I've found my car much easier to drive with more weight up front. Not sure why I got the idea that there should be more at the front than rear, which is why I was asking. I do race on carpet so perhaps that's why I'm liking more weight up front and I'm still curious as to what weight distributions others are using

Parma T2 Bumper can be made to fit with very little effort. I make it fit on every car I own. It is the best!

Hello, first of all I am sorry to post a non-racing comment.
I am selling my Tamiya TRF 417, so if anyone is interested (question, condition etc...) please PM me.
PS: I'm based in the UK.

Thanks.

The team bring the weight of the car forward to give more steering (according to Jilles), which is why they often run 0.5 front 3.5 rear wheelbase. I've had mixed results with it, so lately I've been running 1mm/3mm to get more weight transfer mid corner to help the car rotate.

Speaking of wheelbase I'm surprised the team was running so short at the worlds. 0.5/3mm is the same wheelbase Marc ran at the Austrian EC when he won in '11 and that track was super technical compared to MACH. By comparison the setup Kiyo wrote down for me at TITC was 1mm longer, 0.5mm longer front and rear.

There is a very reputable seller on eBay that had the lower deck on sale for about $60. He said that the upper deck hasn't been released yet.

Hi , I have the first gen 417.

Exotek extra flex decks. Cut motor mount.

It is my VTR car(VTA over the states) , we have 17.5t x12 motors,blinky escīs 5.0fdr ,hpi vintage tires and 1425g min weight rules.

Now my question is how can I get this thing dialed on low/med grip asphalt(no additives allowed on tires).

It is easy to drive but not fast. It understeers badly, but if the track has even a tiny dust particle on the turns it oversteers...

I have tried with/without stabilizers,25wt oil to 50wt,(25wt rear/30wt front with red rear/yellow front springs works best so far).

5 front 5.5mm rear gc,5/4.5 droop has worked best so far.

1.5 camber all round and 2.5 toe out front, stock rear.

ball diff, the gear unit makes the car really tail happy.


So maybe you have some setup tips for me to try?


Also I would like to try the seperate sus.mounts, does these need any specific spacers? -or just regular 3mm shims/spacers?


Thanks ,

-Pate

Thanks, will try that.

shocks outer at the front arms, middle hole on the rear and on both towers.(found it is best like this when rest of the setups are like I wrote)

Just going through the car, it is in a million pieces atm, nothing too bad found, just worn pins on cvdīs.

I guess it(or some of the reason) could be the radio also, dont really like the dx3s that much. Trying to get m11x soon. (tried my friends m11 few months ago and got ~.3 sec of my lap times)
