Wheel repair and pulley swap

Wheel repair and pulley swap
Gentlemen, I could use a little help.
First post here and I have done my homework by cruising the "frequently asked section" but couldn't find the answers to a few questions.
A few years back I purchase my wife a '05 XKR and she loved it. A few years later we sold our So Cal business and moved to N Idaho but not before selling the car. Big mistake we both miss driving it and so I'm back in the market trying to replace it. I have located a very low mile car that is almost perfect except that in less than 7000 miles the current owner has managed to scuff all four wheels. The damage is very minor so I'm not concerned about alignment issues but do want to fix them. My first question is are the stainless steel appearing 3/4 wide trim rings on the factory wheels replaceable? Besides the rings the wheels are perfect. My second question is about the super charger. Has anyone replace the stock pulley with a smaller diameter one? I have a Ford GT and on that Ford product () the pulley swap and computer re-flash is a safe, inexpensive and simple way to add some additional HP. I have a buddy with a Z8 that was about a length quicker than my old XKR and I'd like to correct that issue right from the start with this replacement XKR.
Thanks in advance, and nice forum!

Yes on both counts
Most remove the trims and get the rim polished or painted as the trims cost about $200 each plus fitting
Pulley conversions are very common, top pulleys cost $250ish (I'm in the UK so guessing a bit here, I can give our prices easy enough)
Bottom pulleys cost more and better to do IMO, however I do have both done on my XKR

Glad you found your answers..... If you get pulleys done, drive steady for about 500 miles, your ECU needs to recalibrate itself to the extra air coming in otherwise you will run lean and damage pistons, a bit like these...
This is what can happen if you do a load of mods and just go out and give it the biggun

Correct, these ECUs can self-adjust over a wide range, as has been well proven by our esteemed member Avos and his 100-200 HP Twin Screw KB supercharger upgrade.
The swap still provide some pretty good bang for the buck for light use where a cooldown period for the supercharger is possible. Improving the supercharger cooling can help further.
