Running no rear bar helps the rear wheels move a bit more independently, thus able to find grip better on their own.

But like many have said, it really depends on their driving style, and what they car is setup to do.

I currently don't have my front sway bar connected, but wish I did. The rear sway bar is connected (S13 HICAS bar) but I'm using stock endlinks. I need to find some other end links because they are oriented in a sort of weird way, since the rear LCAs are I think meant for an S14.

You are right in the fact that he needs caster plates, but he needs them to reduce caster after he pulls his LCA forward to keep from hitting the firewall.

Slot your lower brackets on your coilovers. This is the only way to get more leading tire on the ground besides running less caster. The first choice would be running less caster. Use your tension rod to pull your tire farther from the firewall and use caster plates to decrease your caster. It might even out. You can always slot the strut tower (I know, lots of people are against this).
TearlessJ - You did beat in the metal behind the wheel against the firewall right?

Im glad you guys are thinking in an intelligent way about dealing with caster adjustment pros and cons.
We have been in development and testing for a whole year on this.
We are about to release our new pro coilovers with caster adjustable top plates (among many other cool features) next month. I've been keeping a lid on the design but since you guys had it on your mind lately, I'll let you know its damn close to release.

you can leave the lower mounts alone if you use a wider lower control arm to get more camber.

I have a quick question that i guess is not so off topic. On my '90 S13 hatch im running all adjustable arms front and rear,also better inner and outer tie rods, Except no adjustable lower control arms(i did reinforce my stock front and rear lower control arms and using polyurethane bushings in my lowers and on my stock front knuckles) In the rear im also using Z32 rear knuckles on their stock bushings. Im using Fortune Auto coilovers with the optional swift springs. My subframe in the rear is also slightly raised using SPL aluminum subframe busshings and spacers. I dont know why but i havent purchased performance swaybars yet. Im using 17" wheels.Very basic compared to the setups you guys are running. Im just getting into the drift thing,finally,and im just trying to get on the right track with suspension(as a beginner). How low can i go safely without any binding in my suspension and without damaging anything? Its going to be street driven and hopefully i am going to enter some amateur practice sessions. Also what would you change on the car in my situation? This thread is the bomb by the way...Thanks in advance guys.

It's all driver preference man. What I like about my suspension, you may come along and go "this is complete crap" and walk away in disgust.

Ride height, especially, is definitely a driver preference thing. You may like how the car drives at a slightly higher ride height (what most Zilvians call a 4x4 ride height), or you may like how it feels better slammed.

Once you get the car to the ride height you want, then you can check for binding. Usually this is pretty obvious.

When you have your ride height set, just put the car on jack stands and take the coilovers out on the rear, then jack each wheel up till they can't go no more, and then check to see if your suspension arms and wheels are clearing everything. If so, good to go, move to the front.

In the front, take the springs off of the coilovers and bolt it back on, then jack the wheel up via the lower control arm, and see if you're hitting anything at either lock.

That's about as simple as I can make it.

Powertrix has some pretty nice solid endlinks. I'm currently running them on my car.

Pretty sure the rears would work, just judging by that picture and knowing how the S13 Sway bar attaches to a the LCA.

You need roll center correction in the front my friend. Get Dan or Martin to drop your ball joint mount on the knuckle as far as he can (I think he said he can do 4cm).

I would also imagine your steering is a bit weird from your tie rod ends being like an inch below your ball joints. The knuckle mod would fix both of your problems.

im still deciding what im going to do for knuckles next year. I think im going to run adjustable tie rod ends and lower control arms for bump steer and roll center instead of having it all done on the knuckle. still considering my options though.

Whiteline makes some with spherical rod ends. I'm not sure if it's for their sway bars, I think they'll fit stock sway bars though. Part number is KLC007

Our version of the drop spindle for the front is ready to go now.

The LCA 's are next, maybe released in march. They will certainly be different (better) than prototypes I have shown here. Right now we are making new forging dies for a new type of rod end and rod end receiver specially designed specifically for LCA duty.

The rear knuckle is the final frontier, it certainly will be full spherical.

Dan- i heard new coils will run swift springs and you guys are releasing coils for the Z33 also?
correct
All of the new pro series coilovers will come with swift springs. Z33 will only be available only in the pro version and will be released mid february along with S13, S14 and Genesis applications.

Z33 coilovers will be coil-over-damper instead of separate coil and spring in the rear.

We are also currently in development of a complete multilink solution for the Z which will have
~straight tubular rear lower control arms (instead of the OEM spring boat)
~rear traction rod
~rear toe rod

Front end of the Z33 will be
~single pivot camber adjustable FLCA with spherical shock mount and caster adjustable compression rod combo
~bolt on super angle knuckle adapter
~tie rod, tie rod end, and rack position spacer
All of the front end items will need to be purchased together since they are all designed around each other as a complete conversion front end, but the result is up to 60 degrees of angle and a super flat tire patch at full lock.

Sorry just saw this, Yea I did smash it up a good bit. Whats a recommended amount of caster with your knuckles?

Here are some pictures I just took, does the tension rod looks like its installed incorrectly? Now looking at it, it does look off to me. Wish my alignment guy would have mentioned it to me.





Heres the tire/firewall clearance at 90% lock. I can barely squeeze my finger in there. Right now its at 9.2, if I lower the caster, wouldnt it be even closer?

Amazing what a little proper setup can do to a car.

the quick answer to roll center correction? Just dont lower your car so much, and it will actually handle. But seriously though i have my control set to where they are parallel to flat ground, thinking about raising it up just a hair. Not sure where it is optimal

It's "optimal" much higher than with the arms parallel with the ground. Realistically it's a trade off between roll center and CG height, but stock FLCAs don't give you much room before things turn bad.
