Anything but a TT for racing.
You can get an Ackerman steering set from Tamiya for the TA05VDF, but it's not as affective as it could be. As said, it's primarily a drift chassis.
Some online sellers are still clearing out TA05 IFS kits at good prices. Not the newest design, but a proven package and will accept current spec Tamiya TRF steering and suspension parts if you want to modernise it. Plenty of carbon parts available for it too.
