It depends on the length of the track you run on... For spurs and pinions, you have the following options that you can run on your 705;
1st gear spur
2nd gear spur
1st gear pinion
15T (909575 steel, 909555 aluminum)
16T (909576 steel, 909556 aluminum)
17T (909577 steel, 909557 aluminum)
2nd gear pinion
18T (909578 steel, 909558 aluminum)
19T (909579 steel, 909559 aluminum)
20T (909580 steel, 909560 aluminum)
Unlike other cars, you need not necessarily stick to a particular gear tooth jump for the Centax pinions and spurs. For example, you can use 50T/44T spurs (6 tooth jump) with 16T/18T pinions (2 tooth jump), so long as you tune your engine and 2nd speed gear engagement to suite.
To get a lower set of gearing for even smaller tracks, you can use the optional 22T brake pulley (909242), 17T rear side pulley (801252) and the 47T rear diff pulley (808376).
