That is one big track and would probably suit a really hard set up with a solid rear axle and front one-way.

Possibly brown springs on the front, light green on the rear. 80wgt oil in the front and 50 in the rear with anti-sway bars both at hardest setting and both big spacers in fron of the wishbone for caster angle.

For tyres I would say 45 shore front and 42 shore rear.

Start with 2deg camber on the front and 2.5deg camber on the rear with 0deg toe-in on front and 1.5deg toe-in on the rear.

I would never sell a car because I cant get it set up right. I would perservere until I do so. Changing the car wont cure the problem. All you will be doing is taking the problem with you. I know. I have done this many times. If I cant get a car to handle the way I want it too I now revert back to the factory settings and start again from scratch. I then just make single changes to see whether something works or whether it doesnt. But before I try another set up I always change the first one back to the factory setting. I always note down which changes helped and then once i have everything tried I start putting the different changes together in pairs and then in triples etc until I find the perfect balance.

Give this a try. You will be surprised.
That track don't exist anymore. It becomes a skate/rollerblade/bicycle park. Now, here in Austin, races are organize at parking lot. At times, you have real car in the middle of the track, where the owner left it. And we move from location to location after landlord chase us away.

For loose track and small here, i wouldn't recommend any lower then 42 shore rating for front and rear.

Try
Front:
60w oil
silver springs ( these are the ones that used to come with the GT4W)
2 hole pistons
1.5 or 2 degrees of camber
1 degree of toe out
Caster: 1 big clip toward the back and the other 2 toward the front
Use the inner holes of the high shock tower(not the low profile one)
Use the outer hole on the front arms
40s tires
Run either a oneway, or a diff with yokomo hard grease on it or 50.000 oil
5mm of ride height

Rear:
40w oil
Yellow or green springs( the yellow is softer, the green is the fluorecent one)
2 hole pistons
3 degrees of camber( the yok likes a lot of camber)
2 degrees of toe in
Use the inner holes on the shock tower
37s tires, preferably 30mm
Run the diff with yokomo grease ( theres a hard one and a regular one) or 30.000 oil
5.5 or 6mm of ride height

If he pushes use the rear sway bar, I have never used the fornt one, so I cant coment on that.

Let me know what the car is doing, pushing?, is it loose?

Thanks,

Steven Muller

I think he had a loose problem with the car, 50,000 in the front diff, 30,000 in the rear, and red yok springs up front and neo greens in the rear, what he had for toe and camber i'm not sure, but i'll give him your set up and go from there.


Thanks.

There is his problem right there. The Yokomo cars are critical to balance compared to most other cars. If the neon green is the Gt4 spring them the car wont handle because it hates having harder springs in the rear compared to the front. If this is the case I would suggest changing to silver in front and red in the rear

This will plant the car more in the rear without giving too much extra front push.

On the other hand if the neon green is the spring for the MR4-TC then it is the opposite and the rear is too soft compared to the front which also gives the feeling of the rear being loose. In this case I would suggest changing the rear springs to either dark green.

Default front diff?

Hi All,

I'm a newbie to nitro racing..doin some research on on-road cars and came across the gt-4 at LHS...everthing looked cool on it and much better than the HPI RTR car...

But the question I have is about the front differential? Does it not have one? and is that a good or bad thing? less traction or more?

I'm not really racing, just going to be running it at a local paved school lot...

thanks in advance

... on my setup list the most used one is the front solid rear diff combination, so good luck, the GT4-RTR its a good starting car ... and as is not much GT4-S's on the market, its very easy upgradeable to pure racing car.

hope this helps.

i believe it's 200 mm. when you go to the larger diameter rear tires, you'll want to switch to the 190 mm.

Umm.....let's see. Masami=Yokomo.

My guess is............GT-4?




Well, at least Masami is campaigning that car again.

..........Or maybe he's testing a prototype.
