Trying to figure out the best LCA for me.
Read that the "combination" bushing LCA's that have polyurethane and spherical bearing have little NVH(noise,vibration,harshness) increase.
Steedas combos say they are for high HP applications with little increase in NVH.

and polyurethane on both sides dont really comment on the NVH.

Anyone who has installed these, which ones have you installed and did you notice an increase in NVH?

I assume the combo LCA's are better in performance.

 

I have dual poly ends on mine and I could hear an increase in NVH. It wasn't bad. At cruising speeds on the highway I can hear a kind of "whirring" noise that comes from the rear of the car. It's subtle but it's there and you can hear it.

Poly/rod ended would be worse but is from what I've read going to be the best compromise on performance vs. noise. The dual rod ends would be the worst and I've heard they are quite noisy.

 

I have the combination from BMR poly on one side and spherical on the other. They dont bother me at all and the only really way to find the noise is to know what you are listening for and trying to hear it. My car is a daily driver and i love these. If you have anymore questions let me know

 

I have the J&M polyball LCAs and I noticed gear whine on decel after installing them. Other than that, no more NVH.

 

did you do the install yourself? what is your thoughts on the relocation brackets? do the LCA's remove the wheel hop?

 

Yes i did the install with a buddy of mine while the car was on jackstands. As far as relocation brackets go im pretty sure that they are for lowered or cars that will be seeing a lot of drag time. Every car is different but because of my rod end on the axel side there is a bit of movement that is allowed which completely removes all of my whell hop.

Once agian the BMR poly/rod end non-adjustable LCA's are top notch with only a bit of added NVH. If you have any more questions please feel free to ask.
