the gb kit I didn't get as I was happy with the camber at that stage...

also would a front strut brace help? I don't have one as I was always skeptical at how much they improve handling

I'd get a strut brace, it will stiffen up the front end a touch and every little bit helps.

Front camber adjustment would also be beneficial. The whiteline bushes will let you wind a bit more in.

It's also worth thinking about swaybars followed by a diff. $200 per end for swaybars is just a bargain when you consider what a difference they will make to the handling of the car.

yeah I think if I can get close to 2º neg camber out of the whiteline bushes that will do the trick... I have swaybars already and yes I would definately recommend them

strut tower brace I'm still unsure about but I guess for around $100 it can't hurt... who makes a really thick/sturdy strut brace for r33? Cusco? Whiteline?

strut bar is much of a muchness. it's just a piece of bar. chose a brand you like the look of.

whiteline front upper control arm bushes will give you some camber adjustment, or use some replacement upper arms.

Honestly, be careful with camber. Im running 3.5deg and the trips to Phillip Island, Sandown and DECA have been enough to eat the inside shoulder. It works really well. But im going to wind it back a little as it clearly is too far towards track.

I used to have -3.5 deg usign bushes, but you need to run an adjustable inner and outer. But again, when i get some more spring into the car im going to get soem cusco castor arms and try to get about 6.5 castor and wind the camber back to about 2.5. you can get around 2.2-2.3 out of a single adjustable bush

My 33 gtst came with a front brace no rear brace and stock suspension.Ist purchase was a rear brace and i did notice a difference. It definitely tightened the back and a little. Next up came the adjustable whitleline sway bars. These things are great. even on stock springs and shocks i can dial in under/oversteer to a degree and i still havnt fully explored them yet.

Not sure where to go from here. Thinking I might do the cradle and diff bushes etc plus better control arm bushes. As to what coilovers I will end up I think the reccos by Sk will be the way to go.

Most lines I have experienced with a/m sus ride like billy carts. I dont particularly want that. If the euros can dish up a well behaved package that still delivers excellent ride quality I dont see why it cant be done on a skyline.

My old car is track only so not to sure how these setting will be in road car.

Fronts

4 deg castor

5 deg- camber Cusco upper arms

1mm toe each side

rear

1.5 -deg camber

1.5mm toe out each side lock bar in place.

struts

cusco front

cusco three way strut

cusco front tension rod ( inbetween the castor arm mounting point ).

sway bars both cusco

ohlin shocks

It quite neutral in its handling unless to heavy on the throttle at apex then will under steer a little, very pleased though.

I'm running the SK package with stock shocks/spring. Very tight feel and handles well but still a very comfortable ride.

I recommend more throttle mid corner to get those wheels spinng lol

How did you go with the sway bars?

Leave them both on medium?

My car has same set up as yours (cept whiteline springs) - I have a front strut brace and am waiting now for sy kid camber front and rear (been 6 weeks now....) so would I am interested on peoples thoughts for the sway bar settings.

apparantly mine are

front - medium

rear - hard

Oh, and Ive got the castor adjustser from the group buy also

yep left them both on medium... I have had the rear on hard before and to tell you the truth it probably handled better that way but I went faster with it on medium so I left it alone... if I put it back on hard it might help stop the diff from spinning the unloaded wheel

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      By GTSBoy · Posted

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
