ballast question. HelP!

[Tower Turn 13]

Need help please! I have to have a 15 kg ballast on my 430 scuderia to meet weight regulations in my racing league. It is an MR car, and I need to know where to place the thing. Also I have no idea how ballast works and I don't think GT5 description covers it at all. Such as, which direction (+ or -) is forward, which is back? I'm looking to reduce understeer and stabilize the car. Any suggestions?

Move the slider to the left to put the weight over the front.
That'll give you more front grip and therefore less understeer.

MR and I believe 50/50 weight, stick it 5 to 10 clicks up front, run some laps then 5 to 10 in the rear and run some more laps. Compare the times and how the car felt to you. Go with what felt better, if it's not the same as your faster laps bring it closer to the set up you were faster on a few clicks at a rime until it feels good to you and is fast.

A lot of the time putting it in the rear to help rear wheel grip on exit hurts more then it helps making the front too light on exit causing you to understeer instead of oversteer.

Thanks guys. I'd assumed - was to the front based on the car graphic, but the description PD gives in the yellow question mark box isn't really explanatory whatsoever...

Anyway I do think it feels better to the front. This car is quite unruly IMO, not an easy tune .

Thanks for the help.

Haha thanks gogatrs. I should've just asked you to begin with 👍

You got it backwards. More weight = less lateral grip. You'd put it on the front to reduce oversteer.

that post above me is not accurate at all. I agree with the post saying to run laps w/ weights at different locations to see what feels best. I really base ballast weights based on feel, not so much the lap times produced, because although one setup may net 0.3 seconds on a hot lap, it should all be about consistensy. Atleast for me.

Oops, posted under an old account. Anyhoo, if you're going to argue against the laws of physics you'll need to make a better case.

I agree. Most people think that putting weight over the axle gives more grip to that set of tires. Maybe in a pickup truck when trying to pull a trailer out of the mudd. But in a car at max corner speed, the more weight you add to an end of a car, the more lateral grip the tires are required to carry. Adding weight kinda does both things, adds verticle load and lateral load. The higher the corner speed, the more that lateral load takes over.

I agree, the weighted end breaks loose first.
