Perhaps you can list down your complete current setup including tire diameter and shores...

Here is my current setup :

Kawahara 35 degree tires 26mm Front / 30mm Rear (unshaved)
White 1.9 springs at Front with 60 weight oil - one hole piston
Blue 1.7 springs at Rear with 40 weight oil - two holes piston
10,000 weight diff oil - rear
Front one way
Ride height: maybe 5mm Front / 7mm Rear
Camber: negative 1.5 Front / Rear
Toe In : 0 Front / 1.5 Rear
Suspension holes : #3 Front and #4 Rear (count from bottom)

weird huh ??

What about your front and rear droop settings? If you have too much coupled with uncut out of the box 65 mm tires, then you'll have a very lazy car which performs very weird.

Front caster?

It looks like the weight tranfers to the rear much faster than to the front. What about your front and rear sway bar settings?

I can only suggest this... Try equal front and rear springs with equal shock oil weights.

If everything fails, work from the stock setup and change accordingly. Try to work on the basic stuff like shock angles, sway bar settings, toe-in / out and camber of the tires. Set the camber of the tires according to the wear pattern. The front tires should wear flat while the rear should cone slightly to the inner side (i.e. bigger outer diameter than inner diameter).

your front appears too stiff while the back may be too soft??

Tires- Front 42 S @ 62mm/ Rear 40 S @ 60mm
Shocks- Front 60W/ Rear 60W (both stock pistons)/2nd hole up on both
Springs- Blue F&R
Camber- Front -1.5/Rear -2.0
Toe- Front +0.5 (out)/ Rear -2.0
Caster- 2mm in front
Droop- 5mm rear/2mm front
Ride- Rear- 5.5mm/Rear 4.5mm
Sway- Front horizontal/Rear- stock with about 2mm of bar showing
Rear diff- 50K
Front one-way
B- Ackerman
B- roll center blocks
16/19 pulley setup

Check all shock lengths and ensure they are equal (fronts equal to each other and rears the same as each other). You may have 2mm or more difference in shock lengths that may cause tweak problems. When you lift the front end at the centerline of the chassis- do they tires come off the ground at the same time? Rear??

I recommend you purchase the XXX-Main tuning guide to reference setting up your car. Next to my temp gun, it's the best RC investment I made- maybe even better!!

When you get to the track, you should be close enough that you should only have to mess with tire shores/sway bars.

Look up some setups off the Mugen site.

Thank you everyone I'm gonna take your prescriptions, and don't do evil things like experiments

Here is my current setup:

35 shore kawahara tires 26mm Front / 30mm Rear (unshaved)
stock blue springs at Front with 40w - one hole piston
stock Blue springs at Rear with 30w - two holes piston
10,000 weight diff oil - rear
Front one way
Ride height: 5mm Front / 6mm Rear
Camber: negative 1.5 Front / 2.5 Rear
Toe in : 0 deg. Front / 3 deg. Rear
Suspension holes : #2 Front and #2 Rear (count from bottom)
Ackerman : A
Rear Suspension Mount : Low
Droop : 1mm Front / 2mm Rear
Stabiliser : all flat - Front / stock - Rear
Caster: all the way to front side

I'm gonna test it on sunday, hopefully it works okay.

Someone said to me too stiff springs at front make the car agressive when turning ( easy to turn ) but it also make the car understeer.

I take it that it's 1 mm chassis uptravel from ride height before the front tires (or 2 mm for the rear tires) start to lift off the ground?

How do you mean by this? All caster clips behind the front upper arm or in front of upper arm?
