did you have to go to a lower king pin ball? Could you have gotten away with flattening the top of the ball end to make the wheel fit?

Finally had a chance last night to sit down and start working on my 415 for this weekend. I must admit that although the quality is typical Tamiya, (top shelf) the need to shim the diff & one-way between the bulkheads and the to shim the axles was very disappointing.

Question: I picked up the Optional Front A block like everyone mention. The Header card says that if you combine it with a certain part number it will decrease the width by 2.6mm and increase steering. Makes sense. But I believe the number on the card is for the A-1 front block?

I see that everyone on the internet is posting set-ups with the optional A-block and the D-1 block. Since the D-1 block in wider it sweeps the front suspension arms back. Perhaps its me but shouldn't the option A-block go with the A-1 block. Please advise.

Thanks

D/A blocks gives you toe out which in turn gives you more/aggressive steering.

In the front the D block and D Bridge Block is supposed to be zero toe and then you can adjust the toe in or toe out by changing the configurations.

Using the A Block and A Bridge Block will bring in the overall width of the front in narrower. Thard's excel spreadsheet has the block configurations charted out.

Thard TRF415 Website

After putting on the 2 A Blocks I had to adjust the steering turnbuckles to go back to zero toe as it makes the front have a lot of toe in when the arms and everything go inwards.

The excel sheet seems to indicate zero toe for 2 A Blocks. I don't know exactly.

I would have done this myself but using a lower kingpin messes with the roll center of the car.
I did shave the tops off of the ball cups and so far it has been perfect. I have hit walls hard enough to bend the aluminum turnbuckles but so far I have not had a ball cup pop off because i shaved the top.

If you are using rear sway-bars mounted in the stock location, you WILL need spacers or else the tires will run on the sway bar mounts. Also 28mm foams will rub on the lower shock cup (where the shock end mounts to the A-arm) if the shock is mounted on the outer most hole on the front A-Arms (during turns) without spacers

I run 28MM jaco tires all around and i do not narrow them.
I use 1.5mm of spacers on each wheel. this is all that is needed to prevent rubbing, with the exception of trimming a little off of the ball cup. An a stock car the 1.5 mm worth of spacers will make the car wider than 190mm however. If you are worried about being race legal, in the front use the A/D or the A/C block combo and you will be between 188mm and 189mm.
