Cheers Simon (and everyone else!), definitely food for thought...
Steve, I ran Simon's set up exactly from the Scheuy website on Sunday and it transformed the car. Adding weight I think made the biggest difference, especially between the batteries and motor, plus going to the five degree rear strap calmed it down out of the corners. It definitely felt more planted than it has in the past. Tyre-wise I had silver cut staggers on the front and BB greens on the back and the balance was spot on... I'd not used the 5 degree blocks on the front before, and had found the silvers really grabby and inconsistent. On Sunday I put the blocks in and they were definitely the tyre for me.
Hoping to make it down Sunday if I can find a lift (still no driving big cars

), if I do I'm going to back-to-back the car with long and short Grippas I think, to get a feel for it - carrying more corner-speed will definitely help as I feel that's where I'm loosing time at the moment. I'm also trying the shocks with cut-bladders to see what they're like (mainly 'cause I split a bladder and I've been too busy to order a new set

). Hopefully see you there mate.
