The rear quarters in my 04 started to rust through (daily driving 250k tends to do that). OEM panels arn't available anymore and I didn't want to chop off rear quarters only to get unlucky and have them rust again so I tried Sigala's carbon fiber panels.
I was a bit nervous because it's $$$$ and there are minimal reviews of their products, but I'm happy I did.
Good communication; made in 3 weeks and a week shipping. Carbon weave looked great and the panels themselves were quality pieces (straight, plenty of return area to bond into the car, mounting points marked, etc.).
Body shop said they were basically bolt on and lined up perfectly - no bondo/fiberglassing/etc. needed - so the molds they used are good.
I also replaced my doors and front fenders while I was at it - doors came off a donor and front fenders were new OEM (still available for $200) - and according to the shop the rear quarters were easier to install than the OEM pieces.
So yea, if you need panels for your 03/04, I wouldn't hesitate to buy Sigala parts.
nb: I painted the panels my body color (silver) so they arrived uncleared which is why they don't look glossy in the pictures.
