There are alloy versions of upper arms to be had at any online site. Tower bars come in many colors and camber/caster options.

As for the pink clear chassis it is a bit involved to swap electronics from one chassis to another but you can find just the chassis tub online...find the one labeled "SP" for a bit tougher plastic.;)

I'd just get an aluminum upper (and maybe lower too?) tower. I remember way back when I was racing my 1st 015 and demolished the left upper arm.

You mean the suspension arm on the chassis?
Yes they brake easily. Gat an alu bar instead. Breaking a second chassis will be more expensive then buying the alu bar.
There is no need to buy the lower bar, I never seen a car in my club break the lower arms. Only the upper.

+1 on this, just replace the upper one with aluminum. I like the 1 caster ones myself.

Depending on your driving style, there is a considerable difference in how the car feels with an alloy upper tower than with the stock plastic arms. On an Mr02, I prefer the stock plastic towers. But I have had good results with replacing them in alloy. The stock feels a little more responsive due to less mass high/forward.

Camber/camber can also be adjusted with the towers. I would stay with 0-.5d caster, more than that and you may go pretty far away from where the car was on setup... Caster will give you a little less initial steering, with more exit steering and will track straighter on the straights. For high speed tracks, a little more caster works better. Tracks with many tight corners, less caster works better.

If you have no issues in the electronics, I would also suggest getting the stock chassis with the "SP" because the plastic is more durable and does break easily.

But if you have doubts about the transplant, go with the hop-up options with aluminum conversion of the tower.
