I know this has been hashed out a few times, but I didn't get a clunk for 3 days after install. I installed the UPR solid upper and mount (because I scored the both for $120) and I put the car through it's paces pretty hard with no noise. Then suddenly today will just driving normal I noticed a clunk. It happens while shifting, mainly fron 2-3 and 3-4 and when pushing the clutch in. I know many people get a clunk but why would it suddenly appear 3 days later and not immediately? And I was listening for anything after the install and there was no noise. If this is related to the solid UCA then replacing it with an adjustable one isn't that big a deal, like I said I got the arm and mount for less than just a mount normal price
