In effort to lower my A speedster, any opinion of the Mono Leaf Spring like from Speedway Motors or Summit racing.
Personally I don't think they would look right. I assume there is some solution to making the clamps hold and also a way to keep them locked into the hole in the crossmember
That is not a mono leaf spring it is a replacement bottom leaf with reverse eyes. You still use the rest of the leafs.
The mono spring is thickist in the middle and thins out to the end and is intended to be used as just one spring with spacers at the center hole. That's my understanding.
There may be more knowledge/experience on modern modifications on other forums, like some hot rod community? But if the center spring clamp clamps it securely, and if you have good shock absorbers (since you'll loose the dampening from internal friction in the spring pack) and if you accept the non traditional look, then why not?
I would say you need add shocks to dampen it, as this what the spring pay of leave doese
Ok I see how it's made with the second photo. With shocks should work. Of course with a Model A, shocks were part of the design and really are needed. There have been a few people over the years that have talked about the handling of the same car with and with out shocks and the improvement having them made.

Some of the guys there are into the early hot rod stuff. Even with a speedster/track type body yours would still fall into that group esp with suspension questions.
