Just placed an order for an M08 tonight. Can’t wait to get it! My first Tamiya M chassis was in 99. Which was the M01, had the M01/M02 few M03’s and 1 M04. Can’t wait to start building. I still have my BMW Z3 body from the old M04 I’m going to use for the M08.

quick question.. what is a MUST HAVE upgrade for the M08? I still have some old x pattern tires that are still sticky, and a set of Tamiya Racing springs Set from my old M03R. Anything I should buy for it right away?

If you’re on carpet the sway bar kit is an absolute must. The kit springs are probably not the best for higher grip situations either but ymmv. I also really like the new ball cups as they remove a lot of the slop across the board. If you’re building the kit might as well put them on the first time.

I recommend the 42168 spring set and some anti-roll bars
Gett the 54532 TA06 geardiff outdrives, That will provide some extra protection for the universals and outdrives cause you are able to use blades.
5mm shim set and some spare parts are always a good idea to have

Amusingly, I've sometimes found the stock plastic bits to have less slop than the aluminum bits, of any manufacturer.

Thanks for the picture!
I thought it would crack the other way, at right angle to the hinge pin.

So I will design the whole bottom part with a thicker outer diameter and with a hole to directly insert the hinge pin, without these shells.
Which caster angles should I design?

Sculpteo does not support any customer shops rigth now :-(
From shapeways I still didn't get any answers :-(
(Does anybody here has a shop at shapeways and know what to do to get the parts visible for all users? Please PM me to not get offtopic.)

Hi Slotracer,
nice to meet you in this forum, too!
I would propose to build the std. caster angle, which is 2 for M08. 0 degree is available by using M07 C-hubs, so a second geometry which makes sense is 4 caster angle.
Together with the Tamiya 4 lower suspension mount, you have some options for getting in some kickup and resulting caster angle.

Kind regards,
Matthias

On the arm that attaches to the servo, I used [email protected] 6 x 0,1 mm shim. I placed them inside the arm and then installed the bearing. On left arm I only needed [email protected] 6 x 0,1 mm shim. Yours may be different

On the bridge I also aded 2 @ 5 x 0,15 shims ( 3racing has halves). These were in addition to the [email protected] 3 x 0,1 mm shims per the manual. I also coated the shims with Finishline Ceramic Dry Wax Lub (used for cycling)

At present all play is going from steering linkages.. the only play I have is from the plastic uprights
I'm still not 100% what size shims you used based on your description?

Hi gents,
just ordered an M08 kit and was wondering about the new Tamiya ball cups.
Are they P/N54870? How many would I need for the M08?
cheers
Mike

So i got a whole lot more time on my M08 this weekend. It drives like my old, open diff, stadium truck. I'll pick up a tire and spin the inside tire, and perhaps, even spin out.

I have the stock springs, carbon shock towers, and swaybars on the car. It was picking up the inside tire, and diffing out in many corners, so I ended up disconnecting the swaybar. That seemed to help.

Try thicker diff oil too. If the grip is there, the thicker diff oil will actually make it easier to drive on corner entry. A little more rear toe in can help too.
