    Although I would LOVE for this to work, I'm not going to hold my breath. It would be too convenient for it to work out for us.

    Re: Unsprung Weight Reduction: 09-13 Forged Aluminum Knuckle?

    Upon initial inspection, it looks like the upper arm mount is plug and play. I noticed the same holes in roughly the same location. I weighed the knuckle and it came in at 5.3kg. I forgot to weigh the upper arm mount but will weigh it when i get the other side later on.

    Will weigh the stock knuckle once i have it removed from the car.

    Things you will need to buy from Luke are #1, #9, and #10 thus far.

    I will update you all once i know which other parts you will need...

    Re: Unsprung Weight Reduction: 09-13 Forged Aluminum Knuckle?

    I weighed the original knuckle and it came in at 5.950kg, thats 650g heavier than the new one...Talk about diminishing returns. You need to drop about a grand for two pounds of weight...

    Have to order the lower arm as well to fit the new knuckle.

    As a dry fit, i have positive camber, but it all depends if the new lower arm sticks out more than the OEM. Also the new upper arm sweeps the top of the knuckle about an inch backwards givin it more negative caster.

    So before you go for this, you need to order the upper arm, knuckle, new V2 calipers, and lower arm. Unless you are plannin to upgrade to the new V2, i wouldnt recommend this upgrade...

    Re: Unsprung Weight Reduction: 09-13 Forged Aluminum Knuckle?

    If the CTS-V and CTS control arms are the same, we should be able to pick up all three pieces for about $300 per side (1.43 lbs reduction per side, assuming the arms are the same weight). Out of curiosity, did you only get the knuckle, or did you order the control arms as well? If you didn't get the latter, I'll look into ordering used pieces and do some test fitting of my own.

    I'm curious to know whether there would be more clearance from the inner side of our wheels. My thought would be to run a larger front wheel with more backspace/offset.

    Re: Unsprung Weight Reduction: 09-13 Forged Aluminum Knuckle?

    I am already running a spacer on my wheels for i forgot to add it to my new offset. I am also runnin the GMPP longer studs so i am not too worried about pushing it out...

    I am a little worried about the caster being further back, it may interfere with the steering or upward movement. Will have to wait another week for the part to arrive so i may fully try everythin out.

    The idea is sound, and you will have a slight issue with the rear "horizontal" bolt, mine was tight during tightening, but the others went in with no issues...

    I received the part to complete this mod.

    First problem, you need a 18mm spacer for the rear bolt to be snug. Am havin my machine shop create two for me. The problem with a standard spacer is it may slip when tightened down. You need to create grip notches so when you tighten it down it holds snugly and doesnt move under pressure...

    Second problem, the sway bar end links may need to be changed for instead of holdin onto the bottom arm it holds onto the knuckle. Will see how much longer they need to be...

    The shock is pressed back a bit as well though i dont see that as a problem. But its a concern that should be noted...

    The new lower arm is 49mm higher for the bushings which may allow a lower stance with no negative effect on the arm position.

    Will report my findings as they come to light

    Can you provide a picture of the end link issue? That should be the easiest to solve, given the wide selection of aftermarket parts.

    I'm mostly concerned about "pressing back" the shock. What do you mean? Are you saying that the mounting points are located further inboard?
