Sway Bar Stock?

Actually for autocross use in the SCCA Street Touring S class in my
91 Sentra SE-R, I used to have a problem with lifting the inside front tire
on corner exit when running with an ST rear bar and a Stock Sentra SE-R
front bar. I put on a Stock Sentra SE (not SE-R) front bar after I found
that the Sentra SE Front bar is only .5 mm larger diameter than the SE-R bar
but is also hollow making for a 15% softer front bar. This made the car lean
a bit more (Not much) but also gave me that ability to get on the throttle
much sooner. I would not recommend doing this though unless you have the
ability to dial in at least -2.5 degrees of camber to prevent positive
camber mid-turn and also stiff enough spring rates and lowering to help
control the "sway" and an upper strut bar to help prevent some of the
chassis flex.
Oh and speaking of an upper strut bar, Ground-Control has finally
made an upper strut bar for the 91-94 SE-R for use with their camber plates.
It fits nicely in the mounting holes on the front of the plates and seems to
give the front end a much more solid feel and a bit better "turn in". It is
not on thier web page but there are 2 of us out there at least who have them
on thier cars.

my life.

Shocktek and finding them out of business. Surprisingly, I think the GC/AGX
combo works better than the Shockteks did, at least for autocross.)

A few people that I know said with an aftermarket front bar, one wheel would
almost lift under hard cornering thus causing too much wheelspin. When they
went back to the stock bar, the problem went away.
Lee K. did it in an NX2000, Wade Jackson did it in a 200SX SE-R.
However, Larry MacLeod ran an ST bar on his 200SX SE-R and said it helped
him a lot. He was autocrossing in a stock class, though, so maybe that one
mod helps when you can't really touch any other suspension components.
<shrug> Lee K. and Wade have coilovers and whatnot.
Ideally, you could test both bars the same day at an autocross or open-track
event to see what's best for you. :)

You have to get a new set. ES bushings for the front bar are only $15 or
so.
