How much is the Dinan sway bar stiffer than the OEM?? I know its 27mm compared to 26mm for OEM but what % is it stiffer?

Im thinking of going with a stiffer front bar only and keeping the rear. I have a uuc front bar that i might be selling, its used. the rear bar is really no good as it isn't adjustable and ended up driving into my shaft.

Also, would u just recommend to stick with uuc front bar only and oem rear?? I need to decide what im gonna do either go with Dinan as it might match my stock suspension or just put the uuc front on my car.

i have 04 smg coupe, stock except for 245/275 tires. I want less body roll as the front of the car is sloppy to me.

Are you having understeer or oversteer? That will make a big difference. Usually M3s understeer so you want a little stiffer bar in the rear. BTW are you sure the rear bar isn't adjustable? I thought all UUC bars were adjustable.
