If the TS has no issues to swing 1200+ for a set of RE002s, by all means.
I have used a lot of tyres in the past 6 years on the same car. AD07, RE001, PP2, PS3, GY F1 are few of the better ones.. I used to eat a pair up every 3 months. I used to track quite often and still drive the car fairly hard.

My current tyre, el-cheapo Achilles ATRs... bought on a whim just to try. It has 90% of the grip at 50% of the price. The breakaway characteristics of the cheaper tyre is different but its more on how you have to change how you drive to suit the characteristics of the tyre. its just as quick around street corners...and I can hang the car out on the knife edge just as easily of not easier that I could on the RE001 and AD07 and far better in deep standing water than either of them. In fact, from personal experience the ATRs are better than the MY01, Parada Spec 2, Silverstone Evol8 and Kumho KU31.

For a road/performance tyre, I still prefer the PS3, having had gone through 2 sets. I feel the RE001 (not tried the RE002 yet) had a bit too much compromise. Especially on comfort. The PS3 is a more balanced tyre. Doesn't excel in any one category, but does very well in almost all you could throw at it. Will probably go back to the PS3s when I am done with the ATR.
At the end it depends on how the TS drives and what he is looking for.

I figured if I were to track the car, nothing short of track tyres would suffice. All the street tyres will melt....worst being the T1R....not that you'd enjoy the soft sidewalls either.
And a point to note.... while it is true that you car sits on only 4 patches of rubber, its only 1/2 the story. Your cars suspension setup and the driver is equally important. No point getting a high grip tyre with more than likely abrupt breakaway characteristics. You are just going to crash, at a higher speed. The best litmus test of a good road tyre is its breakaway characteristics. A grippy tyre with an on/off breakaway characteristic will only catch a driver by surprise especially if the suspension if not tuned to match the tyre (hard settings will make it worst)

Like I said, only the TS knows how he drives.

I also drive a 1.6 Satria. And i've out run and out cornered cars with twice the power and on much better tyres when I am using normal road tyres. Why? Because my car is tuned for a very progressive breakaway characteristic, which mean I'm able to exploit 100% of the cars' grip all the time...since I know i can always catch it if it misbehaves....and allows the rear end of the car to steer itself around corners...rare for a FWD car.

Look at this way. While the super grippy tire may have 10% more grip, you may only push it to 90% for fear or breaking loose, while I can exploit the full potential of my tyres' grip....and most will agree, I will be having a whole lot more fun doing it.
