well, if you get the right tire your 18s shouldnt really be any taller or shorter than your 17s, or stock for that matter. they may be a tad taller or shorter, but basically the same. with the BAT kit you wont sit quite as low as you would with say eibachs, h&r's, etc. search around pic and vids a bit, people have been posting pics of different suspension set ups quite a bit in the last month or so (mainly goonz svt with his BAT setup, svtdriver??? with his koni and something (maybe eibach??, maybe not) setup) i think slingersvt had some pics up also.
