Rally suspension setup?

What do rally cars use for suspension? I would want a suspension setup that is very stiff but can take anything that is on the road.

I have Eibach Sportline springs with FFRP dampers but they feel too soft. They would bounce if I hit a pothole hard. There are a lot of potholes in DC.

I have a 06-07 Focus so please don't recommand 00-05 suspension unless you have some info on how to convert them to the previous models.

Maybe look into HotBits? Not too expensive, and it will be stronger, and be able to take the abuse. Not sure what options they have for an 06-07, but take a look.

A true really suspension will cost you $4,000 easy. The Rally spec foci use DMS coilovers that are something like $4500 IIRC.
Massive Speed system has a kit that allows you to use 00-05 suspension on the newer cars.
Besides the really pricey stuff there are not really any rally setups out there. Everything is lower and stiffer than stock instead of being same ride height or higher than stock with stiffer rates.

I am not exactly sure what you mean by "they would bounce if I hit a pothole hard"
But aside from going with a softer/ taller setup than the sportlines any change will merely make the ride worse over rough roads.

I mean the car bottoms out when it hits a pothole hard.

I don't want a soft suspension. It would just make the ride feel sloppier, worse handling, too much body roll, etc.

I want stiffer springs and dampers able to handle them and high enough for the road conditions.

I'm thinking maybe H&R coilovers since you can adjust the ride height. They make for 06-07. Does anybody have any experience with them?

If you are hitting potholes hard enough that your car bottoms out you need to start avoiding potholes.

If you hit those same potholes with a stiff suspension setup like HR coilovers etc, you will be on the short road to bent wheels and broken suspension components.

You might try a set of KYB AGX shocks and a stiffer slightly taller springs. The sportlines are known to be too soft for their ride height.
This would require the kit from massive though I think.

The wheels are already bent (sold them). I'm getting smaller wheels. I'm looking at EAP's.

I try to avoid potholes but sometimes it is unavoidable in some situations.

I'm trying to get some performance suspension ideal for the road conditions. I appreciate to read all your inputs.

I understand that. all about potholes not being avoidable sometimes.
You need to go with something maybe 1/2 inch higher and stiffer than the sportlines. That will help keep you from bottoming out and it will handle better. No what to use I am not sure. I don't think I would put $1000+ coilovers on a car that is going to see the hellacious roads that you have. I wouldn't want to risk bending them, as foci are somewhat prone to bending struts over extreme terrain.

You might look at 16" wheels as the added sidewall will be good for nasty roads. Also with a stiffer suspension the added sidewall will help keep the wheels intact.

There is quite a difference between H&R sport's and H&R touring. The sport is the original Cup Kit, which lowers a focus almost 2.5". the touring cup kit is a more mild drop (1.3-1.4 inches), and would be a more preferable kit to have for such driving.

If the H&R Coilovers are made for the late model Focus, that'd be the best route.
Another option is one of the coilover setups at www.batinc.net, used with the Massive adapter kit. You can choose Custom Spring Rates.
They aren't going to be quite as Durable as a TRUE "Rally" Setup, but they don't cost $4500+ either.

I respectfully disagree. After seeing, riding in, and driving Reza's car with the H&R Coilovers, there is nothing there that would make me want to go shagging potholes with it.

My question to the OP is, you want a rally suspension to deal with bad public roads? Or you just want a suspension that will deal with bad public roads that doesn't necessarily have to do with anything particularly rally oriented? Or are you actually planning on racing this car?

It seems like you just want a durable, sporty suspension for daily driving. :dunno:

I'm sure Reza's is Adjusted for Rather Smooth Surfaces.
I was trying to think of "Relatively Inexpensive" and "Durable", even if it may not be as compliant as a real "Rally" setup.
Honestly, to be Firm, And Durable, And truly "Pothole Flexible", you have to go to the "BIG Money" kits.
The spring rates don't need to be especially high... you just need dampers that are tuned for rough surfaces.

H&R Coilovers are out. I have the basic H&R coilovers right now with 21mm front bar and 22mm rear bar.

There is no way you could drive this car on anything other than flat roads.

I recomand stock springs with koni dampers.

Is that because of ride height, or spring rates?
Can't those be adjusted or selected to be appropriate?
:dunno:

His was at the highest setting and still way lower than my Apex springs. And extremely stiff, which out of the box couldn't be adjusted.

Any thoughts on the dynamic suspension? I hear they are the best for the Focus.
I'm not sure who said that...
:dunno:
Very Good? Yes.
As was said earlier, and in MANY threads, "There IS NO "Best"".
Anyone who throws the word "Best" around is either trying to sell you something, or they are undereducated on the topic.
If the Height and Firmness meet your needs, it's a good package.

as stated before, a rally suspension is extremely expensive. most of the time, the springs and dampers will extend into the body. allot of the coils are on the roll cage as it is more rigid than the wheel well and doesn't flex w/ the body. most of the setups I've seen for the focus are around 10k.
