Thread: B14 rear trailing arm movement?

I have a 98 Sentra and at higher speeds (50+) it feels like the trailing arm is moving slightly as i take corners, like fast freeway corners. it holds in the corners really well but if i were to transition from like a right to left turn or weave back and forth while still taking a long corner it just feels like 4 wheel steering almost. the rear suspension has megan coilovers, whiteline sway bar, delrin offset trailing arm bushings, and the rear toe is set to zero. still has the stock scott-russel link and stock bushings. i feel the sloppy bushings are whats causing it but before i had the toe set to zero it didn't feel that way. i first noticed it on the way back from west end alignment in cali to washington going through the highway corners in the mountains.


Still corners way way better with the toe set to zero, i highly recommend it to anyone autocrossing/tracking a b14 or if your going to be down near south cali. i am looking at buying the panhard rod to replace the scott/russel linkage, if anyone has done this let me know what experience you have had with it. thanks for any help/info

haha short story?

Offset bushings in the rear? That's a new one on me.

Who bent your beam? Sounds like something might have went wrong. After I bent both of my beams I saw only improvements and less roadnoise, no issues like you mentioned.

In which direction is the offset going? Is it moving the trailing arm up or down? And what would be the point?

sorry havent been on in a few days, but i had west end alignment in cali bend my beam. their supposedly very good at it, they are the ones that bent mike kojimas b14-15 race cars. the offset bushing pulls the connecting arms of the beam outward creating more rigidity

Your issue of "4 wheel steering" is probably because you lowered the car. When you lower these beamed cars, the thrust angle goes to shit, as well as you get lots of bind in the lateral link bushings causing all sort of weird shit to happen. Raise the car, I bet the issues go way.

Yeah they probably did it right then. How low is your rear right now?



That's probably it, thrust angle gets real bad if you lower the car more then 1".

As for the bushing binding, I actually was surprised to notice that lowering the beam didn't affect the squishy bushing nearly as much as we all think. I removed the rear shocks, then raised and lowered the beam, measured beam shift and watched the squishy bushing. If the beam was raised/lowered in the center (both wheels at the same time), the squishy bushing stayed fairly centered. That means lowering/raising the car doesn't increase the binding nearly as much as we think.

Once I'm done testing a few other mods to the beam I plan on doing a detailed write-up on my beam findings.

No need. I've already done the research. Here's my "findings":

The Scott Russell link type beam blows for anything other than going to pick up groceries. If you want real performance handling in a Nissan fwd, convert to a panhard, or better yet, a B13, asap.
