I'm looking for a J Spec FD and the import sights I'm looking at have all of these different type designations. I assume that they are various packages, with R and R2 possibly being the racing or Hi performance modles. Also what is the story about the R1's I heard those are the ones you want to grab if your looking for the best performer. I will be in Japan for the next 3 years so I plan on picking up a FD there. Just trying to do the home work on what to look for.

 

there is no R1 and R2 in Japan.
here is what u need:

hope thats helps.

 

R1 were made in 93.
They changed the name to R2 for the 94-95.

 

There is no performance difference between the R1, R2, or Touring issue cars.

 

correction... there is a diff. on the r2 mazda changed the suspension. it rides a little softer then the r1's.

both have 2 oil coolers.

 

How much horsepower does different springs add? You tell me.

Also, since these cars are going on ten years old hear in the states there is a good chance that the stock suspension is either bad or has already been changed out on any car that you will find on the market.

I feel that for someone shopping for a seven today on the used market this is really a mute point.

 

LOL you said no difference in PREFORMANCE!

suspension is a preformance product!

you wont take a turn at 60mph with every car!

My suspension is stock and its still fine! I have a 1994 rx7. still handles GREAT!
