Its so clean! Looks great man! Love those wheels and tires, do you have part numbers for those by any chance?
I finally got all my weirdness (torque steer like issues) sorted out. Took a lot of stripping and rebuilding, checking everything. What really turned the corner (odd as it is) was removing all of the shims I used to take slop out.
Nothing was binding in anyway I could see or feel, but clearly something was binding "just enough". I loosened the car up (I had shimmed the universals, out drives, etc - anywhere with a lot of slop), and as soon I re-slopped up the whole chassis, suddenly (and go figure) it was super planted and a joy to drive.

It is a normal method here in Germany to add Shoegoo where the lexan might break to make the body tougher. Are you sure it were Tamiya rattlecan lexan colours like PS-1, and so on were this happened? Or was the colour not dried inside out?
I am doing this for many years now with TC and Tamiya F1 bodies and never had an experience like you mentioned. Strange, strange...

They seem pretty good to me, the quality is on par w/ other wheels i've bought from name brand manufacturers ...I can't tell a difference. They certainly seem like they'll hold up just fine.
The tires I have on there are a pack of Team Assosciated's

They are only $10 ...and are fine for parking lot bashing. I wouldn't use them and expect great grip ...not for racing. For parking lot they are perfect. Even on a high grip track they'll do fine (i've used these on some of my non-racers at the local track ...as long as there is sauce on the track you'll get good grip).

I tried it once and never again. ...I am guessing that the shoe goo was applied too soon after the paint job??? -I believe it was applied w/in the same day I painted the body. That could have been the issue?
In any case there was something I obviously did wrong.

Speaking of, I spent a little time tweaking my car on the setup station. It handles great. I gave it about 2-3degree of camber in rear and 1-2 in front (dont' have the exact numbers in front of me). Also the stock toe in in rear and about 2degree of toe out in front. ...I did some initial runs w/ the car (no body yet), and it is really planted. Steers straight and handles nice. I am actually impressed w/ this kit, for $120 or whatever I spent, this kit performs quite well. I may have to get one for my son when he starts racing as a first car for our novice class.

started work on the body this morning before work. I hope to have it complete early next week!

In my experience Tamiya kits (at least the kits I've built) like a little bit of slop. Its counter-intuitive ...but they seem to run just fine w/ 1-2mm of slop here and there. On my TT02 build the front wheels could be pushed in towards the chassis about 2mm ...There is a bit of slop in the front cv joints (which is what I used). I just left the slop ...testing my car it handles really well.

I got the wheels on eBay, -i was nervous since they are an off-brand, BUT since I am not racing this car I was willing to take a chance and there were less than $5 shipped.

I have to ask because I'm becoming a bit perfection obsessed with my TT02: I see many people talk about putting a TT02 on a setup station, ensuring X degrees of front toe out, etc. Here's my knowledge gap - even with the upgraded steering and turnbuckles, upgraded rear uprights, etc... there is still so much slop, easily 1-2mm front and rear, that how can anyone actually setup this chassis with a real "XYZ"degrees of ANY adjustment?
not sure if that helps/answers your question totally, but w/ a setup station you can really see what is going on w/ any car. I love using mine and makes adjusting the car super quick/easy ...takes all the guess work out.

hey, so I did a test the other day w/ shoe goo. It seemed to work just fine for me no weirdness on the paint. sorry, that I said shoe goo was bad w/ polycarbonate paint, i did have a bad experience a year or so ago and stayed away. Yet I am wondering if the paint was not fully dry when I first tried it? In any case it seems to work fine for me now. I did let the paint dry for an entire day and it was about 85* out.

Nice 
Yeah, maybe the colour needs 24h to fully dry out...
Good that it worked!

Don't forget chassis balance guys. That is one of the most over looked things to a setup of any type of car. You will want a 50/50 left to right with no more than a 60/40 front to back if not closer to 50/50. But 60/40 tends to work best in my opinion for acceleration reasons.

When I drove my TT02 after the build it seemed to drift a tad to one side when pointed straight. Putting it on the setup-station I could see that the toe-out angle on the front wheels was not the same, the left side was out about 2 degree whereas the right side was about 3.5 degree. I get that there is a tiny bit of slop, but still when I set my toe in to be the same on each side the car no longer veered to one side when pointed straight (when tested). I have a tiny bit of slop, it is very minimal ...but like said, many Tamiya kits seem to have this and trying to remove that play doesn't seem to be a good thing.

This is something that should be setup per outing, not set and forget like a setup station would subconsciously have you believe.
If you not running lathe trued foam tires, there will almost always be an indifference from tire to tire when it comes to contact patch. For example, if one tire has a slight offset on one of the sidewalls of foams, then it doesn't matter if your camber is set exactly the same from side to side, your actual contact patch will be different.
The tire it's self will take that balance right away and can only be tuned by feel and eye.
Then there is acceleration creep to be considered to. Seeing if a car is trimmed to drive strait down a line is only half of the attention it needs attended to.
Once you get your tracking right, then you need to adjust your spring pre-loads to achieve a hard acceleration alignment.
For example, if you gun the car from a stand still and it jumps one way or another, even if ever so subtle, (lets say right this time) then you need to tighten up the rear right spring with a bit more preload to get the pressures equalized from tire to tire.
Once you do this and your vehicle tracks straight, it is at this point your done with the trimming process.
Things like this mean nothing on paper vs actuality and be damned a setup table.

Did I mention how impressed I am w this car for the price.
Handles really well!
Now just need to get the body done...waiting for some pant to arrive.
