I'd just like to say that I personally wouldn't bother with tyre recommendations unless they are coming from someone who owns the same car as you, and drives in a similar fashion.
For example, I had FK452's on the 360hp Cerb and they were very good, I have them on the 400hp Jag and they're abysmal. I wouldn't use anything else when I had the Cerb, I wouldn't buy them again for the Jag. The power delivery and vehicle charactersitics are entirely different between the two cars, and what works well for one, doesn't work at all for the other. Although they have similar power outputs, the peak torque is nearly 100lb/ft different, and the supercharged Jag produces considerably more torque at the lower rev range than the race oriented Cerb engine. The Jag is also a lot heavier, so the tyre has more work to do shoving the car forward (downforce from the extra weight of that Jag is probably not that much better, as the Cerb uses narrower tyres, 245 vs 275 so the Jag weight is spread over a wider surface area). Obviously there are differing recommended tyre pressures to take into account too. All this means that there are vast differences between the work these tyres are doing in these scenarios and, as such, even the same tyre types produce very different real life performance.
Basically, if you want to know what works, ask Mk1 MX-5 owners what they use, and bear in mind those who drive in a similar fashion to you (it's no use being told "these grip like glue" if the driver never pushes the car past 40mph, and only drives on hot sunny days).
