Uniroyals are great - I had the original RainSport's on my XR3i back in the day and they were superb. The grip in the wet is phenomenal. The only problem with them is hey can wear quickly due to being a slightly softer compound (like Yoko's can also do - the A520's wore ridiculously quickly)

I've had a set of Hankook V12 Evo (K110) tyres on my Lexus for the past 5 years, and recently replaced them with a set of V12 Evo2's (K120). I'd have to look at the mileage now to see how many I put on the first set but they wore well and had good grip - the IS isn't the most powerful thing on the road, but you still had to give it some, with the TRC off, to get it unstuck. Good value for money, my only gripe to them was they weren't the quietest tyres. That being said, I couldn't say they were any louder than a Goodyear or Pirelli might have been on the same car.
