I geared my Reedy Mach2 at 3.88 with 38' timing on a tighter 36' x 60' carpet track.
I geared that same motor at 2.8 with 40' timing on a flowing asphalt track with a +200' backstretch.
Understood. What Pinion did you use to achieve the 3.88 for the tighter track? Sorry - just new to this on road stuff and there is no easy FDR sheet in the manual anywhere.

Final Drive Ratio = Transmission Ratio (Drive Ratio)
Final Drive Ratio = Diff/Pulley (Spur/Pinion)
Final Drive Ratio = 40/20 (66/34)
Final Drive Ratio = 2.0 (1.94)
Final Drive Ratio = 3.88

Got some time in today to run my Sakura Advance. Highly impressive car. After a few hours on the track I was within times I needed to be able to compete in the highly competitive racers locally. Only complaint is that the car doesn't have pill inserts for (rear toe/roll center/hingepin width) like a few other manufacturers. Other than that, very easy to drive and only needs a few changes from kit.

Got it! Thank you! I thought I had to calculate based on the transmission drive ratio like in offroad... didn't realize it was just the spur/pinon calculation.

Calculate it same as offroad.

Internal ratio = diff pulley/spur shaft pulley (probably 2.0 on this car)
FDR = (Spur/Pinion) x internal ratio

If I wanted to convert arms and hubs to X-ray, would they fit on the new advance?

Gordon, much of the suspension parts are xray compatible. I'm not at CarCar anymore. But I believe there is another guy there now who runs Sakuras. If you bump into him, take a look at his car.

I believe his name is Zac. His car was pretty fast. I know that he broke on his 2nd time out with it, hence the question

LoL.

I think that's my old car.

Yes, the t3/t4 suspension parts should work. I actually run xray c-hubs, in fact.

Chuck, how do you adjust arm height? Shims? And is there lots of slop/play in the kit arms?

Compared to my Sakura Zero S, there is considerably less play in the Sakura Advance. This is likely a result of the Sakura Zero S using plastic toe blocks and plastic washers.

Compared to my Sakura Xi, the suspension of the Sakura Advance is a lot softer and squishier out of the box. Smoothness is the same and there is no play. But the stock springs on the advance appear to be very soft.

Mine is on the way. For a shorter carpet track do you think the stock setup is still workable or should I be investing in some new stiffer springs as well?

For Asphalt the car was really locked in. I recently put in 0 degree hubs to try and free it up. I will have more details to follow.

Did you guys build the car with the instruction manual setup of 2k in the diff's? Or should i go for a 5k setup? Running small indoor carpet track.
