Default Sway bars differences in a stiffer front or a stiffer rear.

Why do some sell kits with a larger bar in the front and a smaller bar in the rear? I thought the best way to go would be a larger bar in the rear and smaller in the front???

I think the car comes stock with a bigger front than rear if that tells you anything.

Best is a relative term in suspension. Bigger rear can induce more oversteer or minimize understeer while a bigger front can do the opposite. However, swaybars are only one component of your suspension so what one person chooses to do with them should depend on the rest of their setup.

That was a good post. the reason why I am asking this is my set up is is a little different than most set ups. This is what I have

22mm bar in the front
24mm bar in the rear
tanabe front brace

Tanabe coilovers
448 front spring rates
336 rear spring rates
1.75 inch drop

front camber -1
rear camber -2
0 toe
stock caster

This set up set up works great and I redused my autocross time a ton with each change

2002-03 WRX come with 20mm front and 20mm rear bars on the sedan and 20mm front and 17mm rear on the wagon. although the new 04 WRX is different.

this is actually a pretty "standard" setup that many people are running when replacing both swaybars on the WRX. With the rear being a 22-24mm adjustable.

The stock setup as mentioned above of size matched or the rear being smaller is a lowest common denominator setup for safety with a tendency towards understeer at the limit.

you should dial in more front camber for autox... about -3 to -3.5 is great for turn-in

I need to get some front camber plates first. I have the front as negitive as it will go on the stock bolts.
