S1's dont come with adjustable tca's though. Just a caster adjustable arb. Gus worth doing though as i'm doing it at the moment but if you want camber adjustability you'll need MEF tca's. You need to drill extra holes, have a gear box with the front mount holes such as a mk3/5 and the rear gear box mount. Rs1600i arb set ups are better though if you can find one
