Is everyone cutting out one bump stop when dropping their G Sedan? How low does the drop have to before the need to cut one out?

Dont forget, a bump stop in a suspension is usually a certain height in order to keep the a-arms from hitting the frame or something. Cutting those shorter, or taking them out will make a loud bang when you go over a big bump, bend something, or both. Just make sure everything clears when the suspension is fully compressed and extended after making any adjustments to the bump stops.

I cut my bump stop.. Since you are shortening the travel...you should also cut the bump stop your the ride will be bouncey... well for mines I had too...

I have the coupe, but I did remove about 1" off the front bumpstops upon
installing the S-Techs. I haven't had any issues with this and TEIN
instructs the installer to do so.

How can you cut a bump stop that is built into the dust sleave. You can't cut the bumpstops on these cars unless your willing to cut up that dust sleave, something that is unexceptable.

Frankly, given that most of the springs out for the G don't lower past 1.5", cutting the bumpstops is not needed. And if you hitting the bump stops for some reason and it's causing ride quality issues, you have a mismatch between ride height and your shocks. Either make another spring choice or install proper shocks that can control the suspension correctly.

Gsedan35- are you talking to me?
On the coupes, you can just push the bumpstop out of the
boot, cut and push it back into place. I haven't full stroked the shock to
where it would hit anything or bottom out the car. Most cars come with close
to 2" of clearance anyway.

Wouldn't the Sedan be the same? You can literally cut out one of the bumps on most Nissan/Infiniti products and put it back. Can a Sedan owner confirm?

I'd blame the overall spring rate in relation to teh ride-height. The shock damping is only one aspect. If a suspension is so low that travel is shortened, I'd actually make sure the spring itself is better matched to limit suspension travel and then match the shock to the spring/sway-bars. Stiff sway bars can help reduce or fix a bottoming issue if it's occuring while you hit bumps in a turn by reducing the amount of travel that is taken up by body roll.

However, cutting bumpstops or at least going to shorter, stiffer ones is a good way get a little bit more suspension travel before hitting the bumpstops on a lowered suspension. Since a well matched lowering spring will typically have a higher spring rate, you can get away with a shorter bumpstop. I've always cut bumpstops on every car I've lowered. Most bumpstops are sectioned. Cutting the smallest softes section usually is enough. There are some suspensions that do not need to have this done at all as the strokes are very long even when lowered.

I changed my shocks this weekend & looked at cutting the bump stops (SEDAN)

FWIW..
I don't know if the sedan uses a different stop from the coupe,
but from what I found I don't think it's advisable to cut it.
The bumpstop has a hard retainer ring at one end that maintains the integrity of the stop when compressed.

If it is trimmed off i think you will ruin the stop.
Also the material is fairly soft, I could easily compress it in my hand to half it's height.

Again, I'm not sure if the sedan is diferent, but
if a shorter stop was required, I'd be more inclined to
get a new (shorter) one, than cut up the original.

Here's a pic with the stop removed from the dust boot
