im actually in the process of looking rite now. i was going to sugest that to you. if i remember correctly the gt-01 set has all four shocks the same. and the gb-01 has smaller fronts.

here is the pic of all the shocks i got. the aluminum ones are the 3racing gt-01 the cva is tamiya gb-01 and the yellows is the original rtr ones. the longer cva's are for the rear, and the shorter are for the front. the 3 racing seem to be the same size as the front ones.
