Hey,

I just got my springs and now I am working on getting Sway bars. EVERYONE on this forum recomends UUC sways and I wil prorbably get those but according to this chart what makes them better....wouldn't thicker diameter in the bar make the car more stable and stiffer...UUC has the second smallest diameter in both front and rear...can someone help me out with this????
:dunno: :dunno: :bow:

SP Stock 24mm/20mm
Eibach 27mm/21mm
UUC 25.4mm/23.8mm
ACS 27mm/23mm
RD 27mm/24mm
Dinan 24mm/22 mm

Well, RD sways are highly regarded as well...

But, I alway recommend UUC for a number of reasons:

- great bang for the buck
- great company behind the product
- help support a forum sponsor

I think the UUC bars offer the best improvement in balance. E46s understeer enough already. The increase in diameter over stock is greater in back than in front to increase rear roll stifffness which increases front traction. Why increase understeer with an absurdly large front swaybar? YMMV

Service and support are top notch from UUC and that on top of an already outstanding product line makes it a top in my book. Being a forum sponsor helps as well. As far as you question about the different thickness of sways I dont know the answer.

Would the different/higher grade of steel make a difference since it would flex less overall?

The modulus of elasticity is essentially equal for all grades of steel so there is no difference in stiffness between chromoly bars and carbon steel bars. The chromoly steel used in the UUC bars has a higher ultimate strength, better corrosion resistance, and better fatigue strength than carbon steel.

Bigger/stiffer (less roll) isn't always the most desirable out come... especially on the street. While it might be great on a glass smooth race track, it could actually cause you to have less traction on a bumpy surface. Something to think about anyway.

Bigger isn't always better

The only criticism I have of the UUC anti-sway bars is how the rear bar comes into contact with the emergency brake cables

Really? Are there any adverse effects to having the sways touch the ebrake cables?

I have RD & love em. No problems, no noises, just flat cornering.

They only really hit when the e-brake is applied, but to me it's a flaw. I've been keeping an eye out for any wear and so far everything is OK.

Steve, I had this problem too and ended up cutting 0.5 inches off the ends of my rear bars.

half a inch heh? on both sides? what did you use to do it? and that solved the problem?

AND Rob L. is that something that maybe fixed in the future???

Thanks

I wrapped the contact area between the ebrake lines and the sways with vinyl tape....hopefully that gives it about 4 or 5 mm of rubbing room....:eeps:

 

[lilherc79]

Where is the chart that compares stiffness by %? that chart wuld help a lot here.

 

[KurriMasta]

although an incorrect and sloppy installation can cause many problems, it seems that many people are having clunking problems with their sways. in addition, if they sways interfere with the ebrake cable in any way, i would not even think about putting them on my car.

A buddy of mine has a machine shop so we used some special saw that made pretty short work of the sway bar ends. Then we use a bench grinder to smooth out the cut.

Any corrosion on the ends since you made the cuts?
