munchee,
if ur planning to use a short stroke with ur tein, it is advised to install a rubber buffer in between the springs to avoid much bounce which will scrape ur fenders.. other wise it will be too low.. or u can opt to knock ur inner fenders.. best choice is to use what i said b4 (stock shock+lower/sport spring) or (short stroke shocks+stock springs)
boon,
n yes.. different models n brands of shock or springs do make a difference, in height or in performance.. mixing springs+shocks is hassle combo.. some like to combo it this way n some other..
for springs.. i advise to use Eibach,Sparco,Tein n Tanabe... other brands tends to lower the rear too much,once got pax or load.. then finish.. its scraping time..
