I drift almost any RWD vehicle that's best suited for drifting (in my honest opinion and with the exception of slow ones), such as:
Jaguar XJ13 and Ford Mark IV: To me, they're easy to drift so long as you don't go too fast while approaching towards corner AND that the vehicles don't make sudden, jerky, turns that would result in spinning out.
Lancia Stratos: Fun car and drift-friendly.
Lexus LF-A, Ford GT and Chevrolet Corvette ZR1: Even though they're high-performance vehicles, they do well in drifting (although not easy to handle).
Acura NSX RM and Toyota Supra (JZA70): Like the Stratos, they're also drift-friendly.
And as well as other RWD vehicles, with Comport Hard tires, no upgrades. I tried drifting a Mugen Civic once (due to it being FWD), though I had no luck due to its handling being tedious while trying to e-brake, turn and feathering the acceleration at the same time, with no luck.
As odd as I found...my New drift car is the Camaro Iroc Z Concept...still some tweeking to do, but it's giving some people a good run.I'm not much of a drifter at all, but my new drifter is starting to change that.
Recently, I began drifting at least two vehicles, such as the Roadster and RX7, both which are TC. The Roadster fairly drifts well, though it's a bit than drift friendly, though my RX-7 TC drifts very well with careful acceleration and steering. I'm still uncertain if I would be able to drift a FF vehicle and even though its pretty hard to do so, at least its not that impossible to do so.
Any car with any amount of power will drift BETTER if you install less sticky tires on the front. 722 hp viper gts with RH on back and either SS or intermediate depending on how tight the track is. try it. it will have you powersliding out of corners like a pro. it gets rid of the embarrassing tank slapper.
