Great! Glad I could be of help. You won't regret getting the TB03, its a awesome car. I'm glad to hear there is parts support for Yokomo where you live, I like there cars as well. One of the best looking TC ever in my opinion was the SSG version of the SD. Beautiful car, very fast too. My friend JimmyMac raced one back in the day....I drooled everytime I saw it

TB03 is a very easy car to build. If you have any questions when you get your car don't hesitate to ask. We are all here to help Hop ups are easy to install as well.....and addicting!

As far as the posts about adding grease to the crown and pinion gears, I personally do not add it to mine. It just adds drag in the drivetrain, and isn't really needed in my opinion. Now if you are drifting your car, then I could see where a little extra insurance couldn't hurt. Drifting, your drivetrain will be at a pretty high rpm all the time and a lot of the drift guys are running spools*direct coupler* in rear, one ways in the front, all kinds of setups that add a lot of load to the gears even if the tires are spinning easily. Here, a reduction in friction(heat) in the gears could prolong life with the parts.

But I do add something unique to my gears that I doubt many people have tried...*braces for redneck jokes* Remington Dry Lube. Its a dry film lubricant I use on guns LOL! Just a quick spray adds a very fine film on the gears. Does it make a huge difference? Idk maybe not. But when I put a shaft car together, ever little gain I may be able to make is worth it to me. Dang I got to get off the internet I'm telling too many of my secrets lol

Hi kerk!

AW grease on gears would be BAD! you would have mechanical drag brake Looks like it has a graphite additive to me. It's awesome stuff though, like Fat said i use it on my axles as well. Its some sticky stuff thats for sure. I hate getting that stuff on my fingers

Thanks - I've been adjusting my front and rear droop a bit, but won't have the chance to really try it out again until this weekend. I'll see how the car handles then

I am not a Tamiya grease expert. But I will still give my opinion

They are both probably lithium based greases, as are most greases out there, that they either add a ceramic additive or a molybdenum additive. Relating that with my experience with real life cars, moly grease is used for very high load bearing purposes, high temp,high speed, low speed,.. basically extreme enviroment. Ceramic greases are usually a mid grade grease used for lighter load bearing, high speed applications. Both are good to use on lots of things and offer similar performance in a lot of areas, but for heavy duty I would use the molybdenum.
My suspension setup? Eek - I'm really not all that precise i.e. I haven't really been all that precise measuring stuff. I'm running about 2degree negative camber front and negative 1.5rear, "some" front toe-out ( haven't got the instruments to really measure this) and the default 2.5degree toe-in rear , about 4mm ride height in front and 4.5mm at the back. PROBABLY about 2-3mm droop in front and 3-4 rear. 400 oil (tamiya yellow) in the dampers front and rear, with the white springs (I think they're the same as the yellow springs?) that come with the shocks.

I've also just added 1mm spacer to the front IFS shock mount, 0.5mm extra spacer to the front/front suspension mount (to increase the caster angle?), and moved the rear shocks to a more vertical position (top, second hole from the outside). I've yet to try out these changes though...

Ha ha...I'm pretty sure I'm just making a mess of things, but...mucking around is fun

I use ceramic for anything plastic, and moly for metal to metal.
I'm glad I asked that question about the grease - looks like I'm not the only one who likes to know Everyone has been so helpful in this forum. I'm really feeling the love here... heez!

Thanks all!

Smile TB03

TIMMIE,

AS YOU CAN SEE IN THE LINKS I BADLY NEEDED YOUR HELP . Right now the kit is just for the show and not for the race yet. If you would need help on the write up on the low down step by step build up for the TB03 then let me know. I will be waiting for your emails can't wait to rebuild the kit.

Swift,

If you don't already have them, I'd go pick up some cheap digital calipers and measure all your turn buckles. Make sure to get them to the factory lengths that are in the manual. I'd wager that'll fix your toe-in.

What kerk said would work, I would try the anti squat, this prevents weight transfer rearward on power, giving you more steering on the front end. But I personally would try some other things first because in my opinion its a pain to make this change on the TB03. The inner blocks are buried and you have to take a lot of the car apart to get to them. The only time I have felt I needed a adjustment like that with this car was at the last race I was at running high grip indoor asphalt. There I ran a little anti dive since I was running a one way front diff.

Do you have wear on the edges of the bottom of your chassis? What kind of track surface and grip level are you racing on? 4-4.5mm ride height is very low. If you are pushing on power it might be from you dragging your chassis around. The white springs you have don't have a small dab of paint near the flat of the spring? Yellow's are pretty soft so If you are running that low of ride height I imagine your bottoming out. For outdoors I always start at 5.5 front, 6mm rear. As the day goes on I will go ahead and lower it to 5mm front, 5.5 rear and see what I like better that day. Running the height a little higher helps the chassis roll more helping the car turn better. It also keeps you from scrubbing the chassis or body in the turns. If anything on your car ever hits the track in a turn you need to fix it. How do you measure droop? Yes you increased caster when you added the shims to the front block. Along with what you have done, another thing you can try to loosen up the rear some is run a lower roll center in the rear. How many shims do you have on the rear uprights?

Haha well everything else looks pretty good from the pics, you just got to fix your toe in. I would do what blue said, that should straighten it out for you, I'm still confused how you did that, I guess you just looked at the wrong measurement when you built it.

I'm waiting on my new chassis to show up in the mail today. As soon as I get it I will take my car apart tonight and start working on the write up for you and anyone else that wishes to look at it. I'll try to be as detailed as I can

+1 on the dry lube, though I have never tried it on driveline parts, I do use it it on suspension pins and balls/cups. The brand I use leaves a whitish film, so I just spray out a little into the cap and apply it with a q-tip or dip the parts in it and let them dry. Be careful spraying into the cap though as it can spray right back into your eyes...I do it in my kitchen sink and hold it all away from my face. Be sure to test it on a sprue scrap first, as some brands might use a base that could eat plastic bits. Any auto parts or "Big Box" store (I'm on vacation from the orange box right now so I refuse to utter it's name at the moment!) should carry it.

In sealed gearboxes I similarly use a spray silicone lube, but it can attract dust and dirt so I don't use it where it is susceptible to dirt like the suspension pins etc.

As it was already said here, tamiya hop-ups are addictive

I'm between buying a high performance car or building one with my hands. No question about which opportunity would be more expensive. The TB-03 got this beautifully arranged inside front shocks. The TB EVO has not. I think this is the point why to start up building a CF-deck TB-03 (IFS). I still want the Takata NSX body which won't fit a TB EVO.

My poor wallet.... ....made of onion-leather. Everytime you're looking into it, you'll be crying.

It's really good to see this thread jumping!

I'm really enjoying this car waaayy too much.

As Timmie said Hop Ups can be addicting but I'm staying as stock as possible.

In the series I'm running (RCGT Showdown) my two top competitors are (supposedly) running stock out of the box JL10 and Cyclone cars. Though the Cyclone is a bit out of the "Budget" range the JL-10 is priced right along the TB03. (Although you only get a chassis kit, no wheels tires, motor or body) it's $130 price tag is attractive to new comers.

Soooo, I will be testing the stock shocks this weekend and building them to match the performance of my TRF's (or there about)

I also may take it a step further and ditch the sway bars. We'll see how it goes.
