Here is the latest update of the iRacing Trucks Setup Sheet.

I just added the weight ballast settings to it.

Let me know if you want anything else added to the sheet.

This post will grow as I find more useful bits of information.

Here is a good link on corner weights Grass Roots Racing

One of the most asked questions when it comes to oval cars is what is wedge and how do i use it?

What exactly does wedge do?

Wedge (RR Spring Perch Offset) works to loosen or tighten the vehicle.

Go up > if you want to be tighter (mainly on entry and through the middle)

Go down < if you want to be looser (mainly on entry and though the middle)

Going up on the RR Perch lowers the ride heights of all 4 corners but its more dramatic on the RR.

Going down on the RR Perch does the exact opposite of directly above.

The quick and dirty way to remember this in the car is the same as bolts.

“Lefty loosey, Righty Tighty”  ie using the left arrow to decrease the number makes the car looser, right arrow to increase the number and tighten it up.

Continued details from part 1 of Aaron’s quickfix guide which you can see HERE

Erratic Braking:

soften front springs/shocks

even out front springs/shocks

Ride Height details:

Too low a ride height could cause the car to bottom out..

The higher the RF ride height the tighter the car will be.

The higher the REAR ride heights, the more drag on the straight-aways, but the better the rear will stick in the corners.

A higher LF will tighten the chassis.

A higher LR will loosen the chassis.

A higher RR will tighten the chassis.

A higher LR lowers the RF and may cause the RF of the chassis to drag.

General Oversteer

more front sway bar

less rear sway bar

decrease wheel lock

lower rear shocks

raise front tire pressure

more cross weight

move rear weight forward

Lower rear tire pressure

General Understeer

less front sway bar

more rear sway bar

increase wheel lock

raise rear shocks

lower front tire pressure

less cross weight

move rear weight back

raise rear tire pressure

SHOCK COMPRESSION:
The stiffer the FRONT shocks, (higher the number) the tighter the car will be when braking.
The softer the FRONT shocks, (lower the number) the looser the car will be when braking.

The stiffer the REAR shocks, (higher the number) the looser the car will be under acceleration.
The softer the REAR shocks, (lower the number) the tighter the car will be under acceleration.

SHOCK REBOUND:
The stiffer the FRONT shocks, (higher the number) the tighter the car will be under acceleration.
The softer the FRONT shocks, (lower the number) the looser the car will be under acceleration.

The stiffer the REAR shocks, (higher the number) the looser the car will be under braking.
The softer the REAR shocks, (lower the number) the tighter the car will be under braking.

Shock details:
RF

• Higher compression will tighten the chassis entering a corner.
• Lower compression will loosen the chassis entering a corner.
• Higher rebound will tighten the chassis accelerating out of a corner.
• Lower rebound will loosen the chassis accelerating out of a corner.
• Overall stiffer RF shock will tighten chassis, weaker will loosen it.

RR

• Higher compression will loosen the chassis accelerating out of a corner.
• Lower compression will tighten the chassis accelerating out of a corner.
• Higher rebound will loosen the chassis entering a corner.
• Lower rebound will tighten the chassis entering a corner.
• Overall stiffer RR shock will loosen chassis, weaker will tighten it.

LF

• Higher compression will tighten the chassis entering a corner.
• Lower compression will loosen the chassis entering a corner.
• Higher rebound will tighten the chassis accelerating out of a corner.
• Lower rebound will loosen the chassis accelerating out of a corner.
• Overall stiffer LF shock will loosen chassis, weaker will tighten it.

LR

• Higher compression will loosen the chassis accelerating out of a corner.
• Lower compression will tighten the chassis accelerating out of a corner.
• Higher rebound will loosen the chassis entering a corner.
• Lower rebound will tighten the chassis entering a corner.
• Overall stiffer LR shock will tighten chassis, weaker will loosen it.
