Haha perfect, got a whole bunch of blue AE 1mm and 2mm washers ready to go. 
Don't want to risk messing up my oil filled diff and coupler! Ordered a pack of various socket head hex screws too, so now I got the hex head screws covered, those should be here tonight at some point.
Now I got my 3mm and 5mm shims, hard chassis, and a fresh pack of USGT tires (TQ RC was out of the belted ones
). Time to switch over the chassis, get rid of the remaining slop, and go back through and make sure I loctite everything that needs to be this time just to be safe.
Just discovered the Cal Raceway down in Orange last week too. Might have to go pick up a 911 GT3 R body now so I can get some practice in their Porsche class before the TCS at Revelation next month heh.

This will be all asphalt. I honestly don't think there are any carpet tracks anywhere near here in So Cal, indoor or outdoor. Even Tony's Hobbies, the track is inside the back of the warehouse, its all dirt (but now they wont let you run anything but slicks on it, all my Hole Shots down the drain heh). Its nice for me, I'm old school and like my off-road buggies in the dirt and my TT-02 on a real track.

It's possible. If you really want to do this, go to Tamiya's website to look up all the option parts the SRX offers, and source those parts individually. However, it's much easier to just get the SRX kit and be (mostly) done with hopping up the car.

And then you still have a base TT-02 you can switch around to a rally car and go have fun on dirt, and keep the SRX for the track!

unfortunately those are too long, you will never get the right wheel base and Tamiya USA is sold out of the correct ones. I ventured down that path a few yrs ago and the project still sits on my work bench. the only real way to get those is to purchase the SRX kit.

Those in the picture are the correct ones for the Type S series. Not sure why you are saying they are too long. They fit the S, SR and SRX just fine. You are correct that is individual parts they are sold out, but the compete S parts bag is available.

They will function mechanically, but if you're trying to convert a TT-02 to an SRX setup with the intention of using Tamiya bodies, the result isn’t ideal. The wheelbase ends up being too long when using the inserts mentioned earlier—especially when paired with a Tamiya pre-cut body. I went down this path myself, and while it technically fits, it ends up looking off. Trust me—you’ll want to locate the correct inserts shown below for a proper fit, or simply go with an SRX kit..
Whats the part # for the S Parts Bag and is that from the SRX?

Tamiya makes bodies in 257 and 251 wheelbase. Majority of the 1/10 bodies are 257 mm bodies that work with the SRX. There are only a handful of 251s,
mainly the Porsche 911s, new Audi Quattro IMSA. The Mercedes AMG GT3 originally was 257, new version that just dropped is 251 mm.
