The Sileighty, AE86s, and Lister Storm are my FR drifters. The RX-7 LM (GT1-style) does a nice job, too. And my setup on the SR Widebody has me smiling...on the other hand, the '82 Starlet is fun to rag on.
Lancia Delta S4 and Evo VI Rally Car are my choice for the 4WD drift.
Mid-engined drifters: GT40 Race Car, GT90, NSX '97, and 600LM are so fun right up to the limit.
FF: Not easy; but I've gotten the Neon and Lancia Y to drift here and there.
But geting the old 2000GT to drift 'n' slide is my toy right now; I call it "Grandpa Trueno"!
