Well, I'm not sure on this one, but I thought that the only real difference between the RE and RA was that the RE was a more track tuned suspension using stiffer spring rates, and had 32 adjusments rather than the 16 on the RA, but again, I really didn't look much into it, so I could be wrong....

I the case of suspension, especially when it comes to the steet, you really don't need to know a heck of a lot, just what works for you, unless you really want to impress someone at your next cocktail party(jk). You really don't need a really expensive suspension setup order to get really good handling on the street. Although the Zeal, Buddy Club, etc. are all really great coilover setups, in all realistic terms if you don't go to the track a pretty fair amount(monthly), a Mugen 26mm rear sway bar at like $375 is more than you need and a fraction of the cost. That alone will for the most part correct a lot of the "plowing" and understeer associated with Hondas. But, really, to justify spending over a thousand bucks on coilovers that, in all honesty won't be all that wildly phenominal on the street, would be nuts. Coilovers shine on the track, but on the street, may not accomplish what you think they will.

you might be surprised, your car's limits on the streets, will probably far overpower you, even with stock suspension. My advice is, improve driver, then, improve car. And, if you don't go to the track, likely to not, you're probably not getting in the requisite practice to be a superior driver, on or off the street. Learn the basics; how to heal-toe, how to trail brake, how to correct over/understeer, where to apex a turn, etc... Once you've gotten really good at that, and feel that your suspension is insufficient for your level of driving, then move on to improving your car. On stock suspension we've managed to win quite a number of Touring class SCCA events, and in fact match the lap times of some pretty well modded Integras in different classes.

Consider that, more isn't necesarily better, often, all it is, is more......
