Re: James 85 Z31 300zx - Rear Subframe Camber Mod IRS

Post by 85_Z31 »

So it seems Odd I'm working on making the rear Camber Adjustable Before the front, but anyways ....lets crack on

1x IRS Nissan Semi Trailing Arm Subframe for reference

Image

Now were going to slot the holes a shitload to correct camber for lowered cars

Image

The idea is for street driving you get it set to about 1deg neg, and for track days you can take the correction out IE when you drop your car and the rear camber skyrockets to like -2.5 you can add neg camber back in up to this amount.\

another view

Image

And the start of the adjuster plates, so far they are only 4mm thick but I am going to double skin them to give them some beef as they will need to hold a fair bit of tension. I will also gussest the sides

Image

Here you get the idea that there will be a plate welded across the bottom ( 7mm flat ) with 2 holes drilled in it to match the adjuster bracket.

Its just the the chain adjustment on a motorbike.

Tomorow I need to file the bottom of extension pieces dead flat, and then I can tac weld the big plate that goes underneath that the adjuster bolts to.

I am doing all the work, however this will be tig welded by a guy who is friendly with the local Certifier 8-)

Been out and Spent HOURS hand filing the bottom of the extension pieces so that they are dead level, and also some more work on the adjustment brackets.

I found a nice big hunk of 10mm flat stock, but i might have this milled down to about 7mm as I can't see any reason for it to be that heavy.

Image

So far its going well, Tomorow I will cut the slot down and figure out the max adjustment, and then drill the bottom plate

I am nearly finished on this side, so now you guys get to see what the final thing looks like

its bad ass to actually see it coming together. there are a few kits you can buy to do the same job

but they cost heaps and I think Mine looks better.

Before anybody asks I will not be doing this for anybody even for real money, takes SOOOOOO LONG to get it right

Re: James 85 Z31 300zx Camber Mod - looking quite flash now

Post by 85_Z31 »

Been for a massive drive & tuning session around the port hills past sign of the keewee and out to diamond harbour

Probably scared a few cyclists just with the noise of it on full song along ( yes we were being responsible and not dickheads )

Had a Z32 300zx following us for a while but we lost him pretty fast

SUCH a cracking good day.

Definitely needs bump steer spacers to correct front end geometry it feels okbut the steering wheel shaking is getting a bit annoying.

Used tons of gas made tons of good noises on the hills.

SO dam happy with this car, so much power to pull up the hills and pass people, i have decided it has quite a lot of old skool brutal character with all the neat noises and clonks and pops and sounds it makes.

You might wanna spend the week finishing your suspension mods and tuning, if you plan on following (and keeping up with) a B310 :burnout: :poke:
