I have standard Savage X lower arms, and my IRC shocks are mounted to them using the mounting blocks included in the fitting kit, and I've not experienced this problem.
You seem to be over thinking it. It's simply a universal servo saver that replaces the stock one. Not necessarily only for Tamiya. Whether it's an 'upgrade' depends entirely on the quality of your original servo saver.
My Savage is a heavy old beast and I bash it hard. I've never broken a single shock tower. That said, I have braced my shock towers using Hyper 7 upper suspension arms going from the top of the towers to the TVPs.
I agree on the Alza bulkhead braces though. Essential upgrade of you're going to bash your Savage anything like 'enthusiastically'.
Looks great, but as mentioned it looks a little 'off' because it's not 100% true to scale.
Loved my 110 but couldn't justify owning it anymore as I was constantly fixing it and it was a daily driver. Turned to the dark side now and have a Shogun....
It's the battery tray from my Hyper, it's from a Hyper 7 conversion kit, the make of which escapes me know... It's mounted by being bolted to an aluminium plate that passes underneath the modified radio box.
Why? Because he has a hobby? I'm pretty sure you're on these forums because you've got an R/C hobby, so why is this guy any different?
Sure, it's pretty extreme, but why be so judgemental?
I've run my Savage with them in the past, here it is with a Slash shell:
And here it is with a Blitz shell:
They did require a lot of trimming to clear the wheels. I love the look, but they are a pain when jumping due to parachuting.
