I did the Tamiya Alloy bulkheads and all the hop ups to a TA05R I had last year. Its not really worth it, It will be nice, but you can buy a used 415 or 416 and be better off. I ended up with a 500 sum dollar ta05, then I bought a used trf416 for less than half that. Just rock the ta05 the way it is, its a good car. Save your money towards a better car. Just my opinion.
