I still have the original struts and shocks on my 1990. its been tucked away for 22 years, and I am now in the process of breaking it back out. needless to say, I'm in the market for new ones and ran across a few articles during my research.

Great article on a 3rg gen pulling .996 g

This is eluding that the correct part number for rear springs is : 10305134 - I'm guessing since (NNL,NNM) is listed first, and then
10305134 is listed first, they match up.

SPRING,RR(CODE NNL,NNM)(REPLACE IN PAIRS ONLY). SPRING,RR(CODE HS,HR,HT)(REPLACE IN PAIRS ONLY). SPRING,RR(CODE TF,TH,TJ,TK)(REPLACE IN PAIRS ONLY). SPRING,RR(CODE TP)(REPLACE IN PAIRS ONLY). SPRING,RR(CODE TD,TM)(REPLACE IN PAIRS ONLY). SPRING,RR(CODE NUX)(REPLACE IN PAIRS ONLY). SPRING,RR(CODE TB,TC,TD,TM)(REPLACE IN PAIRS ONLY).
Stock Code 10305134 ; 10018092; 10021570; 22077421; 22132889

Alignment 101







One key thing he doesn't explain for our cars what angle to draw line from top of strut - it should be at a 90 degree (right) angle to the strut.

Confirmed my factory springs/swaybars today:

Front BZW 14029397 (passenger side), 36mm sway bar
Rear NNL 10018091 (driver side), 24mm sway bar (if it was 24, it was 25, really hard to measure!)

Springs almost in line with Crazy Hawaiian's figures

Stock ride height measurements - ground to wheel well

FL - 27-5/8
RL - 27-5/8
FR - 28-1/4
RR - 28-1/4

Body weight wearing springs down on driver side?

Some other qualifications to this measurement:

Stock 16x8 rims,
T-Tops removed
Original shocks/struts are blown
Tires are 245 front / 255 back (specs over here: https://www.thirdgen.org/forums/whee...ml#post5965465)

Thanks for doing all the work... I'll need this once I get in to suspension tuning.
