also to add to Arith's post,
if you tyres are 1 directional its better rotating the tyres using a tyre guy where they they off the tyre of the rim and put on opposite corner or other side. You'll get better wear rather than just changing front to back, back to front.
highly recommend the Yokohama S Drive, unbelievable in the rain, I feel invincible sometimes. I was first told about them when my friend sat in someones EVO 9 flying around corners at 160KM/h in the rain.
Then I heard during the Yokohama track day it started raining and guys with the S Drives were easily outforming the Bridgestone S03 (higher performance tyre than RE050A) cars they also brought along.
Also recommend the Bridgeston Adrenalin. I'm subscribed to a 100+ thread post on Ozhonda, and ppl rave about it.
