And if I leave the Rear parts as it is, the OEM disc is 290 x 18mm.
I am wondering is there a need to upgrade the rear disc?

Not just for the performance, but also for the looks as well.

Or maybe I just chose the Essex AP Racing Big Brake Kit (SPRINT) - 299x32 mm version. It is 600 USD cheaper

I don't do heavy track. I DD my 86, but spirited driving my car in any chance I get.

Any feedback will be appreciated.

I think the sprint kit is magic with more than enough headroom in braking capacity....and the weight saving is a bonus.

You certainly dont "need" to change the rears... but then most of what we do isnt strictly "needed"...
I changed the rears to the STI 2 pots and put slotted DBA disks on, looks better, easier to change pads, might perhaps be functionally better in some ways in some instances...but makes me feel better.
I haven't been able to detect any negative brake balance issues since doing it 5 years ago...and I suspect given the degree that I've changed the dynamics of the car, whatever the standard brake bias was, I doubt that it would have any meaningful relationship to the way the car reacts now.
