I have the front and rear brace, steering brace and engine mount on my 8T 2.0.
It maybe just me, but it seems to make the truggy handle better, than the losi alloy bits. The engine mount has an extended part which the fuel tank screws onto and it's finished in black anodized with silver trim.
It does seem lighter than the losi alloy bits, but I've yet to weigh and compare them.
On a final note, I've yet to break anything made by Kingheadz, where as I've sheared 2 losi braces due to hard landings.
