hey guys i have a question what are the advantages of having a thicker sway bar in the back than in the front (i own a ef ) i heard form ben oggle that if you put a thicker sway bar up front it will make the car understeer more any info will be helpful

 

Thicker rear, promotes oversteer.
Thicker front, promotes understeer.

most people will tell you to run a larger rear bar, or to unhook your front sway completly.

 

damn cool coo lthanks for the info

 

no problem.

You already had the idea down. lol

 

you use swaybars to tune the suspension. they add to the spring rate in a lateral change of motion (turning, or one side going over a bump). thus the less body roll. a secondary affect to this is actually reducing the "independent"-ness of independent suspension because youre linking both sides. so you get a point where you LOSE overall grip. however, this isnt always a BAD thing.

understeer means the front has less grip than the rear. oversteer is the opposite. this is a DYNAMIC situation. a car can be both oversteer at turn in, neutral at apex, and understeer at exit, as just one example.

cars typically understeer all around tho. to help reduce this understeer, you oversize the rear swaybar. this reduces grip in the rear but gains you better rotation to attack the turn.

for an EF, you really just want to add stiffness in the rear. this is also why spring rates are typically higher in the rear on a COMPETITIVE RACING car. and again, you use the swaybar as another tuning option to get better rotation. it acts differently than springs so it will do different things than springs.
