For the dif cups and front steering blocks, I used the supplied HR screws. For the chassis braces, I continued to use stock. If it's a gear box you're installing, I would use the HR as well.May seem a silly question as on face value they look the same!
But when fitting HR parts do you use their supplied screws/bolts or reuse the Arrma ones?
I don't know how much truth there is to this but supposedly Hot Racing only supplies 10.9 grade screws, again not sure if this is true or not, and the stock Arrma screws are all 12.9 grade.
Oh well i guess that answers that question lol.?? Should of looked at the screws!
HR marked 10.9
Arrma 12.9
