LSD and is required sooner than I thought, clutch might need to be uprated also.

ooh yeah ! adjustable camber here we come !

Genuine Cusco S13 plates for $120, even if I have to make a new top plate it is still cheaper than buying a $250 universal kit which needs cut down & still cheaper than buying a brand new chin ease set for $200

they do however need new bearings but chances are my front Koni's are a different OD so it simply means I can spec up a better bearing size and hopefully not require any horrible spacers or shims :D !

One of the studs needs re positioned OR my strut tower needs a hole slotted,

I am unsure as to which option I will choose.

have any of you guys had any CERT issues with new holes being drilled in the strut tower ? I could just weld the old hole in and drill the new hole and it would look exactly factory and line up perfectly

Further Investigation shows the bearing design on these camber plates is a bit average, just a ball sitting in a groove.

As my plates are second hand the bearings were slogged out and looking sad, so I will have the bearing section put in the 3 jaw lathe and bored out to accept one of these, stronger bearings, sealed design ( not open like the original ) and these have a special groove for the grease to sit in so it is always lubricated.

The other side of the rear camber mod is going well, just replicating all the bits I have already done Polyurethane sub frame bushings have been ordered and sub frame should be welded sometime in the next 2 weeks.

Feels good to be doing the fun mods, next I think is the LSD and a 3.9 ratio diff ( currently 3.7 ) so that will give me a bit more acceleration and only bring the RPM at 100kmh from 2100rpm to 2500rpm ( not a big deal considering the rev limit will be raised to 7000rpm when I switch to synthetic oil )

Is that camber plate fitted on the correct angle in the last photo?
In the photo it looks to be angled, so any camber adjustment will also affect the castor.

In that photo it does look to be on an ever so slight angle, IF I had taken a picture of both strut towers and draw a line across it the difference would be very minor. A any increase in castor on a z31 helps quite a lot as it give more camber on turn in without having to run huge amounts of static camber. ( this was definitely the case on my E30 which was one the best handling cars i have driven )

In saying that every change counts but the Castor arms can be shimmed up or down to increase or remove caster as required so this should be alright.

Also a fair few of the USA Z31 boys run the S13 camber plates and they seem to work well.

I have considered drilling 3 new holes & rotating it around even more so that I can get Max Castor & camber correction also but this won't happen until i switch to 2.5 ID coil over springs.

Rang Wilson Brothers Bro's and the upgrade bearings i need are $28.65 + GST each

Which is pretty good considering how much better they are than what Cusco specc'd for their camber plates

In other suspension news I am hopefully going to seal the deal on some of these, to give me full damper adjustment front and & rear !

I already have a set of Koni Yellows in the front, and I am to belive that Koni Red's have slightly less aggressive damping than yellows but as they require custom valving for when I eventually change to coil over/platform springs its a non issue

My good friend in the UK has given me a set of Michelin S46 Full racing slicks. This is the car they came off

Lexus v8 E30 280hp at the wheels , 16x9's whiteline swaybars , eibach springs Koni Yellows and Ground control camber plates on the front.

it is the quickest car I have been in that cost less than $100,000 I have personally seenthis deal to TVR's M3's Evo's and GTR's at ruapuna. I have also done a lot of the suspension work on this car. this was around the same time I owned and E30. as it shares the Nissan IRS design I am transferrign a lot of my knowlage to my Nissan Z

Don't quite know how Im going to use these yet but they appear to have had very little use.

Image

In other news Suspension arms / subframe is on the floor of the workshop waiting for the rebuild treatment.

Image

I'm Still making up my mind on Diff ratio's for an LSD,

VLSD diff head ( will be getting the shimmyd up treatment )

Image

Oh the Exhaust now has a flexi bellows and is about to get a removeable flange to make it less of a nightmare to remove and refit.

Image

Image

Also I am going to attempt a DIY removal of the training arm bushes useing a hole saw , A die grinder and a hacksaw + some punches.

As you can see the diff is also looking a bit sad & leaky so that was part of the reason I'm going to throw some new seals at it & i have some mint bearings off a low KMS diff I pulled apart to put on the center section.

Image

I just need to find a way of removing the bearings without damageing them ( i think my gear puller set will be allright but I will have to see how it goes )

And you can see the custom CV axle I build some time ago anticipating this swap, I still need to do the other side.

I figured IF I am going to replace the CV boots I may as well do it once on the LSD axles.
