i have just received this kit for my XKR.
before, i had install normal version of Powerflex bushes. I think that it will be perfect in stock Jaguar XK8/R but is not good if you have performance pack ( 20" wheels, Brembo drilled brake system, lovered suspension ) like my car.

Now, i'm going to install this new BLACK SERIES...

Comments on the road test... coming soon

Wow, that kit is definitely going to stiffen it up.

 

I bought I set of these for my track XK about 3 years ago they didn't advertise them back then but I guess there is a bigger demand nowadays

 

Have you already installed black powerflex? What is your feedback?

I'm going to fit powerflex (black or standard purple) on 2000 XKR with 20'' BBS and I am not sure what to choose.

 

before i had install purple Powerflex bushes in my car but it was too much soft.
Now i have all BLACK SERIES powerflex bushes and the cat is perfect.

I suggest you install this kit with 20" wheels!

 

Wow.. wonder what the full set cost to the USA... man!

 

Powerflex black series ordered I wrote with XKR user from this clip: and I think black series bushes would be the better way to go.

One more thing: have you already fitted Ohlin's suspension kit from another thread? I plan to fit new, custom made suspension (springs and dampers) soon after installing bushes.

 

i had see this video but my car with purple bushes was too much soft.
i had install also eccentric bolts for camber and 15 mm wheel spacers.
I'm trying to fine-tune the settings and calibrations with regard to the new suspension and therefore still can not say exactly if they work perfectly.

 

if I can give you some advice the best modification I have done is install the limited slip differential QUAIFE QDF5W.

this is truly a precious object for holding and performance!

 

How do wheel spacers go with 20 BBS? Any interactions with wing margin?

 

H & R spacers 15mm. it is necessary to work the rear fender slightly by a coachbuilder because the tire could sometimes rub on this

 

these are 2 videos about the suspension front and rear panhard bar with the rubber POWERFLEX normal. You can see that they are very flexible and soft. Now with the black series is all much more rigid!
