tein tierods

kaaz 2 way limited slip differential


hopefully it will be ready for dday for people to drive!!

[Funk]

wooo yay.

i want a lap with cast

[RoadRacer]

fanboy :lol:

how much neg camber can you run with the tein tierods?

[Matt Vassallo]

tierods of any kind don't really affect negative camber. negative camber is affected by the angle the strut is mounted at. sliding the upper mount towards the center of the car increased negative camer, sliding it out towards the outside of the car will lead towards positive


the tein tierods are a stronger unit over OE, offer more breaking resistance (they will bend instead, alowing u to still steer at least) and give additional steering angle

when's install day

[Boomer]

you know ill be there to help install w.e

[Epstein]

You know that the spacers that increase your steering angle also introduce more bumpsteer, right?

[Chin]

Or if your baller you can have adjustable FLCA and adjust camber that way allowing your camber plates on the coilover for a different use :D

[Matt Vassallo]

matt chin;

who do you think told you that, that's how my car is set up.

hopefully it will be ready for dday for people to drive!!

Is there a waiting list for driving this thing? I wanna be on it.

Charles

[Matt Vassallo]

let me drive your car then

i wont put it into anything too harsh :)

As long as you don't break it....

Charles

[piner]

whos on the list to drive it?

[ryojikaji143]

wow, cool, it is getting more and more like my car. I can't wait!

Please explain this theory.

[Epstein]

Because you're moving the inner steering pivot outwards away from the FLCA pivot.

[Matt Vassallo]

bumpsteer is an internet mechanic term, at least to the s13s it is

drive my car its lower than nuts, it has no bump steer

but red smoke comes out of it :)

[Epstein]

It's just what I hear. I haven't had a chance to take a tape measure to the underside of the car. I don't suppose that anyone here has a bumpsteer gauge?

If your tie rods and LCA's are not at the same angle,

AND/OR

your tie rods (from pivot to pivot) are not the exact same length as your LCA's (from pivot to pivot) then your car does indeed have bumpsteer.

However imperceptable it may be, it is there.

In fact designing a properly functioning sportscar suspension with ackerman and good camber angles, WITHOUT BUMPSTEER is nearly IMPOSSIBLE.

[dudocius240sx]

the way i see it, bumpsteer will always be there, you could minimize it but it will be there.

Especially if it's a macpherson strut setup.

There is a good series of articles in previous SCCs about suspension geometry.

[Matt Vassallo]

then why don't i feel it makin a difference at all ????


wtf

what im' saying is:

while it may be a problem, i dont' feel it at all when driving my car, that is lowered more than any s13 i know of except for teddys'. and he doesn't feel a problem either.

i think its something that internet mechanics make it to be a bigger deal than it acutally is, especially on s13s

[P_Productions]

Have a pic of "FanBoy?

[greazymule]

I have my d2's maxed in the rear and slightly lower in the front and i noticed what many refer to as "bumpsteer" after i dunked the shit out of it. i don't really notice it anymore and i think the fact that you're used to driving slammed s13's is the reason you are unaware of the existence of bumpsteer. I also am now rocking the SPLPARTS bumpsteer-reducing endlinks so i get none whatsoever!!

is your car really that low? i mean, you have aero and it is still on so it can't be that bad. or is it?

[piner]

yeah greazy comes close to ripping off the stock body parts hes so low

[Epstein]

Greasymule, how do you like the SPL bumpsteer reducing tie rod ends?

The bumpsteer geometry trade off that is made on the S13 is that the inner pivot points for the steering linkage and the control arm are located roughly the same distance out from the center of the car. This is the best case compromise for a macpherson strut setup that can't have all of the angles and lengths equal.

The reason that bumpsteer is minimized in most coilover shod cars is that the spring rate is so high. If the LCA/steering linkage barely deflects, then the effect is minimized.

If the S13 had zero bumpsteer, you'd be able to adjust the ride height without having to get an alignment.
