Ok, I did make it to the track this Friday. (ran a 14.74 @ 96). Video is in the racing section.
I'm impressed with the Phantom Grip and also the Exedy 3-puck (stage 2) race clutch.
Both parts took 6-7k rpm speed shifts like nothing... just a nice agressive *bang* as the clutch grabs.
So my ~1k mile and drag strip review is a big thumbs up for my drivetrain modifications.
This includes the Phantom Grip, Exedy clutch, poly dog bone inserts, and tranny poly mount.
I probably won't have many more details to add unless something goes wrong.
I will say my general drivetrain noise has increased significantly, but nothing alarming.
