Wow I run a lot more droop! For a 5.5mm ride height, I have droop set as 0 front and -4 rear
Mind you am struggling with on power over steer in VTA, would a Sway bar help (I have a pair but only one set of bulkhead mounts so I can only put one on, is it worthwhile, if so which one and where?)
Any other ideas to plant the rear end a tad? Got soft springs at rear 2nd hole from centre, Medium-Hard springs up front 2nd hole out, 2mm shims on roll centre on bulkhead, no shims on outside hubs, -1 camber front, -1.5 camber rear, 2 degrees toe out front 2 degrees toe in rear with narrow suspension blocks.

2 degrees toe out up front is too much. I run 0 to 0.5 degrees out on each tire. Reduce your front toe and it will help the rear end and reduce lap times. You could also try 1 degree rear toe.
Have you weight balanced the car? Front to rear and left to right. This will help a ton with consistent handling.

What is your rear diff fluid? I'm currently running 80wt shock oil and love it. A lighter oil will allow the diff to free up and roll through the turns better.

Dang! I broke a rear bulkhead cover while making a couple practice laps before our club race today. It was a good thing I brought an extra car for a class I haven't been racing lately. I ordered the aluminum front and rear covers, plus the spacers from HotShotRC.

Sorry i'm late to this conversation, but here's my settings for VTA on medium grip asphalt.
Box stock with the following exceptions:
Front Springs - 35wt oil, Associated Silver spring (14.5lb)
Rear Springs- 35 wt oil, Associated Gold spring (19.5lb)- 2mm preload spacer
Front Track- I added a 1mm spacer between the hex adapter and the wheel to widen the front track
Rear Inner Camber link- 2mm Spacer
Rear Toe Block- 3*
Car runs like a dream.

By adding the spacer on the wheel you are reducing the hex contact area on the wheel increasing the chance of damage. I would recommend getting wider hexes instead of spacers .3racing has them from 4mm to 7mm. I do agree that widening the front track can help the car.

The Sakura Zero S is my first TC and its been a great experience so far.
I need some advice on how to get more steering.
I built it following the manual exactly. Besides the 19t pulley my car is stock. At the track (medium grip asphalt) I felt the car was slower down the straights and the rear would sometimes spin out coming out of a turn.
A pro offered to setup my car and he immediately noticed that the stock setup had massive toe-out in the front. He set it to 1*. Height was set to 5mm front and back. As soon as I got back on the track I noticed I could go faster down the straights and the rear was more planted. But now I do not have enough on power steering and I have to slow down to make the turn.
It looks like that massive toe out in the front was giving me plenty of steering at the expense of speed. I was recommended to switch the front to a lighter oil possibly 35wt and/or softer spring. Does anyone what wt is the stock oil? It looks like the stock spring is 5.5t, and the softest Sakura spring would be 6.5t. Not sure if that would make enough of a difference.

I'll definitely consider the rear toe changes. Especially since I believe that i have this car the way i want it. I'll report back when i can.
As for the front spacers, it's what i had in my box at the track that day. I'm pretty sure they are actually the #8 washers that originally came with the RC10 to raise the height of the body mounts. I'll look into different spacers, but the outside diameter of the spacer is 11mm and fits into the hex on the wheel nicely.

You may want to try less rear toe for vta. I'm running 1 or 0 depending on the night. I bet your losing a tenth by running 3. That's a lot of rear toe and a lot of tire scrub.

Also try 2 degrees of camber on all tires. This may help as well.
Since you are having an on power issue it means that to much weight is shifting toward the rear of the car. Stiffening the rear will have more effect then softening the front. You may need to soften all four corners to prevent the rear from being too stiff as I have recommended above to get the balance correct.

Hi GDF, with my sakura zero, I run 6.5 rear and 5.75 front springs with 35 oil in front and rear dampers. camber = 2* all round.
ride height is 5mm front and rear. 5mm hexes front and 4mm rear.
toe = 1* out on the front, and for 13.5 i have 3*in on rear - and 0 toe for stock.
hope this helps some
