Only bad thing I can say about the DRs is using them in the rain. It's always a little hairy. Maybe next time if you have more budget try the R888. At your power level it will grip just as good and be better in the rain plus handle corners better. They last a little longer too.
They look good. I have used et street drag radials for a while now. Both the original and et street 2 and here in the rainy Miami weather. Never had an issue. When they start to wear out on wet smooth roads it will slide around a bit but if you keep your foot of the gas you will survive. Its one of the negative things of because race car. Is not as bad as people make it out to be though.
