I have also 95% finished G4S build and car is looking good; post pics in couple of days with motor installed and hopefully new body. Thanks Patto for helping out with dud part sent with kit.

my g4 width setup was front 197mm, rear 199mm

so i will test front 198mm, rear 200mm to solve rear slip probelm in next week.
were you running a smaller wheel base Gansei ? this can upset the rear grip in certain conditions. also tire split needs to be 2mm at all times to stop the car drivig out of corners from the rear. when your tires were at 60mm or below, what were the front tire sizes ? this may help with the problem.

muppet said that he used the UFO old black shoe(not UFO2 shoe) his first G4+ race

he did not like new shoe. because the new shoe was heavy

i started front 62.5mm, rear 65mm.

i did not check exactly front diameter.. But i remember front diameter was similar with rear diameter or a little bigger.

But i did not have rear slip problem in small rear tire diameter before G4+ conversion.

and car was more aggresive with Big tire diameter after G4+ conversion.


and i used front -2mm, rear -2mm wheelbase mod in G4S

i tested front 0mm, rear -2mm and -1mm wheelbase mod in G4+

But rear slip problem did not fixed in small rear diameter

ok, what about ride hieght ?
i notice a 5mm rear tire difference from good to bad rear grip. is this due to chassis hitting the ground and unloading the rear wheels ? or did you readjust the suspension for smaller tires ?

i did not check rear height.

But chassis did not hit the ground. if chassis hit, i could see spark.

i did not readjust suspension in small tires..


the setup changed after G4+ conversion is...

rear sus arm length was longer..

wheelbase difference.. (front short wheebase was removed)

and shock oil was 500wt. (i used 600wt in G4S)


i will try less front camber...

i used front camber 3.5. rear camber 4.0 in G4S to solve understeer.

But car was very aggresiive after conversion G4+

so i will reduce front camber .. and increase front shock oil about 600

Check your downstops, they could be screwed out too far and not allowing the arm to drop.
my droop was set at 1mm front, 6mm rear, i try to lengthen the shock bottom cup to total length of 67m, but i still can't get 6mm ride height when tire is smaller.

Do you mean rear droop was +6mm? This is probably why you can't get the ride height you want. I run between +2 and +4 rear droop and have no problem with ride height on small or large tyres.

yup rear droop is +6mm. hmm, i wonder if the new G4+ shock can solve this problem. my frenz using kyosho shock with +6mm droop can set it w/o a problem oso.

You can not transfer settings from some other brand as the geometry is not the same. I know Serpent drivers that use +8mm. There is no way this is going to work on a G4.

Set your droop to +2mm and you will see you instantly have enough ride height. Even if the shock length was 100mm you will still have the same ride height the way you have the car setup. A down stop (droop setting) is exactly that - stopping the suspension arm dropping beyond a certain point. If you limit this too much (like with +6mm droop setting) you won't get the ride height you want.

To see the difference, put you car on the droop blocks without wheels or shocks and start unwinding the droop screws and you will see the arm start to drop. Set it at +2mm and reattach the wheels and shocks and you will have whatever ride height you want(within reason of course). If you don't have setup blocks do the same thing but sit the car flat on a board or bench, you will see the same results just not as easily measured.

To use a setup item correctly, you need to first understand what it does and how it works and how it will affect the car.

The lack of rear grip could be from setting the rear arms to the longer length.
Set threar arms to the stock (outer) hinge pin location. This may make the difference.
