i have noticed on a hard 1st to 2nd shift and tires bite that there is a thump/clunk/bump i hear and feel that seems to be mid to rear on the car....anyone else ever had this, where should i look for signs of wear....trans mount?....rear sub bushings?

Probably the bushings for the diff.

I'm surprised no company has made polys for these and motor and transmission. It would definitely help the car feel more solid. Speaking from experience with my Z I had.

Wheel hop is not uncommon on cars that are built with an IRS suspension. I've read here on the forum that it is common with most Toyotas.

The front and rear bushing kits for the IS F differential is supposed to cure the wheel hop. Remember this differential is big and heavy, which just adds to the problem. Figs is an excellent source for this cure.

The new 5 liter Mustangs have the same issue and Ford came out with a complete kit to fix it. The fix resulted in much better quarter mile times with better car control allowing the car to accelerate in a straight line.

Good attempt to avoid crowds.
