If I put spacers under knuckles that is the same as extending the outer tie rod on thread of inner tie rod right?

under knuckles? no you space the inner tie rod between the inner tie rod and the steering rack. It lengthens the inner tie rod so you don't need to use a longer tie rod and get more steering angle.

I runned 7mm spacers when i had e36 LCA's, so practically now when I have e46LCA's and e9x inners I don't need spacers?

do you have pictures of the spacers?

You mean the drifting extra angle spacers right? Yes you want those. You need the spacers. Use the spacers and a regular E36 inner and outer tie rod. I don't think you need e90 anything.

I don't know, it is too short with e36 inners...

I have shortened e9x inners for 1.5cm and put it on without spacers under knuckle and everything fits great..

Now is the time to set up wonderful wheel alignment. Do you know how to set it up? how much toe would be the best? 5-7mm on each side? i have -6.5 camber on the front now (measured by iphone clinometer tool).. I don't know how much caster i have because i don't have fenders on my car so I can se shit

there's an Iphone app that measures camber?! WHERE?! I must find one for my droid.

What do you do with the car? Most auto racing, start with 0 toe and toe out as needed. Toe settings is more how you like your car than what is "correct".

Can you post pictures of your E9x tie rod setup so we can use it to educate others? THANKS!

Car is ONLY for drift purpose... App for iphone which measures camber is called Clinometer, it uses flat straight piece of wood/metal which you put on the rims and measure camber..

Here is that huge camber and rod, you see that it is a bit too long, so I shortened them a bit and now it is great..

start at 0. add toe out as needed. Toe is preference not law.

I found out that rack spacers are a MUST, I will go with 7 or 8mm, because it is not the same if you put spacers under knuckles or if you loosen outer tie rod...
7mm would give me plenty of lock , and with this camber of 6.5 degrees it would be niiiiceee :P, toe will be out half of degree on each side

They aren't a must. They can be useful or they can be a crutch for a bad driver. Just remember that.

If you want more lock, you need them, if you put e46 arms without spacers, what did you got?, only camber

Very valid. E46 arms give you, more track width, more space to add meat on your tires, more room for that extra angle. Also camber and depending on how you install it, more caster too.

I understand that if you want more lock, you need them (or a moded knuckle kit). But it's the same as starting with 500whp vs 100whp. IMO you learn more with the 100whp. Once you learn it, then up power. Same with angle.
