If I were to upgrade mine, I’d follow 9x 19’s course. I don’t bash mine like crazy. More just ripping it around. I jump and wreck the crap out of it. But, it’s not off of ramps.
I’ve broken a front A arm on the right side, a drive shaft on the right rear, and a couple shocks on that same arm. Other than stripping a few pinion gears and the above damage, that’s all that’s been broke. I’m betting it’s got a hundred packs through it though.
What I’m getting at is the plastic Traxxas puts on their rigs is there for a reason. It doesn’t break very often.
I do plan on juicing mine up this winter with HD suspension parts like 8x 19 did, I just got too many other rc projects that keeps money going to them versus my rustler vxl.
It’s yours to do with what you want. But, it’s a great rc as it. If you can keep from hitting rocks and bulging tree stumps, breaking the lower A arm and bending the shock shafts, there isn’t much it needs. And, unless you just want to bling it out, aluminum parts certainly falls into the not needed category.
My advice woukd be If you like blinging rcs out, buy an ARRMA. Their bigger rcs usually have an aluminum chassis. And you can bling out shock towers, diff covers, chassis braces, etc…. It makes them a beautiful rc for sure. If you want tough and dependable, Traxxas has been doing that really good with their choice of plastic.
That’s my opinion. It’s just something to consider.
