I realigned right after install....I Judy hit a very bad alignment lol!

That much torque could be twisting the swingarm and definitely could overload that type of toe arm. Is the LSD rated for the level of torque being transmitted through it? And what condition are the inner and outer swingarm bearings in?

[gzim335]

Alot of people are running the wavetrack with similar power levels.
I have both arms replaces with m3 arms kn the rear and gc toe arms.
The more i read the more im thinking my toe is out.
Do you guys recommend a toe setting or closer to zero the better?
I would think toe out woukd cause my rear steer and toe slightly in sjould help it go straiggt

You done anything with your diff bushings or a diff lock down?

no all bushings are stock,i ordered the solid sfb yesterday and going to get the e93 m3 rsb since ill have subframe down.
its a lot more dramatic than bushings flexing or getting squished,the rear of the car literaly goes from one lane to the other

I have the m3 rear sway bar and it made little difference in a straight line.

My car sounds like yours. It nearly switches lanes and wants to do 180 when I punch it. I want the m3 solid aluminums but I've heard they are harder to install than the delrin?

I'm also considering delrin or N spec for diff bushings. Currently I have the powerflex purple.

do you have adjustable toe arms?

[whosdady]

Yes, I have Megan blue adjustable toe arms, m3 upper links and m3 guide arms. I'm now in the process of upgrading my already upgraded suspension parts... I currently have yellow rear subframe bushings.

So what's the verdict? I'm torn between the AKG black (95A), powerflex black(95A), or solid aluminum. I want itoem quiet and not to feel harsh but lock it down. Will also be doing a wavetrac LSD, rear diff lockdown, new oem motor and trans mounts, and KW v2 coilovers.

I'm leaning to the AKG as they have some flex insulation vs vibration etc and the same rating as the Powerflex but cost $130 less.

Did you ever order one i'm in the same boat?

[Fundguy1]

I'm going with AKG black. Stiffer than m3 but a little give to hold off vibration and noise.

[FactorX81]

could you post pics of them and impressions? Are they all one piece or two pieces, do they have metal centers like powerflex?

You'll find them on this page.

[FactorX81]

Yeah those are the only pics I have seen I was hoping for better ones. The blacks don't look like they have metal inserts. I'm wondering how torqueing fasteners against these will work without inserts. wont the fasteners eventually work loose as they don't have something solid to be torqued against.

[Fundguy1]

Not sure. My installer says he uses those over piwerflex and gas had nothing but good results.

Yeah, I know, and they're two piece as well, kinda strange. The diff bushings and shock mounts clearly show metal inserts so I'd assumed they didn't include them in the pictures for some reason but since I didn't use them I never pinged them on it. They're very responsive via email, btw. I don't see how they can hold up to the torque and vibration without the inserts either, doesn't make sense.

Would like to hear what he says about this, AKG's other parts I've used are built like a freakin tank. Their DSSR could be classified as a blunt weapon fercryinoutloud... yow

[Fundguy1]

Well they're a bmw specific performance speed shop and they use these on all their track cars so I'll let you know. Rest of the build us sick too.
