Tein SS coilovers are a nice alternative. You will have a decent ride quality, and the handling is very good. The icing on the cake is that they are not all that expensive...

If you want to spend a bit more money, do not go with the Tein Flex coilovers, but rather, go with the JICs from Road Race Engineering. THAT will be your best bet for handling. It turned Roy Narvaez's car from a drag car to one that won the road-racing segment of the SCC USCC.
