Any insights, or personal experience?
Strut wear and tear is more related to spring rates. I imagine the reason why Dinan is using the factory structs up front is because they are already robust enough for the new springs. Dinan is very careful like that, especially since they are providing up to 4 years of warranty. I would not worry. They do a lot of R&D to ensure safety.
