I have had them both, forst the sportlines...and now pro-kits. i like the pro-kits MUCH better. ride quality to me is no contest, the pro-kits are much better. i can tell it doesnt drop it quite as much, but everyone else cant tell any difference. i scraped a lot with the sportlines. when i put my pro-kits in, i was blown away by the difference. my vote goes to getting the pro-kits, no question. either way though, id get some aftermarket struts. i have Tokico N/A's and i love them.
