I believe TQRCRACING has the parts.

Is the TRF101 going to be legal for TCS races next year?

I have upper arms in stock, but the other parts are hard to come by.
I have a full kit in stock, might have 2 if there are more coming to me

I have a F104v2, i widened the rear links myself. Is the front end of the TRF101 an upgrade for my chassis?

I will be racing on a medium grip carpet, and outside on medium grip asphalt.

Has this been asked yet? i haven't read past page 2 of the thread...

Its not really what I would call an upgrade, it was designed mostly around the 101 chassis but it will fit on your 104. It is a little harder to get the front ride height where you want it if you plan to go 4mm or lower in ride height. Tuning Haus has a shim kit for it that helps alot but I have found the front end generates a lot of understeer. I went to the exotech front end and have been very happy with that.

I've used the exotek on the front of my TRF 101 and it was night and day. The exotek is easier to adjust for ride height and camber adjustments etc can be done very quickly.

So you guys are saying the solid top arm, with the spring on top of the knuckle is not more stable? I have a "home made" exotek type front arm setup like this
http://www.tqrcracing.com/shop/produ....asp?p_id=2543

This is my best bet?
For medium grip asphalt

Anyone have a pic of their exotek front on a 101?

How am I supposed to get 3.5 to 4 mm ride height in the front?

I decided to take the TRF101 for a spin. I built one off the shelf to see how I can best share the differences between both platforms.
As most of you may know I have A LOT of time on the V2. About 6 weeks ago I was in Japan talking to the designer of the car. In case anyone wondered it's Kiyo Suzuki. He's the same fellow that travels the world with Marc Rheinard developing the TRF touring cars. The man knows his stuff when designing cars in case you wondered.
In short Kiyo and Satoshi Maezumi told me the new front end changes the way the front end responds to your steering input. Basically, you'll notice it feels more neutral compared to the standard front end. Having driven a million laps with my V2 around the Tamiya track I can confirm that is indeed the case. The V2 is a stable car. However, the 180 hairpin turn after the sweeper has always frustrated me as the V2 wants to continue to turn. You have to be careful after the 180 to keep the car straight to make the inner sweeper. In the past I've tried to fix this with dual rate on the radio and with tire choice and sauce application tricks. With the TRF101 the car enters the turn with immense stability and there is no sign of the car wanting to continue to turn after applying throttle after the 180. It's just that stable. I believe this is the case because you now have a solid front end like the F103 on top of having the side links further apart. With the F104 link front end you have more movement going on with the front end, which makes for some unwanted movement. I didn't think this was an issue before, but it seems like the solid front end cures sensitivity and over-steering. Also, loosening the front screws on the carbon mellows the car out even more. If you think the front carbon piece doesn't move if you loosen it think again. There's a ton of movement. It's a great tuning option. I would suggest making sure the whole is big enough so the screw moves freely with the carbon top piece. Also, Kiyo informed me that I should experiment with using O-rings instead of the steel washers in the middle of the front end. This will make for a softer and dampened front end.
In short...I put two packs throw the car with my V2 starting point set up. It can only get better once I begin to play with more things. For one, the stock instructions have the TRF shock built with too much droop. Surprisingly, the car remained stable at the Tamiya "Kink" even with that much pod droop. Typically, you have to set the V2 with little pod droop to keep the car stable though the kink. Not so with the 101 so it seems, but more testing is needed.
So... the front end is not better than the Exotek setup? or better?

It's different. The TRF101 front end is more stable as it won't dive into the corner like the F104 front end can do. The F104 front end does have the advantage that you can adjust roll centre, and with the Exotek upper arm you can also adjust caster and camber. With the TRF101 front end you can only make one adjustment for camber and adjust the flex of the upper arm

Sorry to ask.... but I just pulled this from Tamiya usa page.

1.Legal chassis platform: F104 Version I&II and F104W. The new TRF101 F1 chassis is in an incubation period and will not be allowed for use in TCS racing until further notice.

Do you know anywhere this is officially updated?
We have a TCS race in March.

Best to contact Fred Medel if there have been updates on TRF101 legality at TCS. Last I heard it was not allowed since the TRF101 is a limited edition car.
