Tho when you build the kit per manual for eu spec there
14mm screws on the front and 10mm on the rear so im guessing the ball ends they would be the same length.
Sorry but from my experience this is wrong. I ordered 2 pair of each and have a set of 8 and 10 spares as I use both pair of 6mm on the steering links end of the knuckle and on the servo saver and I use the 8mm front and 10mm rear. I use the open ball joint ends for the wheel ends of the camber links and the closed ball joints everywhere else. With a little shaving of the rear open ball joint ends you can fit 5mm of shim under the rear wheel to really lock in the back end especially if you are using a gear diff.
You can use 6mm front if you run no shim and you can use 8mm rear if you run less than 3mm of shim there. Any less thread and you will find out the hard way that the knuckle and the toe block can break easily. i will post a pic later as i was a victim of this on the weekend as i left the 8mm ball end in and used a 1.5mm shim and my car broke when hit by a racing incident on the first corner of the 2nd A main
If you want to take it a step further use the Losi foam things to keep all the dust and dirt out.
