I have been thinking about it KKITP are going - with a selection of Kei Kars (small Japanese Cars) check out this link http://www.kkitp.com/index.php/forums?view=topic&catid=16&id=18531
There is also another Japfest on 26 June at Rockingham See here http://www.kkitp.com/index.php/forums?view=topic&catid=16&id=18545
Yes there are 2 Japfests but I think the Silverstone one is the biggest. I look forward to seeing the KKITP Club Stand there
We went both Japfest events last year, Castle Coombe was the early one and also the best, the other was at Rockingham and was terrible (as you can see from all the negative feedback they received on FB), complete polar opposites to be honest. Just thought we'd give you the heads up anyway, and yes we are going to Silverstone but on a stand of a parts supplier and with our other car.
Thank you for the heads up. We have already bought our tickets and booked the hotel for Silverstone, so we won't be going to Rockingham. Look forward to seeing one or two Copens at Silverstone.
