The longer pistons is not a correction or a band aid.. it was a necessary part just like the TC suspensions mounts.
Also they already designed special type of arms and suspension mounts for the Normal XV01. They also have 3 different types of arms for the TC: 416/417 reversible, 418, & 419x... which all can be used on the XV01 if you use the TC suspension arms and longer front pistons. These arms all have race proven geometry.
It would also be costly to make a special set of arms just for the XV01 TC... given that it’s a cross over chassis, most likely on a limited run.

I wasn't saying they should make special A-arms just for the XV-01TC. Do either the 418 or 419 arms fit without needing longer shock shafts?
I disagree about the longer shock shafts not being a band-aid. The front shocks on the XV-01TC are slanted front-to-rear as well, so there are two different ways they don't fit quite right. If these weren't problems, Tamiya wouldn't have spent the time and money to design a different front shock tower for the FF-04 Evo. As I'm sure you know, the FF-04 Evo shares all of its significant front-end parts with the XV-01 -- except for the front shock tower and the special slightly-longer front shock shafts. Tamiya could've, and I think should've, carried over that special front shock tower to the re-release of the XV-01TC.
That being said, I do appreciate that Tamiya made those special slightly-longer shock shafts, because they have enabled me to fit all 5 of my HPI Nitro RS4s with TRF shocks.

Nope.. shock holes vary between the 418 and 419x. 419x arms were designed to use with 05G blocks which are very wide for carpet racing.. wide front aides in making the car more calm on high grip surfaces.
Back to XV01. Most of us run the car with the standard arms and the long shock ends. If you set up the car with the shorter shock end, you will notice that front ride height with the standard shock pistons is actually very limited. If memory serves me well, you can barely reach 5mm. So in part the longer pistons that come with the TC version are to address this. M06 for instance also uses longer pistons in the back for reaching proper clearance.
As for the shock angle.. the wider TC style arms allow the shocks to be more laid down in front which aides in TC racing, especially with a car that has so much front weight bias... so again the longer pistons offer an advantage.
As for the shock angle from front to back.. you adjust that with spacers.... tamiya even has a specific one for shocks. My 419x uses 1mm in back and if I run a shorter wheelbase, I have to go up to 2 mm.
If the FF EVo 4 does have a different front tower . I’m sure you can opt for that part for the XV.
Anyhow, as Qatmix mentioned .. this is a rerelease with no changes as Tamiya is known to do

Hi There, my XV-01 carbon chassis is made by a small RC parts development workshop in Hong Kong. All their stuff just made with very small volume, and this xv01 carbon chassis is no exception. I believe i bought their the last 1 at the end of 2014 on the HK rc forum, and it was the only place they sell that stuff.
You may find a bit more detail at for sale section.

My xv-01tc-rally was pretty amazing albeit very modified to increase droop. Lots of things were shaved. The longer arms and wider stance helped much to make the car settled. But I have found the long damper spec towers with big bore shocks on stock suspension to be more beneficial and durable than my TC rally setup. For me that whole conversation process was a very good learning experience to understand suspension geometries and all the wonderful interchangeable parts that Tamiya gives us to experiment with.
I still run my xv-01. Like most of you I am sure we all still enjoy it.
The idea of the xv-01tc pro being rereleased is cool. I know when I was looking for a chassis to start rc'ing again I had my eye on that one, though it was already discontinued.
This chassis is still my go-to for multi surface bashing.
