Got some topen Falkens, ZR rated. Im Very impressed with them, The Prelude so much more nimble now and sharp bends are a breeze at speed.

Just wanted to express how much of a difference its had, I havnt had this mich fun with cornering since I had track tires on it last.

 

Falken GRB FK 451
Using the experience gained from ongoing, world-wide racing sucess the Falken engineers in Japan were given the task to create a new high performance road tyre that would set new standards in tyre design and construction. The result is the new Falken GRB FK 451 high performance radial. New silica tread compound significantly improves grip in wet weather optimising wet performance and wear resistance. Duel tread compound for excellent handling and durability. Wide steel belts and jointless nylon cap ply and layer give stiffer tread for outstanding grip and high speed stability. High tension carcass and high turn-up give stiffer tyre construction for quick response and precise handling. Long and hard apex and steel reinforcement in bead area give stiffer sidewall for quick handling response.

I can also highly recomend Kumho Supra's, from Korea of all places but from a racing background - good grip and very good value!!
