I installed the Race Tech Gold Valves and it made a night & day difference in the front. It might [?????] be possible to use the stock valving though. #1. Drill out the very small holes on the top plate as large as possible. These tiny holes can't flow near enough oil when encountering square edged hits. #2. Remove a couple of the shims[there's 8 of them] in the stack below that top plate. I added these discarded shims to the rebound valve stack as the stock rebound is too quick. Let us know if this works .
