I've found out that the tamiya tire give me more speed in the straight away than the smaller hpi x patterns that I was using.

that is because it changes your roll-out. bigger tire = higher top speed.

I do have a couple question on tires though;

1 - Tamiya has codes for their tire compounds (A,B,S...) What are all the ratings and could someone rate them softest to hardest for me?

2 - What sites keep a good stock of tamiya tires and have a fair price?

Thanks for the help.

The long gearbox joint goes on the right side of th diff.
It goes like this

pressure plate A
thrust washer
diff spur gear
thrust washer
pressure plate B
"Gearbox joint" long

Now the full assembly

Ahh here is a pic.....

On the F201 A is softer than B

* The S-Grip tire is softest and good for asphalt surfaces that are fairly worn and slippery
* M-Grips are harder and best for carpet (don't ask me why, just take my word for it) Many carpet tracks also report that the stock tire and/or original super slick (both of which are smaller diameter than the S-grip or M-grip) have the best traction.
* Type A belted radials are pretty much the all-around work-everywhere tire. With different inserts, ranging from double stuffers (see the Tamiya website article by Dave Beale) to plain old 60D Tamiya foam strips, you can get decent traction and handling on virtually every surface.

I keep a variety of S-Grip and Type A tires with various inserts in my bag unless I'm heading for a carpet track. Those usually will get me where I want to be.

Thanks Nova!

Go on eBay and look for WalaWala store. I've seen him sell Pit Shimizu products.

Thanks for the lesson in rubber compounds

Any other ideas on where I can go to get Tamiya Tires? Tower Hobbies is out of stock on a lot of what they carry. Stormer Hobbies site says they have a very limited amount. Anybody have any more ideas?

Hey DOC can you e-mail me or PM me

Mike-
If HobbyWorks doesn't have them they should be able to order them in time for Laurel. Otherwise, go right to the source: Tamiya America in CA (1-800-TAMIYA-a). You'll pay list price plus shipping, but they usually have them in stock.

Troy- I'll hit you with an e-mail, as I don't do the pm thing. FYI my e-mail addy is [email protected]

Glad to be of service... I started typing it out and said the *(&%$&(*)%$ with it!!!!

I was wondering what is the wheelbase for the tamiya m-04m? I have the alfa romeo body right now but I need a basher body for it. I saw on the tamiya site that the m-04m has a wheelbase of 225mm, is that correct? If it is true, can the hpi civic mini body fit since it is also made for 225mm wheelbase chassis? Any advice would be appreciated. Thanks in advance.

ill check this eve... i have a number of the HPI bodies, both the short and longs. they sold both 225 and 208, i think? let ya know later....

the HPI civic body is 225mm. I had to get the longer chassis piece for my MO2 for it to fit right. So that would equate to the M01/2 Medium length. M04M for the miata is 225mm.
