Sportlines. They're very good. I had them on my 172 and was very happy with them.
Don't know anybody who has a bad word to say about them.
Me. I thought standard springs were better than sportlines.
Depends what you want the car for Laura. I found it handled best with standard springs in, and tried a fair few types of coilovers and spring at my expense. Its most fun to drive, its nimble, and it puts the biggest smile on your face.
For cheap looks apex (yes theyre crashy, but if you dont drive on the limit on b roads and want a spring that looks good theyre fine), for cs type approval but similar ride to apex, barely changed ride height and woolly steering sportlines, to do it properly fk's/ h&r's/ kws/ ast's/ ledas (if you can get hold of a set).
Ive not tried the cheapy coilovers ktec were doing so unable to comment on those.
