that may work...but slotting may weaken it, if you could fold a lip or similar to keep strength..??

sloting the top ball joint pulls the wheel in closer tot he shock.. better to slot the bottom contorl arm mounting points and push the lower arm out.. same result, wider track and wont go as close to the shock as it would if u were to move the balljoint in :wink:

masssive efort cuting and shutting thelower arm when sloting the lower bolt mounts does the same thing :?

if slotting is not pushing it out enough then just drill a new hole 20-30mm out on each side and move the arm to that point :?:

to get 100mm (50mm on each side) u would only need to slot the lower mounting holes by (apporxamatly) 20mm... possiblty even less.. by the time u multiply the distance u move it out by the distance from the point the wheel pivots on to the bottom of the wheel where it touches the gorund (and all that :lol: )

someone smart can work it out to be exact :lol:

This will increase camber but you walso want to increse the caster to a certain degree by slotting the top balljoint rearwards! (draw a line throught the top and bottom balljoints and you have the caster angle)

but your not pushing the arms out or in your moving them towards the front of the car or towards the rear of the car.

He's saying slot the holes the other way which I can't see working as the balljoint would end up hitting the edge of the arm and the mount holes would overlap the big hole.
Dunno why you would bother, you could just move the whole upper arm backwards at the crossmember.

Mooving it out will move it backwards or forwards.


The mounting points are different distances from the centre line of the vehicle.

i'd rather move the whole top arm than the ball joint. you do that by changing the length of the top bolt tube.

Camber increase is done by pushing lower arm out.
Why would a drifter need more lock? if so just fit a bloody old kingswood assembly in....
Increasing the front track increase oversteer.
Increasing the rear track increases understeer.

The gemini series runs a standard lock 3.9 turns lok to lock.

Anyway back to work.
