Hi have you got any pics of the bottom arms fitted to a s13 as i am not to sure were the bit at the end were the ball joint used to fit (yes i am that thick)
Its the bit under the carrier i am not to sure about.
On an S13 make the lower arms as short as possible to start with (this is about 10mm longer than S13 stock). The tension rod you can't really measure, just set it so the wheel looks like it's in the middle of the arch and go for a full geometry setup .
