The blocks go (from widest to narrowest)

1E, 1D, 1C, 1B, 1A, 1X, XA, XB, XC, XD

and there is a 0.5deg difference in toe between each one.

If you take as an example the rear of a 415MSX (so zero degree rear hubs, i.e. all the toe in is set on the suspension blocks), say you want to run 2deg of rear toe (which is about right for 27t), now you have a large number of options.
You can either have a wide rear track by using 1X on the front and 1D on the rear, or a narrow rear track by using XD on the front, and 1X on the rear.
The level of toe-in is still the same, but the car width is different.

Generally it's been found that narrower is better outdoors, it gives more grip, and quicker rotation, at the expense of some stability. Indoors (on carpet), it seems that a wider track generally works better, as the car seems more stable.

I've just had a look at a TA05 manual... looks like you need the following to work on your car.

2x TAM53685 Suspension block A-Bridge [these are the ones that go over the belts, so the front-rear, and rear-front block]
2x TAM51065 Suspension block 1A [goes on the front-front block, the one you broke, and the rear-rear]

Thoose parts take your car back to as it was. It doesn't look like there is much option on tuning the track width with a TA05... looks like the most you can do is tune the rear toe in. You'll probably want to get

1x TAM51066 Suspension block 1B
1x TAM51067 Suspension block 1C

That will mean you can also have 2.5 and 3.0 deg of rear toe in.

Hope it helps
Ed

I've never owned anything Tamiya so forgive me if this is a dumb question. Do all those blocks come with the MSX or is that like a little kit of blocks you buy?

the MSX comes with 4 blocks. off the top of my head, i forget which ones they are. sorry.

there is a world champion kit.. it comes with the XD, XC, XB, XA, rear alum. 0 deg hubs..and a locked center pulley. #49351

the rest of the blocks can be purchased individually.

Simon,

My suggestions are (in order):

Lower front ride height.
Add toe-out to front end.
Stiffer front springs (Tamiya blue or white)
Lighter oil in front shocks (30-35w)

Can anyone explain the difference in using at the rear wider suspension blocks with narrower wheel hex and narrower blocks with wider hex?

For example D/X with 4,5mm hex (standard MSX i think) it is 2.0 toe in.

And X/XD with 6mm hex, also 2.0 toe in.

From our friend Mr. Sunshine in Switzerland, an excellent overview of the suspension mounts:

With HB wishbones? Is that the short wishbones which are on the evo V or something? Anyone know how they would effect the car and what other parts are needed?

Cheers, Charles

I just finished building my Tamiya shocks for my new 415 MSX. Wow they are nice and easy to build, very smooth. I am impressed.

What hobby shops carry Tamiya 415 msx refinr 2 parts in Souther California? I will be there on business in the coming week and I would like to pick up some parts as Speedtech is out of the parts I need.

Thx
