H&R Anti Roll Bars

[Dekker]

Has anyone fitted H&R Anti Roll Bars to their cars?

If so with what type of springs and shocks?

As you might have guessed this is yet another upgrade I've done on mine! []

Suspension is KWV3.

You never stop improving Stevo... not you - the car I mean. Is the ashtray still original? []

Haven't changed it yet because it's not full. []

Suspension is KWV3.

Do they take much setting up Steve.

Also what I don't understand is that the C2 89-90 cars have 20mm Front & 18mm Rear
The RS's & Cups are 24mm Front and 18mm Rear
Whereas the H&R's are 24mm Front but 26mm Rear stiffer at the rear the opposite of the Porsches

Where to start!

H&R are not difficult to set up. Both are two way adjustable. Currently mine are both on the softer setting but still control the roll much better than standard C2 bars. Putting the rear on the stiffer setting would promote oversteer while putting the front on the stiffer setting would promote understeer. BTW changing the front bar is difficult to do without a lift because there's very little room to work with. I got Unit 11 to change/fit mine to save me the hassle and cursing.

C2 89-90 have 20 mm front and 21 mm rear bars (it's the C4 that has 20 mm front and 18 mm rear). Hence much less understeer on the C2.

RS bars are 3 way adjustable and have been matched by Porsche to the much stiffer suspension on the RS and cup.

The H&R bars have essentially been designed to stiffen up the street 964s which have softer suspension than the RS. KWV3 is stiffer than standard C2 suspension but not as stiff as an RS.

Thanks for the explanation Steve.

I have PSS10's on mine so I will do some more research as to what others have used.
I'm not sure how mine rates compared to the KW's. From the chart I've seen KW's have a lighter front spring but similar rears.

I know Walter Rohrl did alot of testing on PSS10 suspension which he waxed glowingly about as a vast improvement over the standard RS suspension which he said was too harsh.
