We run on a sealed asphalt parking lot surface, that is treated with grape soda. The season starts out low grip and increases to a high medium grip in the summer. We run no sway bars. make sure you run a softer shore front than rear. Zero front droop and three in the rear. Start your tires at 60mm in the front and 62-62.5 in the rear. Adjust suspension to handle the bumps; oil wt, ride ht, spring wt etc. This should get you started in the right direction.

What about ride hight and shock springs are they the same ?

One last thing i will be buying a new engine what do you suggest between RB and Nova Rossi ( money is not an issue )

Thanks for looking

Both motors are good, but the Rossi is the better choice hands down.

Speed6: shocks on RTR and G4S are identical.

Hey folks. I just finished building my g4s and took it out for some break in running today. I am using the stock set up till I can get to my track & then will work on getting the most out of it. However, right out of the box the rear end wants to outrun the front end when accelerating in a straight line. I have checked for binding & there is absolutely none any where in the drivetrain. The front hub is locked as a solid axle as this is how it came out of the box. You would think that in this configuration it would be extremely stable in a straight line. It is anything but that! Tires on both ends are currently 62mm. Any Ideas would be greatly appreciated. Thanks.

what you can do is swap your rear tyre over so put your left on right and vice versa.The cause of this is that there are a lot of corners at your local track eg.more left turns more wear on left rear tyre and more right turns more wear on right tyre.I think that this is correct if not my apologies and the guys here will correct me if i have made a mistake

Funny thing you mentioned as I have a Hobao GPX4 RTR and some other hobbyist has said simular where RTR handles better than Pro or Pro needing more setup. Maybe to do with thinner chassis compared to stiff Pro chassis.

Mr Dawg,

Since I'm not familiar with what you mean by 'clutch post' and you say you got the car from a newb, I would strongly recommend setting the clutch up as per the manual. Everything the manual says about the clutch is correct and will make the car work.

Since the car won't move at all, I'm guessing that what he left out wasn't supposed to be left out.

I'd check the one-way and make sure it's actually completely locked and not just sending power to one side. I had that happen, and it only seems like it affected braking performance (spin out). But, I can't think of anything else. I do remember some guys having trouble with the one-way bearings not being secured properly in the housing. If you can't trace the problem with the car on the bench .I'd fire it up and lift the rear end and make sure the front is pulling correctly and do the same for the rear.

Seems like it has to be either the front or rear diff though. I'm beat, hope the helps in some way...

Clutch post = clutch weights ??

If that so, You need to add the weight on the clutch. ( Some says using only 1 weight on the left side works better than using 2 weight altogether ----> no strange engine bogging after 15 minutes of racing ).

For me I follow the manual, using 2 weights / clutch shoe.

Hey man, thanks for the reply I'll check that one way more thoroughly tomorrow & see. Been racking my brain on this one. The only other thing I can possibly think of is that perhaps I swapped an 18T & 19T in it.(std tranny) That would certainly make it do strange things.
