I'd like to reiterate that the outlaw caliper bolts to the s30 strut, and I think it'll bolt to the s130, all you gotta do is measure the distance between your mounting holes, should be 3.5 center to center
juan at jsk (havn't heard from him in quite a while) makes a kit for using the wilwood calipers, if he's still making them I believe he stopped quite a while back
terry (I seem to recll that being hie name) makes the outlaw kitshttp://
www.outlawbrakes.com/brakes.htmland the kit I was speaking of uses the 12.19 x .81 vented rotor, you can get them by brembo, wilwood outlaw or any race brake manufacturer, he sells the hats for $250 a pair, but the 240, 280 and the 0280zx all use different thickness hubs so you'll want to specify what hud you plan on using to be sure that the hat is the right thickness
wilwood does sell hats and rotors that'll work but but might not be the right offset for the outlaw caliper, most people running wilwood hats and rotors are also running wilwood calipers, I seem to recall a total of about $1500 to buy all the parts form a seller that sells the pieces at a good price, the bad news is you have to measure and figure ti all otu and look through their catalogs to find the right part numbers for your application and hope you got it all right
