just curious simon, but are you plannin on using the s14 suspension? are you modding your strut towers to suit, from my measurements, tryin to squeze the struts into the factory 86 position, throws the geometry way out of wack, and will end up in huge camber, though i don't know too much bout suspension, but i have been advised by my suspension bloke to try and mod the towers to suit, measured against an s14 there is just enough room for them to be mounted in the factory s14 position in an 86, but involves a fair wack of work to the strut towers.
