■About LEGACY RS type R & type RA

There may be many people who do not know first generation Legacy RS "typeR" & "typeRA"

●RS-R
The debut of first Legacy was the end of January, 1989 (February 1 release). The turbo car was only sedan RS of 5MT at first.
In October, the same year, RS-R is added in accordance with a debut of GT which is a turbo car of a wagon (and 4AT version of sedan RS).
It is written with "a basic grade model of RS which is suitable as the material of a competition car for motor sports" and a new car commentary book.

●RS-RA
 In November, '89 (December 1 release), pure competition car base for motor sports, RS-RA of a STi tune appear.Therefore the position of RS-R became considerably vague debut two months later.
It is written with a new car commentary book with "the order production RA memory model that executed engine fine-tuning same as the challenge car that 100000km speed records RS-R in a base."

RA seems to mean, 100000km speed record challenge "RECORD ATTEMPT" instead of RA of Rally.
(There is an opinion that RA means "Race groupA")

RS-RA put a fine tune to a rally and a dirt trial competition to be based on RS-R more.

As for the engine, forging piston and high resist pressure connecting rod metal are built in, and, as for the intake port and exhaust port, it is revised gap and polished up.
A crankshaft and the flywheel which got of balance are mounted the car with.If it is a beginner's class level, suspension is strengthened to the rank who can participate as it is.Variable ratio power steering is important, too.As for this, the steering gear ratio becomes quick.

Without close ratio transmission, it was announced as 100-limited model at first.Actually, seem to have continued job-order production of 20 monthly productions.
Long-awaited close ratio transmission was carried than a B type from May, '90, and increased with a catalogue model.

Engine specifications do not change from a latter period model C type, but ECU becomes 16bit, and a torque up in middle low rev .(be said by an emission control that became mild) and continued to exist to the last D type, and handed over a duty of RA of legacy to impreza WRX-RA with full model change-over, and the grade of RA disappeared from legacy.

■CHASSIS
●RS-R

  • Hardened coil spring,damper and bush(equal with STi product)
    (except rear differential mount, trailing arm rear side, a stabilizer)
  • Adoption of three spoke steering MOMO "COBRA"
  • Adoption of an advan "GROVA" high grip tire
  • The abolition of steering assist power change over switch

●RS-RA
 Difference with RS-R

  • A variable quick power steering
     gear ratio  In going straight:15
     (over all)  In full steering :13
  • Hardened coil spring、 damper
    The level that can just participate in an intermediate class rally
