The Comptech Pro Shochs are the best you can buy and they work the best as well!. The Ra and the yellow Koni are street stuff,when I installed the the Pro Shocks it was a new car and was a 100% inprovement over the yellow Koni

I have the Tein RA, and at least in Seattle-Oregon-Vancouver BC roads, this suspension is as best describe as streetable Track stuff... Now if you do value ride comfort in everyday driving, Koni Yellow would be much better choice.
I'm not saying comptech is not better, if all the experienced track lappers/racers like Kip, Andrie recoment, I bet it's true!!! But like pbassjo had said, if the comptech is not as least 75% better, it won't justify the double the price of the other options... maybe the reason could apply that why I'm not driving a 02 nsx but a 91... Oh opps, I forgot I couldn't afford a new one anyway... :biggrin:
Now back to the original question:
Comparing Tein RA with Koni w/ race spring: It's a little vague when you stated race spings, Groud control, Dali, H&R, Eibach etc. all made different spring rate springs, but I believed they are generally a bit softer than the one on standard Tein RA coilover: 10k front, 12k rear.
Unsprung weight: TeinRA all aluminum construction would save you some weight than the Koni yellow.
The ease of adjustability, Tein suspension adjustment is in "clicks", so it's easier to record and adjust if needed, versus Koni's adjustment is infinate, so you kind of have to record how many turns...or how many degrees you have turn...you got the idea. Now everyone had pointed out the koni are a little more on soft side, that gives you more controlability and also the comfort on the street.
Now I'm puzzled with the TeinRA shocks are too harsh comment by Andrie... Again, as far as experience goes, he's probably 1000 times better than me. (I took whatever he said as golden rule.) However, with my non stock alignment (previous owner and the suspension intaller tuned it to be neutral handling and maximize tire life, my car is not too low either.) I found when I was on my local track, Pacific raceway, the stiffer I set up, the better I felt. Even my track is sort of bumpy. Also my car does not experience any excessive oversteering with the 10k,12k springs... Note: my car only had the RA as suspension mod. and use stock 15/16 setup on track. So if the car had different suspension mods or using differet tire/wheel setup, then the RA could be too stiff even on track.
Price: TeinRA maybe a little bit more in retail price, but if you comparing the re-sell value should you upgrade to something else (diff. car or diff. suspension) They might cost you the same...
Last note: Even you have someone nice enough to let you drive or sit in their suspension, your impression could still be different when you own the car. (kind of like the first month dating vs. 3 years after marriage
LOL.) My suggestion on evaluating the harshness for street use, if you had even the slighest discomfort with the suspension setup, it will not be the suspension for you.
Hope it helps you making decision.
