Theres a few that can be used all of which will allow you to go as low as you wish as they go under the driveshafts rather than over like your current one which i presume is rubbing hence why your reading this lol.
You can get some with bigger hoops and adjustable droplinks but from what ive read as of late they dont do the job aswell as the following ;
Mk4 Golf R32 - 1J0411305AF (23mm)
Mk4 Golf 4 motion - part number and size needed ....
Mk1 Audi tt - part number and size needed ......
Audi S3 - 1J0411305AA (19mm)
Skoda Octavia VRS - 1J0411305AD
Mk1 Seat Leon -
With all of the above you can use standard droplinks
You can also get aftermarket arbs that go under like the whiteline one but you could pick up the others off ebay for usually less than £50
the missing part numbers are welcome as i only done a quick search
