Hi,

I have EG civic and I have just got new suspension...
So far I have f/r strut bars and ITR sway bars...

But I have this feeling, when driving on twisty roads, that the chasis seems to be flexing... I'm not to sure how to describe it, but I can also hear this sound like metal flexing...

What can I do to stop this flex and noise without going over board eg roll cage....

as many bars as possible

B Pillar Bar
C Pillar Bar
Trunk Bar
Floor Bar
Fender Brace

thats all I can think of now...

a little flex isnt such a bad thing.

and trev your right about all those bars, but by the time you've finished buying all of them, you could of had a welded, painted cage

yeah, I know. But if you want something that is easy to remove, the bars are easier. Just simply bolt on.

Do-luck makes some quality stiffness adjustable bars

start with a front and rear upper strut brace. Then , if not stiff enough venture into lower trailing bars etc and b/c pillar bars etc.

Or maybe jkust get a larger rear swaybar and make that suspension work harder instead of worryign of "body flex" :)

Does anyone have any pictures of a floor bar or a fender brace?
I can't quite picture where they go in my head.

Or go hardcore, strip the car to bare metal chassis and spot weld for extra rigidity...

The fender braces go under the front fenders. And the floor bar goes along the floor behind the front seats (where the back seat passengers feet go)

Ive seen those fender braces... how effective do you think they are?

Can't imagine they would do heaps, but I am sure you will be able to feel a bit of difference. Coz the front is already fairly stiff. But I am getting some anyways sometime soonish, once I have sorted out a few other things :D

if you really want a stiff chassis, go get some rollcage..
i have front and rear strutbar, floorbar, b-pillar, custom trunkbar, and swaybars but i still dont find it stiff enough..lol
or if you dont want rollcage, add a z-bar that connects to you c-pillar-rearstrutbar and trunkbar.. (emracing or memoryfab make them)

I think you should do it in this order:

1) Front Strut
2) Rear Strut
3) Rear Swaybar
4) C Pillar Bar
5) Front Swaybar
6) B Pillar Bar
7) Floor Bar
8) Fender Brace

But it all depends on convenience. The only reason I put C pillar before B pillar is because it doesn't effect people trying to get into the rear seats.

we've been talking on the california sol board about the possiblity of using an expanding foam injected into the frame rails on our cars. This is a rather common modification among the old ford mustang owners... basically consists for using a two part expanding foam thats meant for chasis reinforcement being applied into the hollow frame rails, reinforcing them from flex. On the del sol's especially, the flex that causes the problems is from the front to the back of the car, not side to side, so all of these pillar bars, floor braces, etc are worthless


also, keep in mind adding braces isn't necessarily better. I ran at a test and tune day at the track(autox, not drag) and was consistently running about a second and a half faster WITHOUT a rear strut tower bar than with it in.

I would personally do it in this order (based on most effective first)




Rear Swaybar with tiebar
Rear Strut (if hatch, otherwise swap with #3)
Front Strut
Front Swaybar
C Pillar Bar
B Pillar Bar
Floor Bar
Fender Brace

With regards to the foam how durable is it? I have read that after a period of time more foam needs to be injected as it shrinks.

there is foam designed specifically for injecting into a chasis for this purpose. I haven't ever heard anything about it shrinking, in fact the way it works, I really don't think you could even inject more foam if you wanted to.

you are running a rear ITR swaybar?? are you sure the sound you are hearing isn't the bar ripping your subframe??

hmmm to counteract that - you should invest in a trunk bar and C pillar bar.

see, I disagree... the proper way to counteract the subframe tearing out is by properly reinforcing it

2) Rear Strut
3) Rear Swaybar
4) Front Swaybar

i'd also like to know this, but for a civic. Am i going to notice a difference if i changed to something like a cusco brace (thicker/larger). Or is it advisable just to stick with the standard brace?
