i ran the prototype today with a 10x1.the car was very good.very easy to drive and very predictable.i will need to try a little more set up on it to get a slight bit more steering out of it being that it is a 2.25mm chassis plate.this roll center change may have planted the rear too much.if i can get a little more steering for the tight sections,it will be perfect.this will make it a do all surface chassis kit.it seemed to only push slightly in 1 turn coming off a high speed sweeper.the turn is very tight.i may be being picky but i want perfection.im about 99% with the new car.i know exactly what i want to do to fix this also.i should have it ready for production shortly.3-4 weeks tops.overall i am very happy so far.it ran well enough for a TQ and win today.
