All due respect to Ftuned but don't waste your time with something that's not easily accessible to you. Also their aftermarket service has gotten worse over the years. I've gotten the negative end of their response in my old 4k++ setup so I'll never go back to them ever again. Find a brand that you have easy access to (after sales service, servicing, if you need to change spring rates easily can access, etc) and go buy that brand.
The good thing about Premium, Titan, HWL, Ftuned, RDS and all these specialized shocks companies is you can tune the suspension to the way you like it. The bad thing about these companies is the same thing - the tuners will sometimes insist they are right and tune it the way they want it because they claim to have "years of experience on the track and on the road". If you go there INSIST on a test drive on a similar car to determine what you want from the suspension cuz everyones butt-dyno is different. If you can't test drive then don't buy immediately cuz it's not going to be a cheap purchase and it's also going to last you a long time so you'll have to live with whatever you buy good or bad.
I've sat in cars with all these brands except Premium (but I suspect it's similar to Titan) and I've experienced bad as well as good combos for all these brands. The only brand I've never seen "bad" before is Ohlins - On a FD2R, BMW M3, all are magnificent. But their price also magnificent.
