I've already got that damper sitting on a scratch build. It's not the shock, but it seems better than the all plastic damper tube would be.
Carbon fibre front suspension is definitely interesting, though ride height will still be tough for carpet by the looks of it. For asphalt racing no hassle, and given they do more of that in Japan, Tamiya may not worry about it. So, the upside there is that machining the bottom of the graphite arms should produce better results than doing the same with the plastic ones.
I've found the flex in the front suspension to be a useful tuning tool. You actually get a little camber gain through the corners because of the flex in the plastic. Putting a strut across the front takes away the extra steering that generates. I'm guessing the graphite arms will be somewhere between those two extremes.
Has anyone got a close look at those ride height adjusters yet? I'm curious to find out if they have some slope to them. I'm thinking there might be an ability to fine tune camber/caster by turning them through 90 degrees.

It look very nice, but just like typical Tamiya fashion they always want you to buy a few option parts even with their best chassis kits. I would have included two aluminum servo mounts with the kit not the plastic ones.

im afraid to ask what it will cost

Looks sweet. Too bad for the price you'll be able to buy 3 or 4 AE R5

Just compare and contrast to the RM-01X.
There are a couple of things that aren't in that article though:
*Graphite composite arms
*Front ride height adjusters
*Graphite axle
*different damper
And not everything in the article is in the "X", e.g. titanium nitride king pins, steering knuckles.

@RedBullFiXX: I noticed from pictures that you've posted that you have the ackerman set up to have the steering linkages further forward in the car at the servo than at the steering knuckles. Other pictures I've seen of the RM-01 floating around on the net have the links more perpendicular to the centre line of the chassis. Is this something you've played around with? If so, why did you decide on that configuration?

Test to see what you like for your style, car, and track conditions
This is a fine tuning adjustment
The more perpendicular, is normally more steering response

Here are a few of pictures on my RM-01's. I hopped up the one I bought and made another one from the spares. I do not race so it is just a fun car running on two cell lipo at the moment with a 10.5 t xerun motor with a 22t pinion with the stock spur. The other has a 13t ezrun motor with a 20t spur at the moment.
