Great thread, just wish I read here first. I have the ones from Best Racing (Poly) that came with some hardware but had issues with the holes not lining up. After a month of them being installed, its either due to the weather on Guam or my driving, but the part towards the rear started to sag and slowly pull away from the car. Now I'm in the market of getting the CF ones from either BaysonR or if Best Racing gets them in stock. None the less, its a replica and you get what you pay for so no worries.
