This is the roll center, suspension pickup, and steering angle modification thread.

What will be the right length to extend? 20 or 25 mm?

[Z33dori]

there is no right amount, depends on how much camber/track you wanna add

[godrifttoday]

what size rods are you guys using to weld into the stock lower control arm to be able to adjust?

I don't really want to add more camber, I got clearance issue with frame rails
My tyre rub the rail before full lock

[Z33dori]

20mm should be enough, i dont think anyone has done less that that.

[Z33dori]

my buddy just extended his last night
S13 arms , 40mm extension

[huffandpuff00]

that is equivalent to dong a 25mm extension on s14 arms, but way cheaper in the end!

[pete240]

Had he done heim joints on the inner mounts he could have gone over 40

[C. Anderson]

But that would have jacked with the mounting of the tension rods too much.

[shoguner]

So i have a question.
Mikerbike extender his by ~35mm and at full lock his trailing wheel hit the tension rod(correct me if im wrong) so he put spacers on. I want Now i know Cor Integration makes some curved tension rods. Has anyone tried to make their own yet?

[Silvi]

what tie rod + end recommended to use after extending the LCA?

Didn't change the TC rod mounts at all.

Does anyone know anything about Z32 steering racks?
They seem to go for cheap, even the HICAS ones, and they have a very nice ratio.

S13/S14 rack - 17.1:1 ratio - 3.1 turns
S13 HICAS rack - 14.9:1 ratio - 2.6 turns
Z32 TT HICAS rack - 14.8:1 ratio - 2.4 turns

I know they use an electric pump, but it would just be a matter of blocking off the electric motor, or swapping the upper housing from a 240SX rack. Other than that, everything should bolt up.
The only thing I have been able to find as to why they would not really be an upgrade is that they may have shorter travel. Can anyone confirm this to be true?

[GripTerror]

whaa? they use electric really? Thats awesome! Thats better than are slush fluid ones then!

[Matej]

Actually, the electric motor is for the HICAS system, I believe.

[Razi]

Pretty sure that Z32s have less angle than S13s though.
Not sure if that's due to the rack or the knuckle.

40mm from the crossmember mount is ALOT. Also Its better to extend on the other side of the tension rod mount (like above) to help with the wheels hitting the tension rods with high angle knuckles.

[Silvi]

Just extended my LCA by 25 mm




But now I still got 2 problems:
1) the wheel is touching the tension arm exactly at full lock.
So I thinkin to buy thoseany recommendations?)
Driftworks Geomaster Tension Rods S13 S14 S15 R32 R33 R34 Z32

2)I cut my inner and outer tie rods by 15mm because of the rack spacers and now I got zero screwing on the inner after the extension.
So im really need recommendation which inner and outer tie rods I have to buy.


Thanks!

1) How many more degrees of travel do you have before hitting the steering stop? (either LCA or rack) If it's just a degree or two, you might be able to get away with sliding on a small spacer for clearance. If not, those tension rods should help.

2) Are you saying that you cut down your tie rods and now they're too short? If so, go get another set of stock tie rods and run those...? If not, PBM's new tie rods are really sweet, I just got a set this week and they're significantly longer (and stronger) than the stock setup. Combine this with an S14 outer and you should be good to go?

[Silvi]

The rack spacer add about 20mm total of rack traveling. At full lock the tie rod hit the lca and full lock to other side the wheel hit the tension rod. So i will try an 5 mm spacer and hope it helps. If not i guess I will order DW rods.

About the tie rods, I cut them before the extension. the reason was that the rods are too long and i cant recanter the rack and avoid toe in.
Im looking for better and lowered than the stock outers, something like those:

Thanks about the PBM inners, I will order them

I'm not sure if you're arguing my point or agreeing it. Either way, what you say is correct.

Now that I've extended my control arms ~37mm, I have decided it's overkill. And if I ever extend control arms again, I'm only adding ~25mm.

S13 or S14 ones? On S13?
I guess I will go with 30mm then.

A little bit of both. I think it's fine to adjust on the inside for fine tuning but 40mm seems like a lot of stress for a stock arm at that spot.

My buddy Mestiso is running the Corr TC rods. I believe the front control arms are extended 25mm from stock S13. They are Battle Version weld in adjustable kit.
Here is a pic at Top Drift...and no he did not spin.

[oni jake]

Any video? That picture is just not doing justice to me. Things look to be fucked up to achieve good angle.

[nieko]

The ugly cars usually get the dopest angle, haha.

[Motary]

that roll center looks messed up.

Bricks make anything look presentable.

Random, but do you have any fender mods? Tubs/No Inner Fender/Whatever?

No video...Not sure what you mean by "to fucked up to achieve good angle."

Here is another shot at Sonoma...



With the Corr TC rods are limit is now the front sway. Corr now has a new front sway to allow more angle.

It isn't that random bro, that is what this thread is for! And at the time this picture was taken... no.

The only thing I had done to the front for clearance was my friend THOR. (BFH) lol. I literally sledgehammered everything that hit then spray-painted it black and did an event and wherever the paint was missing, I did more sledgehammering.

What really ended up limiting me was my tension rod/sway bar.
