Will a Nismo swaybar for a 2007+ coupe fit a 2005 roadster??

 

Yes- but I hope you're using both F&R swaybars.

 

Are we talking about a stock sway bar? I'm going off the assumption that the stock sway for the nismo isn't the same as the aftermarket S-tune, if it is don't do it it's softer than the stock one.

 

I agree with DK, I went with Hotchkiss on my roadster bc of adjustments.

 

Its against SCCA rules for autocrossing. Front bar or REAR bar ONLY, not BOTH.

 

Ah, updating and backdating the front swaybar, eh? Then we're not talking about the NISMO S-tune bar. Any OEM bar should fit just fine..

 

I would try to get a pic just in case Nissan decided to use the S-tune stuff on the nismos. They look super similar, adding a softer bar with a stiffer front would lead to too much understeer I think.

 

The guy listed the bar as OBO, came down 2 bucks. I went with a Hotchkis front bar, should be delivered this Thursday.

I was planning on going to a local test and tune Saturday, but since FedEx "LOST" two of my new tires, I am getting those two mounted on Saturday instead.

I did replace the brake lines with Power Stop braided stainless steel (D Street legal) and am running four 17x8 stock wheels with 245/45/17's It should eliminate the front understeer and make it a much more neutral balanced car.

I don't expect to run TTD just enough that the wife and I can have a good time. She remarked that she misses our old Corvette, since I had already done everything to it, and we could just go out and run autocross and HPDE. Stitch (since she is a Roadster) is just a weekend autocross and back road toy. But I still want the best that it will do.

Bilstein shocks will be next. I just have to work OT to pay for them.

 

For those that run the Hotchkis bar, it looks like it has five adjustment settings. Which one do y'all use?

 

My bars have 3 holes as I recall. I run on the softest setting/closest to the end for street use. If I'm driving hard in N Ga or NC mountains my lip will scrape on hairpin turns so I may go to the middle/medium setting this Spring.
If you are using aftermarket end links (Whiteline) be sure as you install them the length is static- neither pushing the chasis up or pulling it down. You don't want pre-load on the sway bars. Gl!

 

Front: Hole 1 of 4 (towards end) = softest
Rear: Hole 2 of 3 = Medium

This setting is biased towards mild oversteer. I started with full soft F&R (which is already stiffer than stock), experimented with what I like all the way up to full stiff. For my type and style of driving, I like the above best for street/highway, hills runs. YMMV. I always recommend this method of testing to see what works best for YOU.

 

Gentlemen,

I am ONLY replacing the front bar, both sway bar replacements are NOT allowed for D Street. I will try it on medium and go from there.

 

I used the 3 stiffest when I had mine, since you are using a stock bar in the rear I'd start with the softest and see how it feels. The softest is still stiffer than stock IIRC.

 

last I checked, you could replace the front or rear bar

 

I should have been more specific, front OR rear bar. The last thing I want is more rear bar to increase roll stiffness in the rear in a car that already understeers. Front bar to help reduce understeer. Between running a square setup and more front bar, it should make it a more neutral handling car.

 

More rear roll stiffness creates more oversteer. Enabling the rear tires to achieve (or approach) max slip angle before the front, leads to rear tendency to “come around”.

Same effect as a square tire setup. Done to promote oversteer/reduce understeer. Front tire with same width theoretically creates more “grip bias” to the front, hence the rear achieving max slip angle before the front’s increased grip

The Z’s OE setup was purposely staggered to let the front wash out (understeer like a pig) before the rear, likely to avoid product liability issues (speculation).

 

Because of all those Lewis Hamilton wanna be's who think that because they can play Gran Turismo they can be fast in any car. And when they total the car, well obviously it's the car and not them. Yeah, I've seen lots of that over the years.

Bars here!

Install will be Saturday morning

 

First time I heard of a stiffer front bar increasing oversteer, it will increase understeer lol.

 

Swaybar is on. Took about 45 minutes from wheels up to wheels down.



My size XL *** under the car.
