Not quite.

I'm investigating this because I added swaybars and found the car has handled worse afterwards, despite having a "recipe" that seems to work for others.

My car is not dumped but it's lower than factory and after doing some reading I found that I having LCAs below parallel (and stock castor up front) may be a big part of the unbalance in the setup.

At the last track day, it burned up the outside edge of the tyres more than it ever has in a single event. The car might now be too stiff with 8/6kg springs front and rear and 27m front adjustable (max soft) and 25mm (hollow) rear swaybar.

Or it may be that the tyres are just now at the limit (they are only 235 RS-Rs) but the wear on the outside edge implies the tyres are rolling over (despite having -3 front and -1.5rear camber).

So castor and Roll centres were suggested so I'm working on that.

bcozican: How much stuff around was it to weld in the plates to create the new mount points? As I didn't think the factory mounts had anywhere that much material to work with.

not that hard really - admittedly we had a tempate to work off as other cars I know had it done first

but make a template out of card then after a rough cut out a few cuts and shaves to get it to fit properly initally but once you make one side of one side up then just use it as a template and you can bang out the other 3 pretty quickly and weld tops and bottoms together for support.

yes cutting, grinding and drilling but can be done at home if your half handy... i cant weld but mate did that bit for me

I like you are not up with the full massive techincals but my suspension / wheel aligner guy over here knows what he is on about and pointed me in this direction

ha man i did mine over 2 years ago the template we make wouldve been ditched straight away. my car in for panel and paint atm but remind me and i see what i can do about trying to make something up when it comes out in week or two

      Mistakes were made, my R34 Story

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

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

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
