the uk cars (st205 ) were also a bit lower bhp than the jap imports were quoted at (239 vs 255) but jap cars were set for higher octane fuel so prob not much between the two as std.

mines the wrc version with the huge rear spoiler, and came with (non working!) anti lag, water injection and water spray for the chargecooler pre rad!

the st205 is deffo the one to go for, handle and brake very well, solidly built, and very tuneable. couple of them are now in the low 11s 1/4m times in the club.
the fensport cars (ie 600+bhp) are using the standard drivehafts, gearboxes and diffs.
