Here's a weak part of the front end after some hard bashing. This is a result of the aluminum a-arms putting more stress on other parts. The rear plastic toe block is also a part that has seen more breakage with these aluminum a-arms. You can see the rear toe block in the last pic above. I am probably going to go back to plastic, but I will give it some more time. I have ordered the new front piece (7075 aftermarket) and will be ordering some aluminum rear toe blocks (there's two).
Here's a cool TT MT4-G3 poster, The Big Squid RC Bash Vehicle of the Year
Replaced broken rear stock a-arms with these GPM Aluminum A-Arms. Good looking, but not worth it. Puts too much stress on other parts. Makes this awesome durable truck seem like its made of glass. I've had nothing but broken parts after installing these. Broke the truck today within 2min. They are going to become something else in their life as I threw them in the recycling. Replace broken a-arms with stock until RPM makes some.
looked pretty sweet except for the broken part
