The plastic parts in this set are the same as the original and the price is good.
However, if you have wrecked the front hub carriers, like me, you have probably lost the small metal things that go inside them (Tamiya part 51100). So remember to get these too:

The RC Mart page doesn't say so, but the parts number matches the DF-03Ra guide.
