imo buy a carbon chassis conversion kit for your ta07R, the car is already very capable and has the essential parts to go fast and more. I don't see what you would find in the TRF419 that the TA07 doesn't already have.

Try running the mid motor layout on your ta07 and see if you like it. It's not exactly the same as other others, but mid mounted motors are back in fashion

No Carbon conversion needed with the ta07r.

I would try the low shock towers and smaller shocks.
For me it really improved my laptimes,and for other drivers on our track with an ta07 it was the same.

I run the black Exotek ones for an year now,no problems at all with bending ect with it and it has survived critical hits too
Also it really reduces the slop a lot also,for me a must buy.I would indeed wish that tamiya creates alu ones,or even better durable pllastic ones

07 is a very capable platform. As you mentioned you already have a 07R. Why not use it as a base to learn about driving and setup? I have been on the same route before and owned a TA06 Pro, TB04, M05 yet still have to sell them all because they are actually not needed to learn how to race. Eventually I ended up with a 07 pro which helped me break the 15 second barrier at tamiya track....
419 should be a very capable chassis but it is not a good idea to start running on the track thanks to the parts availability nor it is good for bashing as the carbon deck is prone to scratching. Worse thing still is the parts availability especially in the chassis specific parts. The original 419, though has all its carbon fiber parts in 5 digit spare parts system, takes me half a year to get all of the carbon fiber parts. The last thing I bet any driver want to do is to wait for a lower deck to replace the broken one.

with the idea of the plastic pulleys having give I assume you mean in mod? or do you feel its happening with stock (21.5) on black carpet?
How much weight did the alloy rear diff add? I have never really had any leaking issues with mine but the idea it will keep the temp down and the feel more consistently the same during a run would be a bonus.

Is anyone here going to the iic race?

Is anyone switching out the ball cups? if so did you change the ball studs to do it? also if you switched either what brand did you switch to.

I switched to associated ball cups and studs but they seem to wear out very fast. I only switched to have a hole in the ball cup I know Tamiya made some now but I assume some people have found a choice that works already

If they are 4.8mm ball studs go with the Yokomo BD8/BD9 open end cups. If they are smaller use the older BD7 cups, they fit really well and have the hole for the driver.

Yep. Switched all my newer cars to the new Tamiya ones.
Tamiya #54868 and #54869.
Studs I use kit ones or Tamiya #54208, 54209 and 54648.

Bombproof!

I'm sceptical...






They are now available to buy, but I'm not convinced to replace all my old ones with these.
I think, these will only slowly prevail with the next generation of vehicles.
No axle balls anymore, therefore pivot is now 100% the suspension arm itself...

These are great. You'll be able to narrow the rear and tune the roll center like you can't with the old mounts that only go down to 5.5mm 5mm (sorry). Don't discount how much of an effect these can have.
