Well wasn't really planing on upgrading the suspension but since ITR Expo might be here in CA might as well start. So my question is which one is better Mugen or ASR. If any other bar is better please let me know.

 

There really is no better bar, like there is really no better suspension.

What is better is what your needs are for the vehicle and what you want the car to do for you.

Now to define that, What do YOU want the car to do for you?

 

Well I was really trying to find out the pros and cons of each bar. I want the one thats better for handling.

 

So that's a good start you want one for good hadling, ok, do you want the car to stick or do you want the rear to come out a bit when cornering. In other words how do you want the car to rotate in turns?

I gotta go but I'll be back later.

 

To bad you couldn't make it to the meet. Kiwi would have answered all of your suspension questions.

 

Yeah it sure does hopefully I can figure out everything I need to know suspension wise before itr expo. Is there an FAQ where i can read up on this somewhere?

and yeah sure does suck chamber kits didnt arrive in time cars still on jacks has been there for two weeks now. oh good news though found two people that i have delt with in sells that own itr's that are considering about going

 

Drive on track first. If and when you need more rotation, then look at the RSB.

Otherwise, use tire pressure to your advantage. More pressure in the rear = more rotation to a point.

 

Good point but I dont want to sit on it for a year. I would go out and track right now but I have no time atm going to school so cant right now. So ITR expo being around the corner and perfect timing say it will be in summer time frame I rather just wait till then. I also feel that itr expo would be a great way to start something Ive been wanting to do every since I got an ITR. So that being said I want to spend money on the car and rather spend it on suspension/braking upgrades then cosmetic things.

 

I my opinion just leave the stock swaybar for now.

 

Listen to dave, you absolutely do not need a 26mm RSB. When you're first learning the car you're doing to want it as close to stock as possible until you're able to start pushing the car to it's limits. Then slowly start upgrading to suit your driving characteristics/limitations/etc. I would be using stock springs/struts as well, I know that's not a very california thing to do but this whole thing is a learning process and you won't be doing yourself any favors throwing on a set of motons.

Save your money on seat time, the mods are a total waste for right now. If you take heed to this advice you'll thank me later. Expo is not even set in stone for CA anyway, hit some local events first. Seat time will always be your most valuable mod.

 

Where is the in car of "Move Over" at VIR with Mugen RSB installed?

Rene, that part will TOTALLY change the driving dynamics of your car. If you have very little seat time, I would highly recommend spending the money on additional track time vs. a rear sway bar that will most likely just get you in trouble.

 

Correct!


OP, I spent 3 years tracking on bone stock suspension before I started changing things. I didnt change until I knew I was at the limits of stock suspension. It takes a very good driver to find those limits. I now run a 26mm rsb but I didnt add it until I realized my driving style could utilize it. Experience is King. Dont think you can throw parts at your car and be fast. It doesnt work that way. Seat time, seat time, seat time. Your experience will dictate what parts are needed but dont feel you have to switch now or ever at all. You might find your driving style doesnt compliment any big rsb's. Its all about gaining experience first.

whoa, that's the first time I saw that. I don't know if that would be my favorite spot in the world to spin given the speed you're carrying at the top of that. Either way I hope the OP is listening.

 

Yes, good old up hill esses + lift throttle oversteer + Mugen RSB = not a pretty outcome.

This video is a great reference for those who think they want a Mugen RSB.

Steve, that is NOT a very good spot to spin at all. Easily done at 100+ MPH

 

Yeah after riding with jack friday I was trying to force myself to man up a little bit on those badboys. By the time I reached the top I'd say in my head "don't lift don't lift don't lift" at any point in the esses until everything was completely settled. None the less my favorite part of any track I've ever been to.


We're getting OT in fun talk. OP stay away from anything but the stock RSB for now. That money could easily be spent on a whole weekend, which will make you 200% quicker at expo right out the gate.

 

moral of the story.. dont lift.

 

Yeah I am listening seems like I will be going back to stock suspension as well. That's going to be another week the R is going to be down... Unless I can find a stock ITR suspension by tomorrow. Anyways any difference between the stock usdm suspension vs. a stock jdm suspension?

 

JDM has ever so slightly more springrate in the front. Otherwise, they are identical.

98 spec R had heavier 16" wheels and a 23mm rear sway, so the JDM car springrates were tuned around that. The JDM cars also had slightly more rear camber in stock trim as well.

Put it simply, they balance out for the most part.

 

i'm trying to think of a simple way to put this. when you get enough track time that you start wanting the car to behave differently, more rotation, stability, less roll, just the ability to actually state what it is you want to fix, then you can do upgrades since you actually have a goal in mind of what to address. before this point if your suspension is stock or you have a koni/gc package or whatever, you're still learning to drive and hone in on keeping your lines and brake/throttle points. once that's second nature you start noticing the brakes, suspension and tires much more. if you're one of those guys who grew up driving crazy on back roads it won't take you long at all to get the hang of track driving. the biggest difference on the track is how uniform everything is compared to back road rally. on the track you practice the same circuit over and over. it's a different experience.

 

OP I'm not trying to still your thread but, I have a question that will help you as well.
What is the effective spring rate ratio thing that differs between the rear wheel to front wheel. I know you take the spring rate and multiple by 1.?? for each. I ask because was going to put the JDM 23mm RSB (I don't have one at all and their about the same price) and have heard that running a stiffer bar can have an effect on your rear effective spring rate? Thanks. I can start a separate thread if the OP will like.

 

Easier said then done!

 

IMO, Kevins spin in the esses began because he missed the turn in point of the first of the esses. Trying to fight and keep the car on track was also a no-no. But maybe in the end, the RSB prevented him from saving it.... who could really say?

Other than that, I'd say DaveB is spot on.

 

Great thread for people like me who want to upgrade because I think my car needs it but I"m not nearly at that level.
