Following up on my setup (after about 2.5k miles since my last post), the
rattling from the endlink was beginning to be more consistent above
20mph over uneven roads, so i decided to to swap out the endlinks...but
the problem was i couldn't get the top nut on the endlink to loosen..
so endedup ordering new brakets that holds the endlinks to the chassis.
($28.50 each). Parts won't be here until later in the week.

Meanwhile as a temporary solution, i changed the rear swaybar setting back
to med. The noise from the endlinks (the originals) are no longer there
and the car actually handles better as my car's alignment was setup with
this swaybar setting (soft front/med rear).

I will be using this setup until the endlinks start rattling again in the med
setting which may or may not happen.

that's an interesting setup having the rear swaybar harder than the front. I ususally go softer vs the front in the rear to get more rearwheel traction during and existing turns.

i think your setup is more unique as the car tends to understeer when
the front swaybar is setup too stiff vs the rear.

it's not to the extreme of having the front full hard and the rear full soft. I have it at soft in back, med in front. our school's formula cars are setup similarly. and our schoolds FD has largus swaybars...we replaced the rear one back to stock and have had really good results.

can't compare your car to your formula cars as it's not even close to how
the cars are setup. but watever works on your car is fine with everyone.

this is a thread on how my cars is setup.

the car comes from the factory with understeer bias and quite a bit of
roll which is fine for the factory narrow tires. car doesn't want to turn
tight corners with the factory setup though; this is one of the reasons
why i have the rear set stiffer than the front and the other alignment
settings... plus the tires, etc.

yah...this thread is about your car, but you expected feed back right? otherwise...why even write about it and not expect any?

I didnt write that your setup was bad example or anything like that...just that it's interesting.

As the saying goes, "what works for you may not work for me" and vice versa.

changed the front swaybar setting to med.
added ARC front stb a few weeks ago.

i was expecting mild understeer from the front swaybar setting from
soft to med, but since it helps the car's posture i can make the rear
drift easier (not that im a drift0r or anything). a nice surprise for me.

It's been said that you need to stiffen the front bar to induce oversteer in this car. Can anyone else comment?

I think Dan's right? I haven't heard this... but know our cars understeer a lot... and the last thing you would want to do is stiffen the front sway bars... but just as an experiment I stiffened my front and I actually like the turn in better.

Anyone else know anything on this???

Its odd that a setting against logic would be the one that feels better on the street in some fast corners...

the issue is that the overall front springs are too soft and basically
forcing the swaybar to do part of the spring's work. that's why stiffening
the front improved the overall posture of the car, thus enabling more
potential out of its programmed suspension geometry.

we have to remember that we are working against nissan engineer's
suspension philosophy when we lower the car for dress up. that area
we are just compensating with other bits on the car.

if you were to use higher spring/damp rates overall and use stiffer front
swaybar setting you will eventually find a point where the car will understeer.

the lowering spring setup with my D-specs set on the conservative
side still has A LOT of margin until you get to that understeering point.
that's all.

Kenchan, are you a programmer? Due to the pressure //comments I was half expecting to semicolons instead of periods;

Ken, curious what offset sizes you have and tire sizes you are currently running? Also did you have to roll your fenders in the rear? I know the fronts are done already from the factory.

I have 19 x 9 and 19 x 10s setup identical to yours... and am running 255/35/19 and 275/35/19. I'd like a straighter sidewall and more rim protection but have been worried about the rears rubbing fenders without them being rolled.

Also, if I don't roll the rears... How do you think handling will be affected if I continued to use 275/35/19s in the rears and only upgraded the fronts to 265/35/19, as it looks like those will fit without a problem in the front fender...

Just didn't know if the front/rear difference in sizes being so close may make car understeer more or something else??

Thanks!
