So there are a ton of chassis mods out there for out cars I was wondering which ones the members have done here and do you think it has made a difference?

I recently switched to a CR front sway and it has made a huge difference for my AP2. I however think it needs to be balanced out with the CR rear sway. The front tires really seem to be doing their fair share of the gripping now.

this is what im running now: neuspeed front + rear sway bars, 3 pt. strut bar, skunk2 camber correction kit, tein s techs. i also have a mild 3 pnt cage that hasnt been welded to my chassis yet.
- but all in all, i can def feal a difference. sticks to the ground more, turns more precise. cant complain.


welcome to RL9 btw.

RSB will help out with cornering a lot

My chassis mods:

ASR rear subframe reinforcement brace
ASR 24mm rear sway bar
Carbing front strut tower bar Type II
Carbing front lower arm bar
Carbing rear strut tower bar
Carbing rear lower arm bar
Function 7 rear lower control arms

Since my DB8 is a FWD, I had to focus my attention to tightening up the rear. In your case, you need to do the exact opposite. I would leave the rear sway bar stock. I would get a front strut tower bar and get a set of non-staggered wheels with some sticky tires. 17x9 with 255/40/17 tires is one of the best setups for cornering. The S2000 is already a pretty solid car, not much you can do about stiffening up the chassis.

The front Cr bar has really given favor to the front end and it feels like it needs a little push to the rear still. I'm still planning on getting the rear CR sway. Its not that big of a difference from stock but enough to where I will feel the difference. The strut tower bars don't do much for the S2000 unless you are to get a 4pt like the ASM or T1R and I am supercharging the car come late winter so they are out as I don't think they will fit. As for the wheels the stock set of staggerred wheels gives the rear a little more bite and I don't feel like rolling my front fenders to fit the 255s on. I plan on a 6pt (to avoid molesting my dash) an x brace, fender braces and maybe the ladder bar from ASM still have to do a little research on it...

My uncle with an 07 AP2 is planning to get the T1R front strut tower bar. Looks badass. A 6pt cage would be nice. Cusco maybe? I'm thinking of getting a 4-pt roll bar for my DC2.

Yeah it does. Have you seen the password 3 point front tower bar for your car? Major bling plus a guy I met that does autox has one and loves it. You should check it out.

I have the Carbing one, which Password copied.

I see! Right on!

Ofire Wrote:I see! Right on!

Yup. So do you do any autocross or road racing?

No. I plan on it however. We have a lot of canyons here that I cruise regularly.

Nice. I also touge from time to time.

Closed roads I hope!.... lol

Ofire Wrote:Closed roads I hope!.... lol

Public, but I go early in the morning when there isn't a lot of cars. I don't push it that hard at all. Maybe 6/10ths at the most?

right on. I'll get some pictures of my next drive. This canyon has banked roads like you wouldn't believe.

I think people are giving out generic answers. The S2000 isn't a civic or integra.

There is allready a HUGE ass brace between the front strut towers. There is also a rear brace from the factory. The CR has an additional brace but that requires removal of the factory soft top.


CR parts are really good for the AP2 chassis. The CR or AP1 (same deal) steering ratio rack, CR rack stiffener (cheap), CR springs and shocks (cheap), etc. are good upgrades.

The S2000 does have a X bone chassis..so it's pretty substantial. I'm sure there's room for improvement, but you don't really need too many braces. Some people really like the Spoon X braces for the subframe.

The approach:

Forget strut tower bars (OP allready knew this).

look into fender braces. J's racing braces are $250. That will be the only time spending only $250 will give you the right to put a J's sticker on the car. I don't like stickers...but whatever.

CR Swaybars are good. The 00-01 AP1 rear bars are 1mm bigger. I LOOOOVE my 00-01 setup. I'm not going to go in depth into my setup because it's late. I have videos and pictures up in the S2000 forum section. Take a look at the gingerman videos. My setup is the boss, IMO.

