The "best" depends on your bank account... the best affordable is a different question. Most people run tein, anywhere from basic street to custom. I know a fair few people like bilstein both fairly high quality coilovers
MCA up in QLD can now do you a bolt on set up with your choice of spring rate and valving for about $2k. I can't give you a drifting review but the car was super stable at motorkhana yesterday. Fair range in the damper adjustment too, should be pretty adaptable.
If you can afford the money for custom work Koni Shocks can be modified into coilovers, Koni actually sell the hardware to do so. A set of those with Eibach springs would be about the best setup money can buy...but its a LOT of money for shocks when you can get very good setups at a far more reasonable price.
