If that's a delivered price, it's pretty good (I scope used stuff often since I can't afford new).
I only know about Sportlines on SN95's (I have a Prokit on the '94). For that application, I really dig the Prokit. Even so, I have to drive up on a 2X4 before I can jack the car up. I drag cats on speedbumps too.
Sportlines look sick but like the other guys said, if you have curb or speedbump concerns, it could be an issue. Poly isolators help a little but not much.
You will likely want some decent dampers to go with the relatively stiff springs (with either the PK or SL's)
I know that doesnt help much.............
Good luck.
