You definitely want to do the EZ's out of those two options.

If you still don't know much about coilover setup i suggest reading up on suspension set ups and figure out the pros and con's of the different coilover brands people are using. I have heard a lot of good things from the Megan EZ's

out of those two then i would suggest the megan. also look for CXracing as well. i have heard good things from people in the IS world that is using them.
