They posted a collage of the scenes from the site set up in honour of the Fast & Furious star in California on Facebook.
"We've seen the most incredible outpouring of support from Paul Walker fans over the past week," the caption read for the post which has amassed nearly 800,000 'likes'.
"To those who have attended the many tributes worldwide, posted heartfelt messages online, and supported his charity Reach Out Worldwide -- we'd just like to say THANK YOU.
"Your gestures of love have meant so much. We promise to keep you updated via Paul's Facebook, Twitter, and Instagram, including on our plans for a global tribute. - Team PW"
During the unofficial memorial event, which was organised through social media sites, streams of souped-up sports cars were driven past the gathered crowds.
Fans left messages of condolence on a giant tribute banner near the crash site where Paul and his friend Roger Rodas died when the Porsche Roger was driving hit a tree and burst into flames.
Toy cars, candles, teddies, flowers and other tributes to the face of the film franchise were left at the memorial in the LA suburb.
The moving event concluded on Sunday evening with a drive through the area where the duo died.
The pair, who died on 30 November, had been attending a fundraiser organised by the actor's charity Reach Out Worldwide when they decided to take the sports car out for a spin.
The handsome actor leaves behind 15-year-old daughter Meadow and his long-term girlfriend Jasmine Pilchard-Gosnell who he had dated for seven years.
Paul shot to fame playing undercover agent Brian O'Connor in the Fast & Furious movies alongside Vin Diesel and Tyrese Gibson. They had recently started filming the seventh film of the Fast & Furious series.
