Comptech sway bars

Dave, your analyis is mixing apples with oranges - the comparison is not valid IMHO. The track 1" sway bar works well with most of the supsension options out there for the NSX; it is a proven and tested product. And a poll will not change my mind:tongue:

Why isn't the comparison valid? Where is the flaw? Seems logical to me.
 
To put it as simply as possible, the NSX's suspension is designed using 1989/1990 technology with very minor changes over the years regarding damper and sway bar changes. It is not a McLaren or anewer technology supercar which was your reference. You work with your given baseline which is mostly changing the spring/dampers and sway bars.

If you are not going to track your NSX, then you don't need the 1" track; but I can assure you even if you don't track it, you will appreciate the improved steering feel as well as the stability on/off FWY ramps:wink:

Took the words right out of my mouth. So who do I have to kill to get me some trophy bars???
 
It may not be a McLaren, but I don't think that takes away from the fact that a sway bar does indeed decrease suspension independence. Do we not agree on that?

I also made several other points... Harsher ride over any bump that does not equally affect both wheels, and no control over squat and dive. Obviously there is some matching that needs to happen, and although I have no technical facts to back this up with, it seems to go to the stiffest sway bar available while using springs that are just mildly stiffer than stock may not be optimum. Of course I don't know, but I don't think I'm way off base with the assumption.

My sleuth grapevine informant says the sway bars will be available in a few weeks - they are being powdercoated:biggrin:

The OEM sway bars were (and still are) inadequate whether one tracks or not even for street driving; the NSX has more perfomance in it than the OEM sway bars can handle. You have changed your suspension so jumping to 1" is not that huge of a change if you like a more performance supersports type ride (not GT). As for the rest, as I said, if you will not track your NSX, you don't need the 1" trophy; the CT should be fine.

If I were you 1k2go I'd consider doing both, up the spring rates, and do the bar.
 
There seems to be a 1" track bar, and a 1" trophy bar. What's the difference? And then there's the 1.25" bar. Should I do front or front and rear?

The reason I am asking about Comptech is that Nate will give me a great deal since I did the supercharger GB for him. I thought because I already have such stiff springs, it may be enough.... But sounds like you guys think it won't?

Dave, given your relation with Nate/CT - ask Nate to make a 1" adjustable sway bar. Nate needs plenty of sweet talking to start a new product ......... but the template is there.

More than likely I will but I like to do things in stages so I can see the results from each upgrade. I like a relatively 'loose' car so I will do this in stages. I'd like to upgrade my CT bars to 1" trophies, starting with the front first before I go to higher spring rates, but inevitably I will likely change the springs too.
 
I originally had the stock rims with Falkens and spacers. Car looked awesome but on my first canyon run was unnerved by the push understeer I experienced. I mean scarey. Upgraded to Enkei RPF1 in 17/18 and felt a big improvement. Then I upgraded the springs to the Tanabe/SOS progressive lowering springs with Bilstiens on the lower perch. Very nice improvement all around with no more diving and especially the squatting with the new performance because of the turbos. Still a little bit of push but that was because of extra speed. I got the Trophy 1 1/4" and set it at the most moderate position. OMG, the difference was night and day.The car is flat, the front sticks like glue and I can control the tail with just my right foot. Do I notice a little more of the road like bumps? Yes I do. But the turn in and response to steering input is like flying a helicopter. All I have to do is think about where I want to point the car and it goes there. The NSX needs a big ass sway bar up front and very little in the rear. I've read that some race teams took the rear sway bar off. I left the rear OEM but upgraded the bushings. The car is now neutral and goes exactly where I point it. I love the Dali product. First class. And then I add Jeff's Carbon6 Non-compliance clamps. That front end is tight perfect. The canyons are awesome with this setup.View attachment 99948

The 1" track bar look like the twisted OEM sway bar just thicker. The trophy par is straight with the end bars welded at a 90 degree angle with three adjustment holes for your end links. The Trophy bar will not accommodate a spare tire as it goes right above the pan. But it is stout and much stiffer than the "Track" sway bar.

The Track bar looks like a slightly thicker version of an OEM sway bar. Will you notice it? Probably.

The Trophy bar is a straight bar that sits on top of the pan and has two flat bars that are welded at 90 degrees to the end of that bar with three adjustment holes for your end links. You won't be able to fit your spare because of it's location but it is way stiffer than the "Track" bar.

