- In this video we show you the process to lower the rear of a classic beetle equipped with an independent rear suspension (IRS). You can do this with basic hand tools and at very little cost.
Results may vary depending on how many splines you move and also the condition and type of shocks you have.
Final shots of the car footage were lost, bummer!
The VW Beetle in this video is a 1970 Classic Beetle.
Here is a handy chart showing the amount of splines vs how low:

Agree - have viewed many; your video was absolutely the best!
Thanks for the kind words! I have some more coming out just need to find time. I'm glad they may help👍
One of the best lowering videos I have seen.
Hey thanks a lot Junior! I appreciate that!
That was the best video I have watched for IRS torsion bar work! It will make my job of replacing bushings much easier now. Thanks! But I saw another video where they said it wasn't needed to remove axle from hub? Either way, fantastic video, very detailed, just what I needed!
Hey, thanks! I prefer to unabolt the outer CV since it does not take long and you are not fighting with the axel during the rest of the work. Good luck on yours and remember to take pics and mark you stock angle before removing the spring plate if you want to return it to the same spot.
This is the one I needed. Thanks!
Right on!👍👍
So you just go up 1 space on the inner spline ?? Dont have to adjust the outer side??
Thanks for the question, The indexing of the splines will dictate the height you get. The inner and outer splines are different. The inner and outer have a different number of splines and therefore if you move the arm on the outer spline position it will be a different outcome vs not moving the arm on the outer and only moving the position of the inner where it goes into the chassis.
Here is a link with some info regarding the effects you get inner vs outer

Keep in mind this can also vary a little depending on the condition of your torsion arms.
You may do it 1-2 times before you get the height you are looking for. Take your time and mark things for reference in case you need to go back to the way it was.
Good luck!
Off subject question. Do you know what trim rings you have on your wheels?
No, they were already on the car when it was purchased , sorry.
how many inches was this drop
Thanks for the question! We did1 inner sp’ine which should give about 6cm or approx 2.3”, which is close the what we got, I would say it was closer to 2.4”. Weight in the car and how strong your tortionnaire bars still are also shock absorber type and condition can all vary the final heights slight bit. If you google Vw rear torsion bar height you will find charts that show you height vs spline setting. Hope this helps!
