By How to Adjust Spring Preload on the BC Racing BR Series Coilovers
Let’s take a quick look at how to make your spring preload adjustment on your BC Racing BR Series Coilovers. On the MacPherson strut version, you’re going to loosen the lock collar with a spanner wrench and then loosen the lower spring bucket until it’s just about loose and you can turn it with your hand. Then, thread it just up against it without tightening it any further, then thread the lock ring right up against the base of it, also without fully tightening it and locking it. Holding that locking in place, use a spanner wrench to tighten the lower spring bucket until there’s just enough room to slide your BC Racing spanner wrench directly between which is exactly 4mm.
Make your adjustments on your spring preload evenly on all four corners, 4mm at a time. On the rear spring, on a non-MacPherson strut. You’re going to do exactly the same thing, but it must be mounted on the vehicle to make these adjustments and you’re dealing with a much larger lock ring.