If you want more info, reply here.

A good coilover (I said good, not "sweatshop special"), or other good spring/damper combo, good alignment, and some track time are your best friends.

Track the car as often as possible. It's fun as hell and you'll learn something.

As a disclaimer, I do not claim to be an S2000 "guru". I do have a good knowledge about the car, and DEFINATELY have a setup that works very well. I set it up myself. I've had the car for 2 years. I've been to the track enough times with it that if I had to count, I'd have to take off my shoes .

Edit: Look under the thread "anyone else go to WMHM9?" in the S2000 forum. I put my setup in that thread. There are also videos of the car in action. The more I can whore the videos, the better I feel about myself.

P.S. you should have gotten a berlina. That's the fastest color.

Thats funny I beat an ap1 berlina the other day....!? I still plan on the rear cr sway and leaving the AP2v1 springs and shocks. They are suitable and I don't want to raise my ride height. I did plan on the J's fender braces... My next main mod is an SC of some sort. Either the comptech or the kraftwerks.... Just don't know if I want to throw 8 g's for the kraftwerks.... of course when they come out with the v1 kit...

The CR springs and shocks don't raise your car. It's a myth that generated because people saw pics of the CR with the spring spacers installed.

I think that if you plan on actually using the car (tracking it) without reducing ride height or sacrificing a lot of ride quality, the CR springs/dampers would be an excellent addition. Otherwise, I can suggest nothing but the KW V3s for a street car that sees track time. I love mine.

P.S. You could never beat my berlina AP1

There is a CR that comes on cruises with us and the front height is slightly higher than everyone elses. I thought they raised and stiffened the front to improve braking entry into corners? Either way the stock AP2 shocks/springs seem really suffecient at the moment. I've heard they are hard to beat aftermarket wise. I have also heard that a lowered s2 usually has slower slalom speeds. Even though if I had the chance I would really like to lower the car about an inch. However, I don't want to sacrifice handling or too much ride quality. If I was to choose a coilover the V3's are at the top of my list though!

P.S. Come to miller motor sports park next year maybe I could learn a thing or two from an s2000 who picks on poor civics! lol

lol I'd love to come out and crush civics with you all day....but I'm in the illnoise. You're in the Utah. Not gonna happen. Unless Miller Motorsports Park is in the madwest? Besides, those Civics in the video were on slicks and had engine swaps. Not "easy" prey...but I do have a RWD sports car....


Lowered S2000s probably have lower slalom speeds because fools over lower them, over spring rate them, and don't align them properly. There are also Roll Center Adjusters (RCAs) available to fix the car's inherent bump steer issues (toe out on compression causes oversteer...lowering the car will exxagerate this).

The guy who comes on cruises with you with the CR may want to check that his spring spacers are not still installed. There have been owners who have had them on their cars for 50k+ miles without noticing.

Have him check that there aren't rubber spacers between his spring coils. CRs are stiffer sprung, but not really any higher than regular ass S2000s.

I'd suggest the CR springs/shocks and alignment...but if you want to keep your stock AP2 stuff, more power to you. Saving up for the KWs would also be a great idea. I have my car lowered about 1.5-2''. So not quite hard parked...but low enough that old men at tracks scoff at me.

Yeah I really do love the KW's. Yeah that guy probably still has them installed I think all he did to it was upgrade the stock stereo and throw in a nav.

The article I read on slower slalom speed was actually Comptechs car. I was really dissapointed in their overall performance with the car. I understand their SC works on the higher end of the power band but I still expected to see an improved 0-60 but it was stock times. It really shined on rolling starts like 20-50 and whatnot but thats it. They had the comptech springs on stock shocks... so maybe that had something to do with it.

