Hey guys I decided to go for springs as I'm on a tight budget, probably change them out within a year or so. Once again, it's a crossroads:
94+ Springs with 170,000km on them, $240
King Springs with 10,000km to 20,000km, $170
The kings are likely lows as they only manufacture lows for the SW20, 30mm drop.
Does anyone know the drop from pre 92 to post 93?
Also numbers for camber bolts for front and rear to adjust between 0 and -2 degrees of camber

Forget manufacturers advertised drop, cos your old springs are 20 years sagged.
On my car I got about 17mm drop with 92+ springs compared to my stock 90 model ones.
At one stage I also fitted Pro-Kits and they had almost the same drop as the 92+ springs.
 
BTW, stock shocks wouldn't last long with springs with a 30mm drop. You'd need heavy duty shock inserts like Koni, Bilstein, etc. 
 
Camber bolts:
Only go for the Toyota ones. Available at several places, but I got mine from Twos'rus.
They come in 3 sizes apart from stock, and you can identify them by the number of small raised dots on the bolt heads.
