I'm going to buy...

Moog-K80812 ..... is THAT the poly bushing from Moog you are talking about? Because it does nto say poly in the description that can see...

Also... has ANYONE installed sway bar lateral locks before? Like this?

http://www.moog-suspension-parts.com/kll122

ALSO... I'm going to go with Moog K200787 and K80778 bushings for a stock control arm also K5331 ball joint.. I called the Moog Tech line and to my surprise they could not guarantee that if I bought CK620676 that it would include the problem solver bushings!? WHat? Something about old stock maybe being mixed in with new stock... Anyway so I guess I have to buy everything separate to guarantee what I get.

You can see from the pic I posted my sway bar needs replaced too its rusty on the inside. I suppose staying with the OEM sway bar is the right choice I've heard about going thicker and mounting to the LCA instead of the strut but I don't often corner hard so I don't think a thicker bar will help... maybe in the rear a thicker bar if one exists to reduce squatting under hard acceleration?

For the most part my car now does less than 10,000 KM per year(summer only) and won't often see rain if at all so keeping the car clean should be helpful in prolonging life of these expensive components... I'm looking to maximize the suspension capabiliteis of my GXP because of the power it puts out plus just to do it right... going to buy the BMR rear suspension setup too BTW...

any input from other members who already went down this road would be much appreciated!

That is the correct bushing,you will want to replace the sway bar end links as well. No way I would just replace the bushings in your control arm, too much work and it is already rusted most likely.. I did the problem solver ball socket and problem solver polys in new A/C Delco control arms as well as the big GMPP bar, night and day handling difference.

BTW Parkave has those big control arms, you may want to message him for more info. He has a killer suspension.

that thread link you sent..... the control arm looks tubular!? You say its ACDelco??? What is the part number?

So far I can only find $500 ZZP tubular front lower control arms, and its not even a direct stock fit it requires me to get a difference sway bar that attaches to that control arm... perhaps the thicker GMPP one...

do you have part numbers for any of this by chance?

What is the advantage of a tubular control arm as opposed to a stock flat one that I install better bushings in anyway?

So you are saying I should go GMPP thicker back and get a lower control arm that has the connection for a sway bar(some have that connection some don't)

Mine are not tubular, but the pic of Parkave's control arm is in the same post. Order the problem solver control arms from amazon or Rock Auto, if they do not come with the correct parts send them back. It will not come with K200787, those have to be purchased and installed later if you want those. I went with the Delco because I got them new off a member of another board for 40 bucks each, and the Moog didnt include the poly rear or the ball socket bushing anyway so the only real benefit was the better ball joint.

Because I'm in Canada and depending on where I order from returning could be problematic. I'd prefer to pay if I have to a bit more and order everything separate so I can control what I get exactly..

I called the Moog tech line that's what I wanted to know was if I buy the Problem Solver LCA does it come with the better bushing K200787 ... he wasn't sure believe it or not and you say it does not so then what is the advantage of buying the Moog problem solver LCA? Nothing other than the ball joint as you say right?

I should just get whichever LCA is the cheapest then right? And then install the better Moog bushings... but If I go with the thicker GMPP bar and mount to the LCA then what poly sway bushings do I use because K80812 is for the regular size sway bar... the GMPP is like 34mm... do they even make a poly for this bar??

http://zzperformance.com/3800/suspen...-sway-bar.html

that is the one I need then right? I want poly on the bushings though...

Thats the bar I got, only I bought it off ebay new by itself because I knew I wanted to upgrade to poly bushings and those are not. Lots of part numbers for the 34mm bar, I used 25861196 and paid 56 bucks shipped. Poly bushings for that bar are K80815, endlinks I used are K5342, but there is also K700527. That bar must be used with the correct lower control arm. I used 45D3358(19240665) and 45D3359(19240666) A/C Delco but Moog may be better.

Since I have never seen those, I would think they are unnecessary lol.

To me, that looks like snake oil. I doubt that would really help at all.

Here you go, one on each side of the bushing, Harbor Freight 2 bucks lol.
