jayyraad Member 19 Member For: 12y 2m 16d Posted 18/09/12 10:49 AM Share Posted 18/09/12 10:49 AM Iv looked at one too.. Powerbond is reputable. And yes prob worth it. My.mate has a powerbond underdrive kit on his mk2 gt... Revs pick up fair bit quicker. The balancer is at least half the weight of the factory balancer. If you are unsure. Look at atomics balancer they are the best and you can never go wrong with any of there products. As for the removal. Yes quite easy however you do need a special tool to remove the balancer. Normal balancer pullers are too big and or dont lock in behind it properly and.you will fk it up. Link to comment Share on other sites More sharing options...

Could it be that simple? Link to comment Share on other sites More sharing options...
