martin,
i tried to shim up the steering with the long posts, but the bulkhead was in the way. did you remove that part of the bulkhead to make the 2 tall posts fit? i used 3 mm tall shims on each side instead, and flipped the steering assembly over like you described. Also, is the Corrally motor good for non-boosted 17.5 stock racing? if it is, and if it is ROAR approved, it my be something i want to use at the REEDY Race this year.
thank you,
rich
