Hi all,
I am currently working on a restoration of my 2001 Jaguar XKR coupe. So far it is going very well, and I've recently been looking around for performance options. Mainly the upgraded polyurethane bushings, sway bar, and supercharger pulley. I recently stumbled upon a website called Panthera Performance...and the prices are almost too good to be true! Does anyone have experience with this company? I am hesitant as I have never heard of them before... Website link HERE.
Many thanks!

 

I might order the bushings and see what happens...

 

if you're going to order bushings - why not just order straight from Powerflex

 

Capitalism at its best!
Check out the price difference between powerflex/usa and powerflex(uk).

WOW THE PRICE DIFFERENCE INDEED. Powerflex UK won't let me purchase from them, however the pricing matched up with Panthera who ships worldwide. $140 vs $40 is crazy. I've looked into it further and I have been able to find the same prices on several different sites, which leads me to believe Panthera is a legit dropshipper. However, we will find out soon! Ordering one bushing and seeing if it actually shows up

 

If you swap out the crank pulley with a larger pulley (need a machine shop) the supercharger will make more boost than a smaller supercharger pulley. Some people run both, but CA being 91 octane might not allow for that high of a boost level.
