Mix and Match springs??
I currently have B+G springs on my car and the rear is a little too low. Would it be adviseable to mix and match spring types? I am thinking of putting Tein S-techs on the rear and leaving B+G on the fronts since I am happy with the drop there.
Advice??

Their is no valid reason why you can't do that other then overcoming your own personal superstition's. Fact is, you take 5 different aftermarket springs for the G and Z and look at their spring rates, they are VERY mix and match! (Take a look below at how all the spring rates are all over the map and you'll see what I mean).
Eibach's as noted (first number is the softer initial rate, followed by the higher final rate)
350Z 296/384 front 316/421 rear
G35c 229/337 front 274/463 rear
G35s 259/334 front 359/413 rear
RSR 350Z springs (just a wee bit progressive F&R, maybe one coil is progressive)
345/417 F+10% R+22%
Transfers +12% roll stiffness to rear
RSR G35 coupe springs (progressive front and rear)
315/315 F+0 R-8%
Transfers +8% roll stiffness to front
Hotchkis 350Z springs (linear springs)
340/330 F+8% R-3%
Transfers +12% roll stiffness to front
Tein S-tech 350z (fronts are progressive, rears are linear)
386/402 F+23% R+16%
Transfers +7% roll stiffness to front
Tein H-tech 350z (fronts are progressive, rears are linear)
358/375 F+14% R+11%
Transfers +3% roll stiffness to front
Tein H-tech G35 coupe & sedan(fronts are progressive, rears are linear)
324/260 F+ 5% R-22%

Espelir coupe springs (the U.S. importer recently changed specs, I do not believe the newly listed specs are correct, since the new one's are extreamly high. And when I called the company to ask if the springs are linear or progressive, they told me Linear, turn's out they were absolutley wrong, they are in fact progressive. I show the old specs for those reasons, take it with a grain of salt, same thing for the 350Z fitment)
