Short carbon upper deck

Details:

1. 3 points fixing design (compared with last version’s 5 points fixing) provides more flexile to the chassis

2. More flexile chassis can improve the car stability at cornering in particular on low traction track

3. Flexile chassis benefits will be more easy to observe when the car is using Lexan body (as hard plastic body may hinder the chassis flex)

4. Highly recommended to use this option part together with our newly released wide bottom chassis plate
