Tein is notorious for making very street unfriendly coilovers that tend to rust. This new generation seems to have addressed some of their damning weaknesses. I had Tein SS on my previous car for 7 years (no rust, no clunking, etc) and they performed beautifully so I have a soft spot for them despite all the negativity :lol:

Great cost effective system is the best way to put it.
The StreetFlex has replaced the old Flex system by offering a better product at a lower cost.
The new StreetFlex offers a 200% wider adjustment range compared to the outgoing flex system. They also change the top hats to steel instead of aluminum to bring cost down, and added a tougher coating to the body to prevent corrosion.

This post should help you out a bit, 1st part is about the new EDFC Active, 2nd post is about the New Street Flex

I've been scouring the internet for reviews and they did get a pretty good reception amongst the BRZ/FRS crowd :tup:

I had a pair on my old civic before the sti, and they worked very well. I had on minor leak on one strut and was covered under warranty and taken car of fast and efficient, with fast delivery of parts from japan. Had a great experience with them and would definitely choose another pair for the sti.

i have the monoflex coils on my sti. at 550/450 rates. i honestly expected a much rougher ride than it has. car handles great on track and autocross and i drive it frequently on the road without changing damping settings at all. i cant imagine the street flex being rougher.

good stuff :tup:
So I ended getting a fantastic deal on these coilovers with the Black Friday Sale from RSD :tup: My old BC racing coilovers had 70k miles on them so I felt it was an appropriate time to replace them. I've now logged 5000 miles on the Tein Street Flex coilovers and I must say I am thoroughly impressed with them.

The build quality is flawless without a blemish and operate without any creaking/clunking/harshness. Tein has claimed that they improved the valving of their coilovers with the Tein Street Flex tremendously and I can certainly attest to that. I've set my coilovers in the middle setting for daily driving and I've had up to 4 additional people in my car without rubbing and all of them pointed out comfortable the ride is, this is coming from both sexes :lol:

When I want to do some spirited driving alone, these coilovers offer sensational stability and instantaneous steering response, with the 15:1 steering rack of course lol (still VERY good). The dampening on these coilovers are superb where the car stays completely composed over bumps in the roads and absorbs them like a champ even traveling through atrocious D.C. roads.

I highly recommend these coilovers for people wanting somewhere in between BC Racing and K&W V3. I can't say anything that really makes them stand out with other mid-level coilovers like Fortune Auto or Feal except that I am very satisfied with the Tein Type Flex. Here is a video of me driving through the crappy/bumpy streets of Georgetown to get a sense of how these coilovers handle bumps:
