It used to be that front springs were a one time purchase without much thought given to replacement. Moroso was the only choice forever. Observant racers have tried some alternatives that were much better than the typical spring that required cutting and often ended up too stiff. Different cars have different needs. While some cars have off of the shelf items that work, there are many cars out there that would benefit from a custom spring.
We tried different springs and found a set that was awesome for our car, but difficult to fit yes. I also don't expect them to last forever. Fresh springs of the correct size spring rate, etc have a place in the market. More racers are figuring this out, but not all racers have an alternative. If we can order custom springs at a reasonable cost, I think there will be a growing market.
It will require testing. Some people want someone else to figure their cars out for them on the internet and never test. Then they complain when others are faster.....
