TheRcRacer Tamiya TT02-S Rear Adjustable toe plate
https://www.thercracer.com/2020/07/thercracer-tamiya-tt02-s-rear.html
With a lack of racing in lockdown I have been designing a few parts to show you all. First up is something that I have been tweaking for some time for my Tamiya TT02-S. The Rear adjustable toe plate provides a lightweight solution to adjust the rear toe on the TT02-S.
Fitting instructions.
You need the following- 2x6mm CS screws (can be 8mm or 10mm if needed), to attach the Tamiya suspension block.
- 3x8mm CS screws to attach the plate to the chassis.
- 2mm spacer with a 3mm hole (Tamiya 53539 is ideal). (Not needed but good if you want to make the surface contact stronger)
- 1 x Tamiya 54880 Aluminum Adjustable Suspension Mount (XB). **Note** You can use other mounts but the XB block provides the best range for stock racing.
You attach it to the three holes underneath the chassis. The middle screw hole is 2mm lower than the outer holes so I used a 2mm spacer. This spacer will ensure that you get a better surface area against the plate, making it more secure.
So just screw in the 3x8mm screws. Fit the centre screw first and then move onto the outer screws and make sure that it is straight.
All finished :)
Changing the rear toe
As the block is adjustable you can select a range of toe-in that you need. I have provided a chart below. You can use the adjustable blocks, or the older suspension blocks if you have them at hand.Changing the Suspension pin height
With the Tamiya blocks you can also change the height as well as the width. This changes the angle of the suspension pin providing you with rear pro-squat / anti squat.Anti-squat is where you lower the rear suspension point, it basically helps you have more steering response, sacrificing a bit of rear grip.
Pro-squat is when you raise the rear suspension point, this provides more traction and reduces the initial steering response.
For lots more detail, on all of these settings and more, check the suspension guide I made here (Click link)
Weight Saving
The new part also saves weight. The 3.0deg plate standard part is made from steel so is strong but very heavy. With the droop arms it is 13.34g If you add the additional rear bumper mount that is needed to secure the pins it weighs 28g overall.The SR adjustable block with droop arms weighs in at 16.92g
The Droop plate with the Tamiya adjustable mount weighs in at only 7.35g saving 6g of weight over the standard S rear mount (20g with the plastic bumper mount), and 9.5g over the new SR rear adjustable mount.
Overall
Over the standard part on the TT02-S you get a wider range of adjustments. With the XB-Block I can go between 0 and 2.5 degrees of rear toe-in with one block.It also provides the ability to use the droop screws without needing to purchase additional parts. Droop is an essential part of tuning, and you can now easily adjust it by changing the droop screws.
Oh and the end result is you have a nice Tamiya piece of blue bling. What more would any Tamiya fan need :)

Disclaimer and thanks
These have been made as a contribution to the Tamiya racing community. There is no profit for myself and the parts can be ordered directly via Fibrelyte. These are just a tuning aid, I found them to work well, as has others who have tested parts. Every track / driving style is different so do not expect a golden bullet.
Thanks to Steve at Fibre-Lyte
This is a simple part but was inspired by some of the amazing work Kevin Kreft has done on his TT02 Total conversion, which takes a TT02 and makes it look like an awesomatix.
I have invested my own time and money in these parts for the Tamiya community, at no profit for myself. These designs are always helped via feedback from other racers. So please let's share feedback and set-ups and I can try to refine or design other parts in the future :)
