why such big wheels? you really should stick to 14s or 15s on a ke70, unless you are building a show car or something. Youve got no chance of making them fit without serious modification, not to mention the legality of it.
15x6.5+23 on s13 gear really only just fit on my car with fairly comprehensively rolled front guards. yours will stick out a further 52mm than this. S13 front control arms are miles too long on ke70. I battled with it for years. R31 is a bit shorter and works better.
