I bought these for my TA05 M-Four and while they look like they fit the chassis mounts (I didn't even open the packets) they will unfortunately push the front and rear track out by a mile. CVDs and upper tie-rods won't reach. Fine if you want to get the wide buggy look but otherwise no use to me!
Please note that these DO NOT fit the IFS TA05's. These are for the first generation TA05 and non-IFS TA05's only. I do like the color and how it complements the Tamiya blue but the problem with alluminum is added weight. When this weight is forced against other plastic components in a crash the chances of breaking more than one part is very high. In my opinon and use, i would not use these if you run or race your car frequently. If you use your TA05 as a shefl queen, these are a nice addition. Good price too!
