Depends on your uses, I've added a couple that I especially like.

• Some sort of front airdam or spoiler to improve high-speed stability (most useful on un-lowered cars)
  
• Improved differential mount (RT mount or similar)
  

In the order I added them after buying my Z in 1971....

5 speed, Electronic Dizzy, Internally regulated alternator.

WHICH S30?

Electronic ignition, if it doesn't have it already.

Modern fuel injection? (I'm watching the MegaSquirt folks with interest.)

Later model alternator.

Heftier alternator wiring.

Headlight relays.

Maxifuses to replace fusible links.

Some sort of engine defeat, so some ne'er-do-well doesn't destroy your car.

Ray,

This is in no particular order and as Arne mentioned it depends on how you use the car.

Replace the bushings.

New headlights.

New Headlight harness, parking light harness or anything else Dave Irwin sells.

Different seats or reupholstered stock seats.

Rust treatment.

Ztherapy Carburetors.

Replace differential mount.

5 speed transmission.

New stereo.

Refurbished clock from Ron at Zclocks.com.

Ok Guys

The rear differential mount has never been replaced, so what improvement can I expect from this.

Ray -

You will get rock hard solid shifts with no give that the stock set up has - over the years that support will give a lot of flex and then you will get the dreaded "thunk" of shifting gears. This is the correction to get that "thunk" out of your shifts and nice smooth shifts regardless of rpms or speed. This is a must for any Z car owner......just ask any of us that have finalized this modification to our cars. We would never go back to the stock set up.

Power steering.

But then I'm a lazy old bugger.

Oh, and Toyota four pots and vented discs.

Just remembered another. Daves headlight relays.

I had this problem about 5yr. ago and traced it to a bad u joint on the rear axle shaft. The dreaded thunk went away.
