i feel that the car is quite unstable at speeds in excess of about 120km/h. one of the tracks i go to has a 5th gear main straight. generally i hit about 200-205 down there, the car feels very unstable once past about 130, and positively dangerous once past 180. i'm wondering if any of you wingless people have experimented with adding wings, lips or rear valences in the quest to improve stability. i was thinking that maybe a type-r wing would serve a purpose here. pitty they are so ugly
anyway, my suspension is reasonably well sorted, and i don't want to drop the car any lower than it is now- due to clearance problems. i feel that the problem could be helped with some aero aids, unfortunately i'm not sure where to begin.

any help would be appreciated

 

you might want to check your tires. if tires/wheels arent balanced that might be a factor.

 

i've played around with lot's of different wheel allignment settings and my wheels are balanced...

it's something inherent to the car. i've driven a civic hatch, it was evern worse- i guess the flat back creates a bit more turbulence...

 

ive taken my DA to 120+ and the car felt solid as a rock. maybe the factory wing played a part in this. i would think a Hype R wing might improve your downforce and you might look into a front spoiler too.

 

I swear the steering is too touchy on my integra (stock.)


A bigger ps pulley may help in my case?

 

My LS feels solid and stable when going up to 135. All I have is H&R race springs and fairly new tires on my LS wheels. i dunno...

 

my integra does not feel solid at high speeds at all, over 100mph the car just feel too light and not planted. But I have taken off my stock GSR wing, lowered it, and have no lip, valences, whatever.

 

my car feels like its going to fall apart going throught the jack n' box drive through.

i probably need more downforce.

 

last time i had mine fairly up there.....i was at 90mph and that's about when you can feel the rear end start to lighten up quite a bit. makes for a scary time i'm sure a wing would help in the back (something like the ITR or mugen)

you are talking about km/h. the rest are talking about mp/h.

 

I have a 96 Integra GS-R, and the last race i ran, i hit about 130mph, and i never noticed that it felt sketchy or loose at any time during the race. I dropped the car 2 inches, and threw some Tokico JDM ITR shocks on the back, and i left the front shocks alone, just tossed some drop springs all around. I did replace the LCA's with JDM ITR LCA's, and they actually did make the car feel a bit more stable over when it was stock.

Then again, i was spraying, so it didnt take long to get to 130mph, so maybe i didnt notice cause it went by to fast.

 

when i had my 92 RS-HB i had it upwards of 125-130 and it was all stock. i never felt it was unstable. maybe the little stock wing does make a differance

 

My car is lowered 3", no wings or lips or anything. I've been up to nearly 230 kph and it felt stable the whole time.

And no my rear wiper did not flip up either.

 

130mph in my lowered DA= ...................... 120mph in my stock GS-R=

 

i think i need some sort of front end work to the car. stop all the air from rushing underneath at high speed. maybe a lip would be beneficial.

the lack of composure at high speed is deffinately not in my mind i've noticed it for ages. it only really started to annoy me last night since there was no traffic, and i could take a fair ammount of speed down the motorway. it got really tiring after about an hour. i ended up slowing to about 120km/h. i've driven cars that are worse at high speed. but not many


i might experiement with moving my konis to the lower perch setting. i don't know how much it will help though.

 

Your sig references a caster kit is fitted to your integra. We regards to high speed stability, caster would have the greatest effect. What kind of caster setting are you running? If memory serves me correctly you'll want to run more caster to gain stability. Also what kind of toe are you running, try 0 toe to gain stability.

I'm running as close to factory spec as possible on the alignment as possible and I have no problem with stability. Generally cruise to work @130km/h. Yes it's different in a race enviornment but I wouldn't feel that high speed stability would a problem.

 

Honda engineers aren't stupid I'd follow the type-r route. front spoiler (valence, lip watever) rear wing, rear lower spoiler, and wider tires...that should help with high speed stability. You're better off with a different (wider) car if you want something with better high speed stability and handling.

 

Seems like a lot of these guys think their car is "stable" if its not rolling end over end in a fireball of horrific death. I personally think the Integra is very twitchy at high speeds compared to German counterparts. It would help if our power steering wasn't so hyperactive at high speed. Also, when wind is blowing hard from the side (perpendicular to direction of travel), maintaining control can be... "interesting" rather quickly.

