What is your interest in having a bolt-on A-Arm front suspension???

[Shadowbug]

a bolt on front suspension would be a great product idea, but from the perspective of ideals, the frame horn has to go, a completely new chassis would be even better.

Keeping the frame horn limits the length iof your A arms, which is not terrible, just limiting.

the ability to use Longer bottom a-arms make dialing in your suspension geomery/design much better, you have less compromise, you can have reduced bumpsteer, ideal camber gain, and a well located and stable roll center, you don't have to choose one.

if you were doing a 1 off custom chassis the 928 spindle would be a nice piece of kit. But for a bolt on front suspension, stick with the beetle spindle
it worked well with the paralell trailing arm suspension, so it will translate well to a paralell eqyual lenght A-arm setup, or even an paralell non-equal length suspension.
