Nismo Body Brace Kit on a Roadster
 

Has anyone tried installing the Nismo brace kit on a roadster? Z1 Motorsports has some rather vague statements indicating that their may be fitment issues but their description seems loose enough to indicate they haven't tried it.

Any pioneers out there?

Well I've got my bracing in and will be installing it this weekend. I'd wager that 2 of the 3 braces will not be an issue... the third which connects the frame rails under the roof storage area might be an issue.

Nissan has a bunch of computers and hydraulics and crap down there ;) Pictures to follow if I'm successful.

That's right through the roof storage area isn't it?

Cool...

Now before someone else beats me to it...

:worthless:

Can you take some pics of the gear before you install it???

Based off installed coupe pictures I've seen it should be right under the leather draping... there's a large foam block in the coupes which is removed and replaced by this bar, that same foam block is present in the roadster which gives me hope.

And yes, the thread is worthless without pictures, but pictures are worthless if it clearly doesn't fit ;) If someone is actually going to go through the trouble to make it fit, they'll probably go off more than a rank amateur's dimensionless photos.

That being said, I'll probably end up taking them regardless.

Hopefully this will dampen the rear hip wiggle which I doubt is present in the coupes.

Have you done any suspension work yet? My coilovers almost eliminated all of the disturbing rear end activities.

Yeah, I went with the nismo shocks and springs as I was not interested in a drop, but wanted things stiffer. That absolutely changed the characteristics of the car but what I'm talking about is the high frequency shimmy which occurs when hitting mid corner bumps. It's too quick of a vibe to be suspension related, it's really just some fame shimmy.

hum... I did not want much of a drop when I changed to the coilovers either, I only have an inch drop.

I do know the shimmy that occurs in mid corner bumps, I hated it from day one. It is almost if not completely gone in my car after the coilovers...

Well good news and bad. The bad, the third doesn't fit, pictures will follow. The good, the front brace seriously plants the tires, eliminates a significant amount of front end push and in general feels like a stiffer sway bar was installed.

With only the lower rear brace installed, the rear shimmy is gone and the car is much happier putting down power exiting corners. Overall, even with only two of the three, there's a significant increase in the confidence and composure of the vehicle.

Can't imagine what the third would have done.

i was told the roof brace will not allow you to open your roof! and if your roof is open you cant close it!

why have the roadster if you cant open it!

lets see the pics!

Don't make me hold up the signs again...

:pics:

hey, :worthless:

Yes yes, I've been wrong here. Realistically they'll be up friday...had alot to prep for seca. Managed to win the lotto running over a razor blade and losing a tire, had to have ps2's shipped from reno. After thursday I'll be able to weigh in on track impressions of the two nismo braces and all three gt spec braces.

Alright so here's what everything looks like

looks good on this side, though I should note the lower bolt holes which were supposed to be presented were painted over by that flexible panel joining goop or simply missing. Rear bolts were present.

The two cat humps hang *extremely* low. ~2" of clearance midcar with this brace on a claimed .75" drop from Nismo springs... no more speed bumps in this car...
