It will not be helping with the fact that you have it so low and as a result not much spring tension on the torsion bars.
If you look at all the good Beetle drag cars like Dave Butlers AKA Dangerous's you will see that they sit at close to standard height.
I would also be checking that if you are going to keep it that low as to whether you have short shockies plus also fitting a front and rear gearbox
straps .
And last but not least REFIT your bump stops before you damage the spring plates and shocky towers.
Don't let body work get in the way of real suspension travel

Provided your tranny mounts are in good shape (probably not NOW),
there are a few ways to give better support to the forks.
The bar under the engine is the easiest but my LEAST FAVOURITE.
This is because it is hard on the rear body work of the car and can get in the way
of the ground, and various engine components and maintenence.
If you want to keep your soft mounts, a brace from the forks to the shock towers
(and also between them) seems to work well.
Pagey made some out of old VW tie rods..easy and economical.
My car has solid gearbox mounts and the forks are tied into the roll cage.
There is another type of axle hop caused by the car hitting the bumpstop TOO hard
and this unloads the tyre.
A bit of extra space at the bump stop and a higher spring rate
can make a huge difference here.
My guess is that you need to look at the mounts and fork support.
Oh, and the car looks cool that low but it will suffer from lack of car performance,
due to small tyre contact(this is why it can wheel spin),
and your side covers and axles could do with a bit of room to move(OUCH!).

....and then you can get lower.
See if you can hunt out an old camber compensator.

You need the Axle Hopper-stopper (patent pending)
Insert an axle hopper-stopper under your accelerator pedal to instantly stop excessive acceleration which is the prime cause of axle hop.
Now widely available through your local Bunnings and selected hardware stores.

also useful for holding up engines, cars, boats and houses, as well as throwing at frustrating political regimes. :P
