difference in eibach springs pro kit NA vs TII
 

the NA pro kit's model number is 5513.140<---have this one
the TII pro kit's model number is 5520.140

the specs seems to be the same
Front Rear
0.8 in 0.8 in

what is the actual difference in the two models, if anyone can help me out.

i was initially going to put the springs on my 86 GXL but now i have a TII in the works. is there any problems of using the NA version springs on a TII?

dont think so
the T2 ones might be a bit harder to help with the extra weight

alright, that makes sense though because of the weight difference. thanks.
