as you can see, vs kyosho, the capricorn is at least 36g lighter in overall drivetrain mass. one time back in the day i took everything that spun besides belts, clutch and bearings (cvds, hexes, shafts, diffs, gears, everything) and compared xray vs kyosho. the kyosho evo wc at the time with titanium pins, titanium screws on the gears, basically all i could do.. was about 230g. Xray with all of their available lightweight parts (in dec 2008) was around 190g.
So I played with the #'s again since the 41t thing bothered me some and it's still raining.
lets say you are running the rrr stock, 23/55 and 16/60 gears 23t front pulley and 60/58mm tires.
0.87% more front drive
In contrast, lets say you run the 24t front pulley
3.33% more rear drive, you need 60/60 tires to be equal.
Lets say you run the 41t diff, same setup
1.53% more front drive with the 41t diff
0.85% more drive if you run less split, 60mm rears and 58.4mm fronts.
So really, true your fronts slightly bigger than the usual 2mm split and you are perfect. on my track we get massive rear tire wear so I will still cut 2mm and the car will just get better, and then worse later that it usually would in a 10 minute qualifier if I can go as small as 60 in the rear, might have to start at 61 or 62.
