Seems like he switched to tamiya big bore M shocks this time?

The Tamiya c-hubs are fine. Marc just needs to focus on hitting less stuff and they won't break.

Yeah but it happens. And if one mistake is going to put you out of the race that's no good. Not just the weakness but also the amount of play in all directions.

Did Marc use the TRF420 prototype as Akio Sobue did?

Seems like a TRF420 Prototype. The shocks are completely redesigned.

Do you guys CA prep the shock towers? Or is it unnecessary?

Seems like the prototype is still unstable in very high traction condition. I always felt my tamiya cars are a little too aggressive for carpet and it seems to be the case with Marc as well this time.

Anyone know if they used aluminum chassis or carbon?

Did you watch ETS round 1? His car was dialled. This round they had 2 mins of practice only before qualifying, I don't think you should read too much into it.

The TRF car are made for winning IFMAR championships which are held on outdoor asphalt tracks and have the chassis flex for that purpose.

That said, I had some progress this week actually following the setup sheet
for the Carpet Setup by Qatmix "TheRCRacer" with the exception of Simmi's recommendation of completely removing the suspension block shims both front and rear and using 1F rear suspension block. I was about 0.8 to 1.0 seconds off the pace all year it seems from the best 1 or 2 drivers fast lap stamp and with both setup and the Fantom motor just put in place of the LRP X12 even though I geared down 2 teeth thinking that would be the way to go to get away from others charging me down, I was able to get in the 0.6 to 0.8 range back on fast lap to fast lap comparison.

So FDR is now at 4.33 but I need to get into the 3.8 range. I had 3 of the fast guys try my car out and it is topping out too early and definitely one of them also feeling what I see as my car is wasting time settling the suspension before getting on the gas again. So mid corner and exiting, car still unsettled and speed not the greatest.

My setup sheet from Sunday:

Other items on the horizon to try:

Mazda Speed 6 Body
Stiffer Springs move up 1 level on front and back
Sorex 32 Tires
Thicken up the Diff Oil to 4000, not sure about 5000
Actually use my SkyRC Corner Weight Scales and Balance the car!

Low Profile Shock Towers set
Yokomo SLF Short Shocks II Set with all the upgrade in Shaft, Oring and Bladders
Yeah Racing Aluminum C Hubs 4 Degree as these Plastic TA05 ones are flexy
(at 12USD a set, I can stock up on these and build a jig to measure the angles to check for a bend. I will also install Xray Hard Bumper and Square RC Front Wide Resin Suspension Guard to protect the suspension more)

If ETS carpet provided very high traction, I doubt most drivers would be using LTCR bodies ?
