Well, After talking with Odi and Adas from FEAL I placed my order for the FEAL 441 Coilover. Both guys are super knowledgeable and really helped answer all my questions. Any company with service like this is where I'm going to take my business. There are a lot of topics that I covered with both guys and I think I'll do a good write up on these to talk more on why I made this decision on top of the product review.
I did talk to both guys about the re-valve for GR struts/shocks, but it appears they only do the front struts now. They didn't like the results of the rear shocks and turns out that the 441's were really a superior product for a very competitive price. So anyone looking to do the re-valve, you might have to wait for them to do some more R&D for the rear assembly.
I went with the standard 8k/8k spring rates and Odi will have the everything pretty much pre-set for me. Can't wait to get them installed!
