HAs dont appear to be made for the 7. but to answer the original questions:

TEIN Type RA has been designed for advanced circuit racing and street use for experienced drivers.
It incorporates a newly designed mono-tube structure, which allows for maximum road handling and driving stability for all type of situations.
This product has been developed from a huge background of TEIN motor sports activities (such as the World Rally Championship,
N1 and endurance racing).

* Mono-tube design for maximum performance.
* Constructed of A7050 aluminum for lightweight (on certain applications).
* Strut type suspension has an inverted steel shock absorber for durability.
* 16 levels of damping force adjustment (compression and rebound together).
* Ride height adjustable.
* Exclusive designed pillow ball upper mount for optimize performance.
* Available for overhaul.

HA:
"A" stands for the acceleration of your driving pleasure.
The expansion / contraction function is built in
(16 level click attached) Type HA Damper
to make your imaginative driving come true.
In addition to the basic function of the Type HR Damper, we have added damping level adjustments. The variety of so much different damping effect is able to cover all setting range needed from soft (a degree of your vehicle's original damper) to hard (stiff as the N1 endurance race car) in 16 levels.
All products meet Japanese car regulations.
Type HA can be disassembled so that dampers can be overhauled and settings changed. A different spring rate for the HA damper is also available on request with recommendatery spec.
All dampers fit directly into the original upper mount. However, we offer an up grade upper mount kit which replaces the rubber bush with a pillow ball (spherical bearing).

This product comes with an original gauge for the minimum 90mm height, and a specialized manual.
Helper springs are available to stop spring rattle.
The 16 level click dialed expansion / contraction function is built in its system.
We also offer a value kit which comes in a set with the pillow ball upper mount. The spring seats and seat locks are light weight aluminum die - cast products.
16 Level Damping Effect Characterized Diagram (S13, Ft expansion)
Type HA Damper has an adjustable function for its expansion / contraction level so that the driver can select his / her own choice of damping force needed. The varieties of different levels of damping force covers wide setting range from that of the original shock absorbers to the level of race cars. A minute orifice which characterizes the suspension of the vehicle is fully controlled by the special formed needle with high response at steering, braking, and throttle control.
Furthermore, the damping effect reacts linearly to the adjusting dial. It is valid for all 16 levels.
