Springs. I have the type R front bar and stock rear 2005 bar. The rear bar is 19.1 mm, the front is 22.2 x 4.0.
Those are tiny bars. You can get away with softer springs for better ride quality and have the same roll resistance (lack of body roll) with stiffer swaybars.
It all depends on your goals.
Exactly and well said. Get a set of these they really make a positive difference and you will be surprised how effective the adjustable holes are for fine tuning.
Hrant, there is a slightly softer one he has at 300% these are 500% (over stock), you recommend the 500% ones?
I think I will need washers too now for the lower R chassis bar to clear.
I had softer ones before (the Comptech version) ......... stiffer is better :biggrin:
And with these you have more clearance to the battery tray but might still need a spacer/washer.

I've never had a problem with Dali either. They have the best assortments of bars out there.
I'm still waiting for someone to take some measurements for me of the stock bar so I can calculate the different spring rates of the Dali bars.
But until then, i'm kinda leaning toward the 1.0" Race (or Trophy) or the 1.125" trophy front bar with the 0.875" Street/Race rear bar.

Sorry, I have been in Detroit all week. Only had one day at home this week. Will get the measurements next week as I'm home Tue-Fri. I will get you the stock sways and the Dali 1".
What other measurements do you need other than what I posted?
Also when you say you are leaning toward the trophy are you talking about a recommendation for me or for your own car?
What did u post?
Ideal springs and swaybars depend on a lot of factors but I think that combination might be the best universal setup but am waiting for measurements of the lengths of the bar and its arms to calculate the spring rates in lb/in to be sure.

Resurrecting this thread, as I didn't see Billy's last reply. Billy, the KW coilovers are currently with Ravi. He is installing new swift springs. Current springs per your own evaluation of the numbers I posted are 1256lb front and 971lb rear. Ravi said that he was worried about going too far south or north of what was on there because that damper may need to see a spring within a certain range. He called KW and they said within 50% is OK, but not to go more than that.
I will change the sway bars per your recommendation to the Dali 1" bars. My wheels and tires are stock 2005 17" 215/40/17 and 255/40/17 Z1 Star Specs. Ravi made a spring recommendation, I forget the numbers but they were the same F&R. When I asked if we shouldn't keep the same "ratio" as the 1256/971 on there now, he mentioned the V3's come with identical springs all around. He was wondering if you had an opinion on it.

Not Billy, but this is what I just went through with Billy and KW.
KW's come with the same weight springs on all 4 corners out of the box. They will change them to your spec's.
I am in the process of switching to KW's with they're help of a sponsorship. Billy and I discussed the spring rates that I should get as well considering all the factors of how the car handles now, power, how I drive it, street and track use.
I ended up going with the KW Club Sports with spring rates of 857 front and 457 rears. KW told me the spring rates can be adjusted +- 100 lbs up or down without re-valving.
I run the 1.125" trophy sway bar upfront and a Zinardi bar in the rear.

Coz that's quite a difference front and rear. +/- 100 lbs is not that much, certainly less than the "50%" that I was told, but then we have completely different dampers.
My front bar is the R and my rear bar is basically zanardi spec. I believe in 03 or 04 the rear bar spec was changed to Zinardi spec. I am not sure why this is not in the wiki. But everyone here has said my bars are a bit too small. I will swap these when I install the dampers and sell my R bar I guess.
I'm just trying to get an idea of what to install for springs since it must be done now at Ravi's shop. I know worse comes to worse I can change them, but being he has to replace them now anyway I figured take the best guess... and hopefully I won't need to change them again.

Actually, looking at my notes, I was wrong, it's +-200 lbs. without re-valving. Still not quite the 50%.
I have been told that the KW's will be stiffer than other shocks that are set up the same, don't understand why when spring rates are spring rates, but that's what I've been told.
The best we can all do is get a basic setup that has been proven to work well with our NSX's and then go from there according to what we feel suits our styles of driving and what makes us personally comfortable.
My KSports were set up at 560/487, so this is going to be quite a change for me. Looking forward to seeing how things feel after I get them on. I will have them in about 2 weeks. I figure if I don't like it, I can change out the springs F/R either way somewhere in that 200 lbs.
Sounds like your on the right track too.

Thats what I've heard too Doc, the 400 split is ideal. Never tried it....and that poundage is personal preference on ride quality. Although stiffer they say is always better for heavy track use.

I would do 1000/600 for your motorsport 3-way dampers and do the dali 1.125" trophy front bar and zanardi rear bar. If the car pushes too much then go with the 0.875" rear dali street/track bar.

Spring rates don't matter. Wheel rates do. It depends. Can you avoid most of the pot holes and broken roads? You already went with the more race oriented KW 3-way motorsport dampers and not the KW V3s. It shouldn't be terrible, you can crank down teh highspeed compression which will help.
I'd say try it and go from there.
OK will do. I can try to avoid most of those roads but they are everywhere. Winter time any water freezes and cracks the streets and pavements. It's a yearly battle here. But I don't daily drive the car. I can handle a bit of harshness on weekends I suppose. I'm sure I will love the feeling versus stock on handling and steering response.
I'm leaning toward the Dali .875 rear instead of the Zanardi because although $50 more, it is adjustable and the zanardi isn't? anyone think I won't need that feature?
God this is costing a lot... first it was the suspension, then the bushings from tidave to complete it... then a VRH so I can clear things... then new springs, now new sways... WTF!!! :biggrin:
