yeah, they are a direct fit. i have a set of cf towers but the durability of the stock towers far outweighs the weight loss. i'm going to start some lightening of the st this week starting with the chassis braces, front upper mount, center diff brace and shock towers. i won't loose a pound but now that i have a crazy fast motor she's ready to do some main domination.

the mega zx-21 motor is a beast, it was born to ride in the hyper. so much bottom i actually went up a tooth on the clutchbell 13/46 and still would want to wheelie in some spots. crazy fast motor even on a "heavy" truggy.