I'm thinking that might be a typo. I've never seen a kit for a Honda that allows adjustments to caster. It would have to move the upper control arm/balljoint forwards or backwards in relation to the lower control arm/balljoint, which would tilt the spindle forwards or backwards, changing the angle of the steering pivot, thus changing caster.

But maybe he does have one and I've just never seen one before. If so, I'd like to see what it looks like.

 

I have a 91 LS 155xxx miles completly stock 100%. No rear spoiler, nothin
Not lowered or anything. And I can honestly say at 100mph, the fastest I've gone in it. LOL. It is one of the the more stable cars I've driven.
It just feels very planted to the road. And this is a car that's almost 13 years old. Compared to my CRX's it feels almost truck-like. And I wouldn't
exactly call the CRX's twitchy in general. Although, if the conditions are right they can be. But in my experience the integra seems very stable at speeds up to 100mph.

 

not a typo
i'll get some pictures of the "castor kit"- it's really some larger bolts and a few washers. i'm running about 4 degrees if memory serves correctly. i'll have to go trawling through all the bits of car related paper to find it. i'll get some pictures of the setup. it's fairly common practice over here for track EG's and DC2's.
i noticed the twitchy-ness of the car when it was bog stock, it is much better now, but still not as stable as i'd like. to put it simply, i think cruising above 150km/h (94mph) is not safe in a stock integra. maybe i can get about an extra 25km/h out of it now...

the castor didn't really effect stability (i changed components one piece at a time). the effect of the castor seemed to be more on mid corner grip than anything else. it had little effect on turn in, apart from making the steering a little more heavy and the car a little more prone to tramlining.

... and yes, despite the car tracking well enough straight ahead when cruising at warp speed, the car does not feel stable i find it to be very twitchy and nervous. i feel as though it is not much better than my old corolla was.

i guess the old generalisation about japanese cars lacking high speed stability is true...

 

Integra vs CRX = "integra is stable"

Yeah, sure, compared to a late 80's (?) economy hatchback! But let's do this comparison

Integra vs 330i = ?

you tell me. I haven't driven a 330i. But I will say

Integra vs Passat V6 = Passat is at home above 85 mph.

Ben

 

i actually made the comparison due to having recently had a cross country drive in my dad's e class. it was rock solid at 160km/h.
i've driven a mk4 golf on the same stretch of motorway that i was showing the integra to be unstable, the golf felt a little worse if anything.

... i guess it's not fair to compare an integra to cars that cost 10 times the ammount

This is one of the most short-sighted overly subjective un-informed things I have EVER read.
Well, I never drove Michael Schumachers' F1Ferrari, either but I'd bet it's more "at home" over 185mph than either a Passat or an IS 330. What's your point?
The Integra is a stable in my opinion. Not compared to a 1980's "econobox" but to the cars that are raced constantly throughout the world and win with their 1980's "econobox" double-wishbone F1 derived suspension that is still coveted today. Yes, I think you're right, I overstated the capablities of the Integra. It IS highly unstable and all of you should sell yours before Ralph Nader makes a scathing expose on how they are "Unsafe at any speed" LOL (honda is waiting for this)
And to add, its sort of unfair and kinda of impossible to compare Integras
to cars that didn't exist when they were designed. And, thats not even taking into account that the the IS 330 costs 2X the price of an Integra.
What was the point of your post again? To say IS 330's and Passats are better than Integras?

Now that's just not very nice. Its posts like that which get threads locked or deleted. You need to take a chill pill man. Weren't you the one ranting and raving the other day about how people refer to cars as people and you just can't stand it? Whatever man...

The point is, a lot of the people here are saying the Integra is super stable. But if you haven't driven other cars, how do you know? The Integra has over-active power steering at high speeds. I would guess it would be this, and the increased wind noise and the torqueless engine and all-in-all less dampened driving experience that make an Integra a less stable-feeling highway cruiser than a German sedan like a Passat.

And I said 330i, which is BMW 330i, not Lexus IS300, you ****.
