Hello, i have kyb shocks and eibach prokit springs for base model and i was wondering if either of them would fit on SH model?

Shakes

believe the front is different. do a search.

The front is different, but as long as you replace springs & shocks simultaneously, it will work fine.

mugen-man

so, springs are the same for both models but the shocks are difference?

There are actually quite a few differences between the base and the Type SH suspension, The springs are not the same. The type SH springs are a little taller. The struts are different as well, the base where the spring is perched sits lower on the Type SH, hence the taller spring. It results in a little firmer spring rate than the base. Lets not forget to mention the front knuckles are different, the raius rods, the front trailing arms, and the roll bars are a couple of millimeters thicker than the base front and rear. In the rear the springs and struts are different on the SH, it has the same condition as the front where the perch that the spring sits on is slightly lower than the base model, and the spring is slightly taller than the base model, It is not as big of a difference between the SH and Base rears as the fronts are though, the rear trailing arms are a little thicker as well but not much. The only problems with aftermarket struts would be modifying the dust gaurds on the struts with stock springs, however if you go aftermarket springs and struts that are replaced in tandem you will not run into any issues..

So as long as you replace springs and struts on all four corners [B]together [B]then everything will work? Does that include any aftermarket spring and strut or only a specific brand?

pzpos360

sorry meant to take the bold off after "together"

Gerhard_001

Yes, eveything should be ok with aftermarket items. However you have to replace springs and struts (aftermarket ones) at the same time other wise you will have to make slight modifications.

so if i put eibach spring for an SH on an SS its bad? cuz i have that setup now and im not to happy with it

pzpos360

Are you speaking from experience? What is your setup?

I have a 1999 Honda Prelude SH that has been heavily modified and now has a built 600whp motor. I have changed every part on that car and can tell you base and SH prelude are two tottally different cars. Although the physical look of the car is the same, the mechanics of them are not. The SH has a unit called the ATTS, or Active Torque Transfer Unit. This unit is mounted under the front axel, and provides a slip differential between the 2 front wheels allowing it to handle better. Because of this units location everything in the car had to be modified from the base model to fit arround the unit. Therefore whenever you buy an item from an exhaust to a turbocharger kit, they are completely different. The SH model will only work with aftermarket coil overs, virtually no companies make shocks or struts for the type SH. The stock struts and coil overs are the best for the type SH. IF you manage to modify the struts from a base model to an SH, you will lose the special handling on the SH. As well every sensor will go off if you have not changed the computer to a complete engine managment system.

Yes I speak from experience, I have koni Yellows and eibach spirngs. They fit.

Please explain??

D, who has KYB's and GC coilovers and no ATTS light.

Also, I'm a little confused...the ATTS does not like wheelspin or high horsepower for that matter. When you say you have a 600hp motor built...Im assuming it is not in the car yet?? If it in fact is, that is why you would be throwing lights, not because you changed your struts.

skera

No im telling you experiences I had in the past. Obviously now since the AEM EMS runs my car i have no trouble with sensors.

600 whp SH ? i highly doubt it

so the S in ATTS stands for unit? you must be inhaling the unit.

yes, kyb's will fit... but not with stock springs. it'll fit with after-market ones. some springs require adapter rings to make the spring sit right.

you will get an ATTS light if your car height is uneven or if you slam it, dump it... whatever you call it.

skunk2lude01

I call bullshit until dyno, pics, or time slips are posted. If you have 600 whp in a lude, you will have one of the three.

skunk2lude01

It seems you have described lsd not atts, isnt atts when the back wheels activate outward or inward to compensate for the rear through low to mid speed turns?

pzpos360

No, ATTS is a LSD it is run off a seperate computer and various sensors that adjust wheel speed under different situations.

For the guy running the koni / eibach set up on his SH, did you have to do any modifying at all or did it just bolt right up in there?

bad-monkey

not that they're totally different, but i don't like calling ATTS a "LSD."

I agree. ATTS does not work when it detects wheel slip. Its always on... adjusting power transfer between the wheels depending on individual wheel speed, steering input, and other factors. Although you don't feel it working until you push the car hard.

Gerhard_001

No they just bolted on fine. The suspensions are different yes, but you only run into problems where you have to modfiy the struts if you have stock springs. Mine yellows bolted on fine with eibachs. As far as ATTS being an lsd, it is not. IT is classified as a yaw control. Here is a brief synapse of what ATTS is and what it does. under straight line acceleration the system operates like an open diff meaning that only one wheel will spin on a slick surface (eg.. like ice), also at the track it only spin one tire just like an open diff. There for ATTS is not an lsd. ATTS is located on the left axle, it is essentailly a smaller tranmission, it hydraulically activates gears in the unit to route the power.When you are traveling at speed and you corner there are senors measuring the cornering force, speed, and throttle input and can send as much as 80% torque to the outside wheel when cornering. There is a standalone unit that controls the ATTS unit itself, it is also connected to the ECU. So if there is any imminent danger to the ATTS it will tell the ECU to cut power.
