Think i may have been the only person to try the Atomic carbon Alu chassis so far as Danny Mcgee made his own.
So far i have found it to make the car more planted, the one i have is 80g heavier than std and obviously the weight is as low as it can get
, It gives me the feeling the car has more grip across the front and rear in slippy conditions even though there is no or very minimal flex.
I have not had a chance to run it on high grip astro but i expect it to be faster as it will keep the car incontact with the track more and make the suspension work a little harder
In a nut shell since running it i think i have got faster
