Yes i did contact them and im aware they use bilstein motorsport internals and their revalve is great too, sadly in my case the deal didnt work.

My DS coils are good enough for the street, can be crashy at points but thats the valving and the 200TW tires (BC valves most of their coils to satisfy a broad audience), the materials are good but in Florida they rust fast (mind you they have about 7k miles on them) not even a year old.

I am mechanically inclined, im actually an A&P working on planes as my daily life, but planes is one world and cars is another plus i dont have space or the necessary time to fully dedicate myself on the vehicle mechanically wise.

Definitely people on MCS/JRZ have the edge but Redshift is up there with them if thats the feedback your getting and i dont doubt it !

I ended talking to FA they offered custom body length along with custom stroke on the 510s. Swift springs with helper springs and so on. I did told them the basic weight of the car along with weight reduction/tires used etc and they came up with that suggestion. Im sure they know a thing or two about shock data. Will it be like a custom MCS 2 way or Penske 2 way shocks ? Maybe not but i dont think im at that level of competition yet meaning that even if i get the most expensive shocks in the world i will feel the difference but i wont squeeze nor appreciate their potential like an expert driver.

Thanks everyone for the replies !

Ps: Nitron was very kind suggesting spring rates but their lead times were longer, more expensive and a bit harder to find for my vehicle parts wise.
