JQB0908 – THE Rear Arms THE JQRacing Rear Arms are solid. They are interchangeable left to right, and we have included 2pcs. JQ: If you don’t believe us when we claim the arms are solid, check out this test video we made: YOUTUBE. Normally it is best to change both arms, even if you think that only one needs replacing for some reason. This will make the car handling more consistent. Unfortunately, due to us having changed the material of the arms back in 2011, we suggest that you use a 4.2mm drillbit, or arm reamer, to make the suspension more free, as the hingepin hole is a bit small.
