With just over six weeks to go to the 40th anniversary celebrations at the Homecoming Scotland-backed Dunlop MSA British Touring Car Championship meeting at Knockhill Racing Circuit, Scotland's National Motor Sport Centre, in addition to the amazing event on August 23/24, which will feature four Scottish-based drivers, there are two very special additions to mark the year.Jim Clark 50th Anniversary Forth Road Bridge Parade - Thursday 21st August at 11amIt's the 50th anniversary of Jim Clark winning the BTCC title with Jim, John Cleland and Gordon Shedden being the only Scots to have won the title. To celebrate this, and the 50th anniversary of the Forth Road Bridge, Knockhill are working with the organisers of the Forth Bridge Festival (www.forthbridgesfestival.com) which will see a parade of six of Jim Clark's cars and four modern day BTCC cars across the Bridge at 11am.From 9.30am, the Jim Clark cars will be on show in the South car park together with the actual race cars of Gordon Shedden (Honda), Glynn Geddie (Toyota), Aiden Moffat (Chevrolet) and Dave Newsham (Ford) which will all be part of the parade at 11am. Members of the press and public are all invited, and the organisers have procured permission to get a photographer to the top of one of the bridge towers and to fly two drone helicopters to capture video and stills from the air too.There will be two of Jim Clark's single seaters, two Lotus Cortinas and two other early Jim Clark cars, all of which will then go to Knockhill and be paraded on both Saturday and Sunday of the BTCC meeting during the lunch breaks. Knockhill is working closely with the Jim Clark Trust to make this happen as the circuit is donating 20% of all sales (using the code JIMCLARK50 via advance online bookings) to the development of the Jim Clark Room in Duns.In a special commemoration, the crossing has been recognised as the first event to celebrate the 50th anniversary of the Forth Road Bridge itself, one of 11 special events over the subsequent month, culminating in a massive firework display. Homecoming Scotland 2014 Knockhill 40th Anniversary Marquee Knockhill are inviting back racers and their cars that have featured over the 40 years of racing at the Fife track through the help and backing of Homecoming Scotland 2014. The Homecoming-branded marquee will be 50 metres long, with 10 metres dedicated to each of the four decades of Knockhill's heritage and the final 10 metres set aside for the six Jim Clark cars.The display will be a tremendous throwback through time as each section will be customised to the relevant period with pictures and display panels from each decade, as well as playing archive footage on large screens within the marquee. It all adds up to a very special event, all kicking off at the Forth Road Bridge on Thursday 21st August and culminating with the usual three spectacular Dunlop MSA British Touring Car Championship races on Sunday 24th August.
