Powerflex bushes - make a big difference?

[Esempe]

Just fitted KW variant 3s & about to fit some h&r anti roll bars to finish the set up - wondered if it's worth getting a full set of powerfelx bushes?

Do they make a big difference - are they good for the road or too stiff?

Desired result is to have the best fast road set up with some track use.

Thanks people

It makes a difference,

Just be aware that eventually you can make these probably a bit too harsh for most peoples expectaions of a normal useable road car.

You can see my spec below, and the majority of people 80%+ of people who get in it or drive it find it a bit too much, and thats considering that most my friends are die hard car nuts !! lol

I fitted them a 911....it ruined the ride as it was way too hash

Powerflex normal range ( not race black parts) are approx 30 % stiffer than normal bushes. the advantages apart from the life time guarantee are that steering geometry movements are also limited . This improves tyre wear on the front tyres particularly and for you more importantly improves track times and traction . ( not that an RS4 has a lack of traction) , movement in the control arm bushes causes changes to the steering geometry which will cause tow in or tow out when suspension is under stress . Any slight firmness felt will be a good trade off for the numerous benefits .

they make a bit of a difference in most cars i have owned
certain bushes do screw the car up for the road with increased nvh[noise vibration,harshness]-for instance rtabs on m3-gotta be o/e,cossie gearbox rubbers,diff mounts etc
never fitted any to the rs4 as yet[although renewed all front end arms with meyle hd] as for my road use it doesnt need it-i may try the front arb though
biggest difference i noticed was fitting purple polybushes to the front brake reaction arms on my old bmw x5 e53-far more positive on the road,no excessive wheel kickback etc-with zero negative effect
