Smile MR-02mm Race Setup question

Hello All! Can You help me to make best setup for my car, please?
I want to get into mini-z's competition in my city.
Currently there are 3 classes in "racer":
1) stock (from the box);
2) hobby;
3) modified/unlimited.

I want to participate in hobby class. The main rules are:
- stock kyosho motor (without modifing);
- ni-mh, ni-ca accus;
- only kyosho mini-z bodies;
- diff 44t, pinion 6,7,8,9t;
- rewiring allowed;
- os-8 family fets, 1 per channel allowed;
- allowed aluminium parts that doesn't influence on car's performance (i.e. kyosho's aluminium motor pod), 0 degrees front parts (knuckles, toe etc.);
- allowed carbon H-plate;
- minimum weight - 185 gramms (with accus and everything else).

================================================

I decided to follow these main ideas:
- less weight;
- less wires and other power-eating things.

So... the body, that I've chosen, is silver McLaren HD kit due to its durability, stability and minimum weight. Chassis - MR-02mm.

Changed:
- removed rear wing, headlight's glasses;
- tires: 20 rear normal form), 30 front (normal form) + glued them on wheels;
- wheels - 0 offset rear/front;
- delrin kyosho diff;
- delrin pinion (9t installed);
- aluminium wheel nuts;
- longer antenna - 180mm;
- carbon H-plate (medium);
- bought new Kyosho's stock motor (it's better than motor from box) and removed resistor (it is allowed);
- changed fets to IRF7317, 1 per channel (4562 aren't available here, so the 7317's are the closest to them);
- rewired motor;
- removed dinky on/off switcher (less power loss);
- greased everything that should be greased =);
- polished diff shaft and kingpins;
- experimenting with accus: varta, sanyo and duramax (lenmar is also available, but haven't tested it yet).

The time is 2-3 secs better, than stock car. The only thing is car sometimes flips while turning 180 degrees corners... Maybe wider base? (+... offset rear/front wheels?)

What do You think else could be upgraded in this case?
Thanks in advance!!

Harder front springs may reduce your body roll on a hard corner and prevent the flips.

So you're not allowed to run negative camber? Shame, normally camber helps a lot with flips...

Can you lower your body/chassis without rubbing or bottoming out? Lower CG obviously helps with flipping, but only if it doesn't cause other weird issues.

No, AD band boards aren't allowed... Optional transmitter is allowed, but I think futaba 3pk is too much for a stock class. And only kyosho's stock springs.
Thinking of getting aluminium knuckles 0degs and +2 offset rear wheels (where is my dremel?), will experiment...
And another upgrade could be soldering antenna to wire and soldering motor wires to board + soldering power board wires to battery clips...
Uh uh uh

Thank You all for replies!

coming on the turn, slow down (let the the throttle finger off easily) take the turn smoothly (don't yank the steering). Most of the people would just work on their cars because the car is doing this and doing that. Think of the car as if you were inside the car and driving it...

In our track we have few 180 deg. turn. I have a McLaren and SC430 in mod class. Let me know if you want my set-up. I will help you to it.

good luck!
