Well, I've searched the forum but can't get a clear answer.

Looking at getting sways but is either one better than the other?!?! I know the H&R are beefier.

Also for my C2, I read it's not a direct fitment like the H&R sways..... What's needed to make the RS sways to work.

TIA,
John

 

also interested in more information!

Had read before that it was suggested to go for RS sways over the H&R... but don't know if that's also the same for cup sways...

 

Changed the title and my text to RS swaybars and not Cup swaybars.

That Is what I meant to say.

Sorry for the confusion

 

Cup and RS are the same, 24 mm front and 18 rear. Front is adjustable in 5 settings and rear in 3. I think the RS/cup sways is better for a C2 to reduce oversteer and get more rear traction. The H&R are 24 front and 26 in the rear and is probably better for a C4 were you want ot reduce understeer. On a C2 it doesn't sound right to me and I think Porsche did some thinking about this.

With that said, a lot fo people are happy with the H&R sways, so as often it is a question of religion. The Porsche sways are also more expensive.

You need to replace the sway bushings since the sways are thicker. In the front you need the RS Drop links. In the rear I suggest you replace the (now by age sloppy) droplinks with new one's or even better, the solid cup replicas from Rennline.

Oh good thread.

 

My decision making process was that the RS bars had been designed to work with the much stiffer springs on the RS and therefore were not necessarily a direct bolt on solution for a softer sprung C2. Hence I went for the H&R bars. My experience is that they significantly reduce the roll compared to my previous standard bars. Very happy with what they have done.

 

This.

FWIW, I use the H&R bars and have felt no need to change.

 

had both. Now, i`ve H&R in front and RS in the rear. With the quite stiff RS-Springs & H&R sway in the rear, my C4 oversteered..

With proper track focused spring-setup, RS is the way to go. To "improve" a too soft spring-setting and make a C4 feel more agil, H&R sway are usable...

For a C4: on the front, you can`t use all the whole adjustment range of the rs-sway, so you could save the money for the RS in the front and use the cheaper H&R sway (24 instead of 25mm).

 

Correct me if I am wrong, but the way I see it, a sway bar should be designated by its torsional strength rather than diameter. Is there a way to obtain that information from the manufacture, would be interesting to see.

 

On my C2 with PSS10s I felt the RS bars to be too stuck at the back, resulting in understeer, so I changed the rear one with a 26 H&R and now the car feels much more alive and neutral.

 

Koenig Roland,

Front RS and H&R sway bars are both 24. The only difference is that RS is 5-point adjustable, where H&R is 3-point.

 

Anto, H&R is only 2 position adjustable

Also on a C4 you need to run it at the harder setting to avoid rubbing on the front driveshafts

They are a massive upgrade on the standard set

 

I thought a known, proven sensible (and cheap) upgrade for C2 handling was to leave the front stock and change the rear to a ARB from an early C4 (smaller). ?

 

Tdiquattro: The stock sways for both C2&4 is 20 mm, front and rear. Except for C2 MY90 that had a 21 mm rear bar. So a cheap first step for a C4 is to mount this 21 mm in the rear to achive little more oversteer.

 

Thomas, stock rear bar on a C4 is 18 mm which is why they upgrade to the C2 spec to reduce understeer.
