but with the stuff that the average consumer will buy - basics, super streets, flex, etc. - there is more to be had. You'd be paying for the name more than anything IMO.
The Flex has adjustable strut length and spring preload. Those things just can't be be with anything but a full coilover. The added cost of the full coilover isn't so much the name that you pay for, it's all of the extra features. Comparison just for fun:
Tein Flex: $1,700
- Adjustable preload
- Adjustable ride height via threaded strut body (doesn't reduce strut travel)
- Adjustable compression and rebound damping
- Adjustable upper camber plates with pillow ball mounts
Ground Control: $300
-Adjustable ride height via spring perch (reduces strut travel)
4 Koni Yellow: $550
- Adjustable rebound damping only (no threaded body for ride height control without sacrificing travel)
4 Tein Adjustable Pillow Ball Mounts- $320
Now you're up to $1170 and you still missing features that just cannot be had with this setup. You still only have rebound adjustability, you still can't lower the car without sacrificing strut travel and you don't have the option for spring preload. You also don't have the larger strut design that allows for larger pistons, valving and more fluid capacity which make them stronger and have better heat dissaption. Considering the features available with the full coilover, it's not a bad price.
