OK I kind of get you... so how do I get hold of re-inforcement for the shock mounts like you mentioned? Is it a simple kit or add on that you screw on or would it have to be welded on? I do plan to take the back seat and strip the back as I am slowly making this car my project track car so what ever option you can recommend I'll consider.

OR basically you recommend that I dont put coilovers (the HSD im getting) at the rear? What about new springs with higher spring rates?

If you're going to turn it into a track car then by all means go all out with true coilovers on the rear. For engineering of the mounting points I suggest researching G35 Driver as well as googling but yes it involves welding.

Also have a chat to Sydneykid on these forums, he is very knowledgeable with suspension requirements & setup.

Not to hi-jack the thread but whats a "True rear coil over set up" ?

A coilover design is where the spring coil is wound around (or "over", if you will) the damper body. It's the most common design used. The back of the FM platform doesn't use it, however. The coil spring sits next to the damper.

Some places get rid of this setup and put a coilover in to where the damper resides. The spring bucket then sits empty, or some peoples will delete that entire component and replace it with an adjustable arm:

After I get my tax return, I plan to get HSD HR coilovers with spring rates of 10kg front and 12kg rear and you guys got me worried talking about what Mosoto said:

"The rear mounting points are not designed to take the weight of the car unless you plan to reinforce the area."

If these are the HSD HR coilovers you're getting, then they're not a rear coilover. The damper and spring are kept separate. So it won't be a concern for you.

I got a set of sway bars for my birthday and plan to put them on with the coilovers. Will this help or worsen the situation?

I'm not sure how it'll affect the strength/weakness of a coilover conversion, but I'll give some other advice.

As for doing the swaybars, set them soft and work your way up. I fitted my bars first and had them set to full stiff with the stock Z33 springs, which had the car nicely balanced. After fitting my Teins (12kg all round) the car wanted to slide everywhere.

With your stiffer rear springs that effect is going to be even worse.

How do you adjust the ride height with a separate spring? I'm assuming you would have to swap springs to adjust it as per a conventional shock?

The aftermarket spring is shorter than the stock spring. The spring sits in the factory location with an adjustable spacer.

So when you adjust the height in the rear you have to adjust both the spring and the damper.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
