I am gonna put some upgrades on my HPI RS4 EVO 3. But I am alittle confused about what to get. I am gonna upgrade to new shock towers, upper chassis deck. But I have a choice between: Woven Graphite, Carbon Fiber, or aluminum. Which is better? The price is pretty close for the graphite and carbon, the graphite being a HPI product and the Carbon part is made by Hot Bodies and the aluminum is HPI and the cheapest(!?!!?). I also want to get the upgraded chassis for it, the HPI one is 59.99 and 3mm thick and a Hot bodies which looks the same is 19.99, but I dont know how thick. Any help would be great.
