Anti lift kit would be set of bushes for lower control arm. Something like this: https://www.kmsmotorsport.com/index.php?route=product/product&product_id=2703 Well this is something to consider if you are making a track car same as mentioned "sport" dogbone bushes/inserts. Anyway for comfort driving just don't put any inserts on your car. Check your OEM dogebone bushes and if they are broken(cracked and rubber usually) just order new set of 2(upper and lower)... It will be hell to replace just bushes but it is only proper thing for comfort driving I'am afraid :(

PU inserts fills the voids from dogbone bushes and side effect of that is reducement of engine movement which is better explained on this 034 Motorspor video: But imho PU insert works in even more extreme way than 034 with probably even less movement than on this video. So PU and 034 significantly eliminate Drivetrain slop or drivetrain movement and bushing deflection because they are filling large voids that are made for NVH reduction. As a positive side effect you(we) will certainly have better starts or launch than the same car without it plus improved gear shifting feeling (you can really feel it no joke here) so at same time also improves car stability(downshifting before hard turn definitely noticeable) because whole car is significantly firmer. But negative side effect is only one but big as a house and that is NVH at idle... Now if someone can live with it and often drives in "lap timer discover media mode" simple dogbone insert will certainly improve his lap-time. What can help(it helped me) is raising idle speed on 950 rpm's but I am still not satisfied... So If someone found the way how to get rid of NVH with installed dogbone insert or similar dogbone stuff please put your findings here.

Yes... I agree now... Poly has advantage while driving the car but "IDLE" kills that good driving I am all into Ears now... What is anti-lift kit and where I can order one? We must be realistic here. It has some benefits like better launch starts by elimination of wheel hop, crisper gear shifting wit MT transmission cars, car feels more solid while driving but man! Idle is OMG 👎

I agree that NVH comming out of Powerflex PU Red insert is terrible... But I still have it installed after more than 2000 miles and somewhat hoping that NVH will reduce 🤦 . So do you still have 034 installed?

I have registered on briskoda to reply into this topic... Test subject VW Passat B8 2.0 tdi & Powerflex Red Dog Bone insert... 1. I am angry at Powerflex. Why? They sell this red insert with instructions that we should change original stretch bolt to new one!? Ok! Great! Just Great! Why don't you offer mentioned bolt with your Dogbone insert set? Why I have to spend additional time(finding, ordering, driving etc.) to get one screw? Ok I've bought OEM bolt so lets go next... 2. Don't start unscrewing mentioned dogbone stretch bolt before you have pushed red insert into voids! Once when you've pushed the insert(silicone spray, silicone grease) you can start loosening the bolt(not easy, lot of force here) 3. I was aware that NVH will occur; but boy! This is teeth rattling on the idle so I used VCDS to raise idle speed on 950 rpm's to smooth up things a bit... Now I saw at leat 5 posts on google various web sites claiming that NVH will dissapear after 1000 miles of break in period time?! 4. After 2000 miles this insert acts same as the first day... So for me that really proves that Powerflex has high quality product that does not require break in period to settle down! But not for everyone! 5. I would not recommend this in a daily driving car... Better car starts without wheel hop, crisper gear changes are worthless when you have terrible Noise, Vibration and Harshness or NVH at idle! Especially if you live in a Town or City... I wonder weather Powerflex engineers test their product after designin it? Make us something that will work equal way as yor red dogbone insert but without NVH!
