This is a must have for your DF-02. Being genuine Tamiya the quality is excellent and everything just fits, like it should do. This set includes everything so you can adjust the camber greatly affecting grip and tire life. You also get a new steering turnbuckle set so you can adjust toe.
The shafts themselves are just coated in blue and the blue on mine is starting to wear off, but it's not a big deal. they still look cool and add the bling factor that most people crave as well as being useful. If your car is prebuilt you will have those horrible plastic "turnbuckles" that aren't adjustable. Get this set and you'll get rid of the RTR feeling that the plastic bits give.
All mounting hardware is included, although the wrench supplied is too thin so it's fiddly trying to adjust them. It works, but it's just fiddly. If you have more than one wrench, tape them together to double the thickness, it makes it so much easier to adjust.
Buy these over the other aftermarket parts. The quality is much better and considering what you get in this lot, the price is the same as the other brands.
