Advice to all who buy this product. Take care when you mount it in the car, because you can easily mount them in the wrong way. One of them is from the left side, and the other from the right side. If you mount them in the wrong way, you'll have adjust the wheels position. I suggest to take each piece and compare with the stock ones to check the angle of the mounting in the right position.
Screws not included. That's just great. Well anyway, will this stop the screws from falling out? My screws fall out every ride and now I'm all out of any screws that'll fit. This is the only annoyance I have otherwise it's a great car.
Yes if you use threadlock glue on them. I also bought some ball bearings for wheels to put instead of those ****py all metal "bearings" they use by default.
8x4x3mm fit. I bought and used "HK450V2 Bearing (8x4x3mm)"
