TA05 ah TA05

I mostly play with co-workers at work during lunch.  We have about 8 guys playing at work (I got them into this ).  We form the track at the parking lot, and race about 30min almost everyday.  Other cars are: TT01, TB02, TA05, TC4, Losi xxx, HPI sprint2...etc.

My TA05 is pretty good in the group already, but want to make it better.  How much weight will I save by changing to the tamiya carbon chassis?  I saw AMAT's have carbon stays.  

No, I don't want to change car at this point.  Since I don't have time to go race, I won't invest on high-end cars.  But I may consider buying one more TA05

no.... here ah:
