So if I'm on a hill and ease the clutch out I get a wicked chatter and clunk.
Almost sounds like my exhaust is banging on the floor board but looking at it Underneith I don't see any clearance issues.

the brace the runs under the mid pipe is close, but not touching unless it does when torque is applied from the engine ?

The Car has a exedy twin which is normally smooth for the most part, it doesn't feel like clutch chatter cause I've had some rough clutches before, I have a Perrin downpipe.

I also did a launch from a dead stop and got some wicked wheel hop. I got out of it right away but it didn't feel good.

What at should I look at first?
Im guessing engine mounts but they look ok visually? Although the rubber could be worn.

I also get a bad clunk when I get on and off on the throttle in 5th gear.

any input ?

 

Time to put this on a lift or a set of ramps & check the rear diff bushings. Possible rear diff clunk going on

Check the driveline mounts & the u-joints as well
