It would be nice to see a T4R actually: Get some new people out there racing with a decent car. ECS front shafts in the box would be good as nearly everyone fits them to their car as it is and they cost a damn fortune to buy separately.
And how about bringing the packaging back up to an ultra high standard? The T1 came in the box with the bulkheads attached to the chassis so you would get a beautiful presentation upon the first time you open the box. There is a huge culture of "unboxing" out there now: It's one of the great joys of being a consumer.
