I've heard from several of people that EF do not handle as well at higher speeds(85+mph) when compared to EG/EK chassie. I understand each car is going to have different suspension setups but as a general statement, people say the EG/EK design are better for high speeds.

Not many people will consistantly see 85+mph in their civic but during Road Racing conditions tracks offten have a long straitaway where cars can easily reach over 120mph.



Questions:
1) Is that true & if WHY (which part of the ef suspension is the major weak link)

2) Does getting aftermarket suspenion parts (coilover, camber kit, swaybar, strut bars, ect) even the playing feild with othter suspension modifyed EG/EK? or regardless of suspension modifycation the EF will always have it's drawback.

my personal opinion. when i had my d15b2, i was able to hit 125 on the freeway on the way to san antonio and it turned and handled like a bike on crack lol

 

get energy suspension kits, all new inner outer tie rods, new upper ball joints, new lower ball joint, for me i got stock suspension with lowering springs. this is one way to make your 20 yrs old car handle better.

 

You really shouldn't be going that fast on the streets.

Edit: Sh!ft

 

is a highway still considered a street??

 

Take it to the track if you are planning to speed at that speed.

 

It's true and false.
1. You're talking about a car that's around 20 years old... 90% of the people who own them are clueless about suspension set up, let alone have the car properly maintained.
so, having a "stock" CRX/Civic, is still likely running on very old suspension components which isn't exactly the best for high speeds.

2. CRX Coefficient of Drag = .29/.30
92-95 Civic = .30-.32
The CRX is more "aerodynamic"

3. the weakest link of the suspension is this... It's FWD and, in the CRX's case, it's got a short wheelbase, which is not the most ideal for high speed stability, but works great for cornering.

a CRX will always be faster around a track than a similarly prepped EG/EK. Mostly cause of it's weight, but as mentioned above, their ability to corner makes it quite agile. the ED/EF civic is different, due to the longer wheelbase...

bottomline, whoever is telling you ED/EFs don't handle as well as others... don't know what they are talking about.

 

No hahaha dude wat u heard is bs all you mainly need is some suspension i have skunk2 full coilovers. I had a b18c1 and I'll top that thing out on the freeway and my car handeld clean. Just upgrade ur suspension.

 

I believe this is what your question comes down to.
If you fit the EF and the EG with the same spring rates, same shock valving, sway bar stiffness, bushing compounds, etc, blah blah blah -
What's left is the final geometry and chassis differences.
Things like the EG not using the front crossmember like the EF does and small things like LCA lengths all have some impact.

Good question - I have no answer though - please keep this thread updated if you find anything out!
Not even sure if there are people on HT that have that knowlege.
Maybe somebody in the road race forum has dissected the two chassis and figured it out?

 

while doing 130mph my car felt fine, only everything was louder. while doing triple digits on the track my car handled great.

but the only way to really answer your question is to have a side by side comparison of each car on a course using the same driver, either stock or with the same modification. asking individuals will only give you bias results. better yet, see if you can find some new car test online.

 

Where I live, which is about an 11/2 south of detroit your average commuter goes 80 on our highways. so goin 85 is no outragous speeding. If you have a quick car that you like to have a lil fun on empty roads with it is easy to hit 85 before you know it.

 

lol

 

just like everyone's saying. get new bushings, new tie rods, you'll handle as good as, or better than any eg or ek.

 

Driven did you really use CD?



The rest of your post is spot on !
These cars just are not able to hold the ground like a true sports car, aerodynamics are... well too in-depth to try to cover in this forum but these cars just don't stick like something made to at higher speeds.

This is super dumbed down but they are slippery at some speeds not at others high speeds are not these cars friends.

I've tried a few things to help to no avail yet.

 

I don't believe Honda designed these cars to see triple digits all that much, it's not like they have an Autobahn in japan.

regarding the OP, there is some truth to it. Mainly because the EG/EK are newer cars.

 

It's definitely scary going 130+ in the CRX but I know what you mean by saying it's scary at triple digit speeds. My Suspension Technique rear sway bar made a huge difference in cornering & hwy speed stability, some nice coilovers will help too of course, & also VERY important is your alignment. When your toe is out of whack then it will be very unpredictable. Haven't replaced any suspension bushings yet & it's pretty decent at higher speeds.

 

super bump!

great info's for noob like me :D

 

Hahaha, I did... only cause of the speeds that the poster was speaking of...

but, yeah, either way...

the main thing that's going to affect how well a car handles (assuming everything is properly maintained) at various is [all at once everyone]... Alignment.

 

I'll let you slide this time <3

Yes alignment matters a ton esp on cars like this at speed.

My z06 ... is like a rock at 140+ ... so I've been told >_>

 

i have some cheap *** skunk 2 coilovers and springs when when ive gone 135+ the car was just fine....

 

Some people recommend getting a camber kit after lowering their cars since your camber is thrown out of whack. I just got an alignment to fix the toe (which pulled to the right really bad) on my 91 crx si. It also has tokico blues, and skunk2 coilovers, they helped a lot at high freeway speeds.

 

I wouldnt even think of hitting those speeds if your still rocking the original trailing arm bushings. Considering how bad mine were 6 or 7 years ago it would matter what your rear toe was set too. This just goes along with the car needing proper maintenance.

 

i think a crx handles decent at high speeds, considering its very light. but i also think they handle alot better with smaller tires versus bigger ones. i had 15's on my rex, i went to 17's and it felt like i wore boots to run track.

 

doing 130+ on EF, standard set up, sports suspension & lowered, no handling problem.
its just the car seems to be doing very well during high speed, probably the down force & suspension plays the main role here.

 

I understand going triple digits with such a car as my last 5th gen prelude, because they were stiffer on the road. But with a ef, ill keep it under 100mph. Invest alot of money into the suspention and extend those wheel bases
