Hey guys, couldn't find anything else really answering this question.

Just bought a front strut bar for my r33 skyline. I've heard a few things regarding the installation, and I have a few questions and concerns.

Firstly I was told to install, I should jack the car up and have the front in the air. My question for that is, if undo the bolts to hold the strut bar on, won't my suspension come out?

Secondly I was told the struts need to be sitting as close to 90 degrees as possible, how am I meant to even check or insure this? I would have thought having the car on the ground would have kept them closer to the right place?

Thirdly, some say it will and some say it won't affect my wheel alignment (mostly camber I presume). I really didn't want to fork out for another wheel alignment... But will do what must if it is required.

Advice, info, tips? Thanks.

I can't see how the hell it would affect wheel alignment, I'd say that's a myth...

I'd recommend jacking the car up enough that the wheels are just touching the ground, but not putting any weight on the suspension - this way they don't fall out so to speak when you undo the nuts holding your struts in, but they're also not going to move about at all.

Lol,

I'm pretty confident that all suspension bits should be tightened while the car is sitting on it's own weight. Nothing should be loaded except due to gravity, unless you want it to be.

You should not notice any changes in alignment.

And, if you do fit the brace when the car is sitting on the road, wheel alignment will not change.

Yeah I think I'll do it with the car sitting flat on the ground, as if do it lifted it is more likely to create some degree of change, or possibly put un-necessary pressure?

At least this way I know it is set to how the car normally sits.

Next time I do get a balance and alignment done, I can ask them to check the settings of the strut bar and if necessary tighten it a bit when they have the car lifted, and then do all the alignment.

It would have only been the camber that changed.. But was told should lift the front to take any strain off the suspension for when doing the job. I'll give it a go when can once pick up the strut bar - hopefully this arvo.

as eiji and nathan said, its ment to be done with the the car on the ground.

Just remove the strut nuts, adjust the bar till it just slips over the top and then do the nuts back up.

you wont need an alignment and you be suprised wiht the difference in the front (at least i was, but thats in a bendy 31)

Pedders where I got my whiteline bar from still insist it won't work unless I lift the front properly. So that all the stress and pressures are off the body, and to attach it and tighten it up properly before lowering the car back to the ground...

Lol @ Pedders!

Just undo the 4 nuts, stick strut bar on and do it up!

To be honest a strut bar does sweet fa on a skyline, you are better off with a caster rod brace imo.

Ive done track days both with an without the strut brace on the same suspension and didn't notice any difference.

Strut bar - To preload or not to preload that is the questionSo. I had the oppertunity to drive my car without preloading and then preloading the strut bar. Story goes was trying to install my strut bar in my driveway with only basic hand tools and my cars own floor jack. jacked up one side and put my hand under the fender and slipped the bolts in and tightend them from the top. I can say after going for a test drive it made a real big difference.

After driving for awile i put the car on a lift today and then took off one end of the strut bar and it was dificult to pull off. Once off it wouldnt go back in easily being it was under tension while being installed. But not the kind you would want. I could actually turn one of the ends maybe 4 full turns. Reinserted it back and tightend the nuts up. Now the bar is under a slight tension. Put the car back down and went for a spin. All i can say is wow. I couldnt belive that it owuld make that much difference.

If you dont have acess to a rack easy way is just jack up the front of the car to relive the load off the strut towers when you install the strut bar. It is worth the extra effort.

It makes some sense, but I just keep getting advice both ways from people and places.

I would think that lifting the car, letting the struts hang and then fitting the strut bar would cause the brace to undergo compression when it is returned to road height.

From my understanding the strut brace was to prevent the tops from spreading apart.

As Eiji said its to stop the struts moving, so fit it when the car is on the ground stationary and they will be joined in that position.

If you lift it up and do it, putting the strut bar under compression, wont it be encouraged to lose its compression going over bumps?

Therefore moving the strut towers??????

It makes a lot of sense to do it flat. Esp the if do it up, it gets some pressure on it, helping it move wrongly when go over bumps rather than keep it in the place of when the far is flat.

I'll keep looking for info, but I put it on with the car flat for now, but may need to check it again, as the ground was a little slopey on my drive so it might not be 100% right.

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
