I know Jeff is working 6 to 7 days a week through December, so maybe I can give you a preliminary thought, since I help him with the 1/12 car, until he has a chance to respond.
Basically, Jeff has not had a chance to drive the car with the kit front end yet. The first time he drove the 12x was 4 days prior to the beginning of the Cleveland race, having run another manufacturer's car for several years prior. The kit front end seems very interesting and elegant, but with practice time limited he elected to go with the WC front because of long experience with the AE style on carpet.
Maybe Jeff has some input from other Corally team drivers that he can share.
