I now have Tien S's on my LX . I did have the MP3 spings . It took me 2 hrs to do the swap .
In the short time i have had the new springs in ,i will say it does make a big difference in the car . Not only is the drop even all around ,3.5" from the edge of the fender to the edge of the rim (17's) .the stance looks great . The car has much less body roll and is more responsive on the turn in . For you Mazda speed owners its an upgrade worth doing .
I still need to get an alignment ,once that is done the should be even better handling .
If you are doing the install yourself you dont have to compress the rears to install them on the strut but the front springs will need to be compressed .
Heres a bit of FYI
Factory springs front 121 lbs/in ,rear 97.5 lbs/in
Mazdaspeed front 145 rear 117.5
Tien S-Tech front 179 rear 145
The Tien's have a 67% increase in spring rate over stock.
All three springs are Linear in there response . (greenpro)
