Minimini, all updates are indeed posted in the topic K-Brewer posted - from Page 13 onward are all updates and discussions on the current car.
In summary, the car is working quite well, but it's performance has to increase to become production ready. The project is a lot of fun and I'll continue development - whether I can make it as quick as a production car is not clear yet, but my ambitions are to make an FWD (conversion) kit... one that leaves the RWDs biting dust of course!
