aftermarket alarm for e46

hi every sifu,

i want to ask, is there a difference between wira 1.5GL and 1.5GLi front suspension?

i own a 1.5GL where my bro own a 1.5GLi

i saw my bro front is higher than mine...
for example, for his car, i can put 4 fingers in the spacing between the tyre to the chassis. where mine only can fit 3 fingers.

but i notice some 1.5GL front, some same as mine, some the high rate is like 1.5GLi

what they change ? spring ? or absorber ? or add on rubber (but i dont prefer to add on rubber)...
