I'll add my 2cents.... and will make this my 1st official post...

So today I became proud owner a '08 Alpine White 4.8i
(partial thanks to RH71, his setup sold me on the car and look)

my Cayenne S was a Victim of Hurricane Irene and it wasnt able to survive the 3ft of water it took in. RIP

ok now onto the post.

When i first got my Cayenne I decided to put 22" Turbo Replicas, they looked great, people loved them, truck drove awesome for a couple weeks, then the 60mph+ vibrations got worse and worse, no balancing could help it (i took them to 3 different shops) in the end i ended up with 2 broken rims and over a dozen bends..... this was running on a 35tire, already higher then the recommended 30tire, NJ roads are destructive.

(oh did I mention they weighted 50lbs+ each, gas mileage suffered, bad.)

Months Later fed up with the vibrations, I dropped down to New 20" Turbo II Wheels (also replicas) from oemwheelsplus / and put it down with a 45 thick tire, night and day, used them for months and they held up nice until the Hurricane ended it all.

Do I support replicas Wheels, Yes! just make sure you know the specs and know what you're dealing with. Regardless i do believe Factory Wheels are just made better and to higher standards, my stock porsche wheels were clearly example of that.

....this is why I waited until I found a 4.8 with the 20" Sport Package, so I would have to waste my time and $$$ on new shoes.
