i need a new suspension and i think that i'm going to order the zx2 struts and springs from oem.....and i just want to double check....i read the installation guide and it said the rear were installed just like the pro suspension...but the fronts need a bigger hole cut...is this the only mod to make the zx2 suspension fit the pro?...i need to know b/c i won't be installing it myself...and i want to know how much labour will need to go into the instal....
