Bought these ones because if you buy alloy ones, or carbon reinforced plastic ones, if you hit something, there is something else that will crack/get damaged.
And these suspension arms are soo cheap, so if you crash you don't have to buy a shitload on (new) alloy parts !
I wrote on a forum that the Tamiya TRF501X racedriver fit some of these suspension arms in the last couple of races, because these suspension arms have just that little more flex, so it kept better on the ground, so it has that little more grip on the track, and it showed better results, and he was World Champion !
Does that say enough ?!
Recomended to buy a set of spares of these, especially the rc drivers that don't live in HongKong or somewhere else, because IF you crash, you have to wait till you get your parts from RcMart, and if you live in The Netherlands or somewhere not beside HongKong, you have to wait longer, and most rc shops in the neighbourhood sell DB-01 bits, they have to order it too, so if you buy them here, you just can replace it and can race with your friends again !
So DB-01/TRF501X users, buy these as a spare part !
Great product for a great price !