I know what you mean... But there are a couple of issues that will remain. One, it won't cure squat and dive. Two, a really thick bar can decrease grip on the outer wheel. Essentially you have less independence. A lot of the newer supercars like the mclarens choose to not use them alltogether.

- - - Updated - - -

Also, it will increase wheel rate so if only one tire goes over a bump or pothole, you are going to have a worse ride. It's certainly not without penalty. I get what you're trying to achieve, and I am not saying I know better, I'm just thinking a 600% stiffer sway bar with springs that are roughly 75% stiffer over stock is what we are looking at. I'm thinking that may not be the best match/compromise.

The McLaren has an active connected suspension that can give the characteristics of a sway bar and vary the magnitude. Many reports don't like it and say the Ferrari 458 handles better with its standard bars.

If body roll and oversteer are not issues, a much bigger bar is not as crucial.
 
I was really hoping you'd still be around Billy. I'm going to do whatever you suggest here. So if you remember, this is my setup:

215/40/17 front and 255/35/18 rear. advan RSII whelels, Yokohama AD08

KW competition set to all the settings you gave me. 150 psi and whatever clicks you told me. Spring rates are 1000 front and 600 rear.

Alignment set to your recommended "my personal settings" on your alignment thread.

All of Dave's non compliance stuff.

Car is not a daily but just a weekend car, but see a few track days a year. Maybe 5-10 days. Otherwise street driven in Boston.

Current front bar is type R bar, OEM rear bar which for a 2005 I believe is identical to the zanardi rear bar.

So my choices are either Comptech bars, or any of the Dali bars.

Can you tell be what you would go with if you were in my position? Front and rear? As always, much much appreciated.

Dave, I am not one to get offended easily, but you may want to be a bit more pc with your comment.

..... Billy recommended the Dali trophy bars but it seems like that's not even made any more or in stock.

Comptech bars say "300% stiffer in middle setting". Dali is 500 and 600 on the trophy 1.0 and 1.25. I am runnin 1000/600 springs.

Billy is right on. A few of us who responded and who have tried the option, and use their cars pretty much as you do, said pretty much the same thing (the 1" Dali Track bar is a better option for you) by giving you more details. As the link I referenced states, the trophy has fitment issues and may not work with your radiator duct if you have one. But if you want to milk this question more, sure, go for it. A poll might give you some options for a group buy too :biggrin:

Some of us enjoy the trial error process/journey because we learn more from it than what the OEM manual states :tongue:

Please show said reports. The McLaren 12C's hydraulic F1-derived suspension (banned FIA technology) offers a compliant/comfortable ride at cruising speeds ("Rolls Royce-like") yet firm/responsive ride in performance arenas. It's been univerally lauded for such. A few magz-ragz journo yahoos couldn't power-slide it, so they slammed the handling/ride characteristics. The 12C (due to namely its suspension) is annihilating the 458 in any/all metrics & parameters like no Ferrari has ever been beaten. It's obscene & gruesome to say the leasts. Not a single enthusiast nor gear-head in the know would prefer the 458's suspension/handling over the 12C. The only beef anyone's had w/ the 12C is the sound/styling/soul dealio, which is all subjective...

Hrant Why would you be offended? Because i said i would just go with billy's suggestion? What do you mean "be more PC?" Billy knows my KW's better than anyone. It doesn't mean I don't appreciate others' input. Maybe I'm missing your point. If he doesn't get a chance to answer I'm going to get one of the Dali bars. I'm unsure what to do in the rear. since we are talking, I will ask this again, can you tell me what the difference is between the 1" trophy and 1" track in terms of performance and fit? I can talk to Nate like you suggested on a 1" but I'm not sure they want to introduce a product similar to a well selling one already on the market.

Which holes are you using out of curiosity.

Dave, no offense taken - I thought that was clear from my post. But it was an editorial suggestion.

As for the difference between the track vs trophy (click the More Info tab): http://www.daliracing.com/v666-5/catalog/index_browse_part.cfm?focus=1407

Regarding which holes, this is somewhat dependent on the your driving style as well, and tire/suspension. But I can assure you that you will notice the difference of a change in one hole at the track - especially if fiddling with the rear sway bar.

So the track bar sits under the tray and the trophy over it? I don't have a spare, I have a type R hood and but I do have the downforce scoop in there.

That is correct. The track bar sits in the original position as the OEM sway. The Trophy bar sits on top/above the pan but resides in the same mounting points. You don't run a spare so no fitment issues there and I doubt the R hood and ducting will be an issue either.
