Upgrade rebalancing

Hi folks!

with the last update, a major rebalancing has been done to the parts upgrade requirements, which isn't quite mentioned in the update notes.

Previously, we had a huge need for conversion kits, which could be farmed in the car series races. For example, my BMW M4 Razor would have needed 25 conversion kits plus two materials to upgrade from epic to legendary. After the update, it's now 4 kits plus 10 materials.

Analysis

I've already done some analysis of this in the Tuner Trials post. Generally speaking, we've seen a rebalance away from repetitive farming towards more strategic gameplay.

Another quite interesting change has been put in - the garage storage is now fixed at 275 items, and can no longer be extended by paying gold (previously, we could by 5 storage for 30 gold). That removes quite a huge gold sink, and again, makes sense in the light of requiring a larger number of regular materials for upgrades.

Basically, this means you should no longer sell anything if you don't have to, as you'll need pretty much all materials at some point. And make sure you'll get the kits from the Tuner Trial dailies.
