using now for just over 1k km mileage - dry grip is awesome, wet seems slightly better than 003, but no complaints from me so far

Good when its still have more than 60-70% thread , when you left like 10-15% thread need to be caution especially during the rain.

One thing that i like the most is , these tyre doesn't have those cracked line or tearing mark especially end of their lifetime. i have mine last for 50k km, thread left less than 10% but visually at the side wall still looks good.

What size are you looking at? Prices definitely vary depending on that.

With that being said, what i paid for RE003 is almost the same as RE004 (7 months already tho, changed at the beginning of the year).

I think its still running around Rm350 - 400 / pc nowadays. 

For 215/45/R17 that im currently running.