Miller motorsports park is here in Utah its a newer track but is quickly gaining fame in the racing community. The owner of the park (Larry H. Miller) had top designers assigned to the task of creating it and from what I hear they did a fantastic job. Look up the track on youtube. There is a video of in car cam of a BMW 328 following a Carrera GT and a supercharged S2000 right on the GTs tail. Its pretty awesome search "BMW 328 twin screw" Thats a local former s2000 owner and it is on that track.

I kind of like this forum over s2ki for the pure fact of feeling a little more exotic than most of the other car owners on the site. On s2ki you have guys who have way too much money who daily drive corvettes/porsches and track their s2000.

Well....I think that if you're looking for information on S2000s, this site has limited offerings. Again, S2000 ownership on this site is low...almost non-existant.

If the guy with the CR has them still installed, laugh at him. The dealership was supposed to take those out upon PDI or delivery.

I will have to. That shit is funny. I go to s2ki for information on the car for sure. Its nice to chat in a forum thats not jumbled with know it alls and kids who have s2000's and put NOS stickers on it. Know what I mean?

I would love to start playing with my S. I keep looking in my bank account and see $15k, but I think a house is a little more important right now that's what my wife wants me to say...

if I could spend my own money, I would probably have J's fender braces and KW V3s, probably a 3pt cage, then play with some goodies for the engine. Sounds like you know what you are talking about though!

Yeah does a 3pt require cutting of the dash?
Also the AP1 front sway is thicker but less stiff according to some posts in s2ki I've read. All of those damn engineers and their calcs.

hey hey. I'm an engineering student.

I don't know about the front AP1 bar being less stiff. I'd assume that it's made of the same steel, giving it the same stiffness and same K(spring constant).

Unless the link geometry, bracket placement, or LCA mounting points are different, the bar should be just as stiff.

Unless, ofcourse, I'm wrong and Honda did use a different type of steel or a different bar geometry all together. I doubt that, however.

LOL I didn't mean anything by it. That was going to be my career path too, Mechanical. I just had a tough time sitting in front of computers for long periods of time. So long story short... now I'm a fireman. Here is the link to their discussion I haven't read it all the way through. http://www.s2ki.com/forums/index.php?showtopic=599463

Man, there is SOOOOOO much bench racing on S2KI. Everyone talks so much about how they are afraid the car is going to behave. Driving fast on a track is really not as scientific as everyone on S2KI makes it out to be. They take all the fun out of even going to the track.

Who cares how the car will behave the first time out as long as you have fun. The S2000 is fast on a track stock. It doesn't NEED mods to go fast. It only needs them to go faster.

I took mine to the track 7-8 days after I bought it. It still had all season stealership tires on the back.

The whole "snap oversteer" issue only applies if you're TOTALLY a noob driver or an idiotic experienced driver.

I have an 00 AP1...the 00-01 is supposed to be the most misbehaved S2000. I'm sure it is. But that didn't keep me from passing up EVO MRs or Porsche Boxsters a week after buying the car.

I guess it helped that I had a sort of tempramental RWD car before...but it was still nowhere NEAR as tempramental as the S2000.

The OP of that S2KI thread was talking about correcting oversteer before he even experienced it or had the car on a track?!! WTF kind of strategy is that?!! What if the added understeer that comes on with putting in a bigger front bar slows the car down? He'd never know. He's going off a total whim there.

I think S2KI is a good site...you just have to sift through all the debbie downers, hardparkers, idiots, and anal retentive jerks. I can bet that there are people replying and giving advice in that thread that have never had an S2000 on the track.

If you mull over every detail and scare yourself to death before even driving the car...the track becomes WAY less fun.

To put it simply: Just drive the F'ing thing. Figuring out all the quirks is one of the fun parts. You get to LEARN something instead of just assuming.

But to answer your question, they said that the 00-01 bar is probably the stiffest and stiffer than the CR bar. I didn't realize that S2000 bars were hollow. S2KI is good for that kind of information lol.

00-01 front bar is 28.2mm with a 5mm wall thickness
The CR front bar is 28.6mm with a 4.5mm wall thickness.
