Anyone do anything to lessen the road noise inside the cabin of a 4G TL tech. I intend to put b-quiet v comp on the front doors but thought i'd ask here first.

change your tires, I changed to continental DWS and it is quieter. No doubt dampening will help but changing tires is easier.

 

Hi OP,
I dont think insulating doors will make too much of a difference. To effectively reduce the road noise, the best thing to do will be to put insulation inside the doors and under the carpet. Just my .

Personally, I wont do it. I think the car is quiet enough as it is for my taste, but everyone is different.

 

Dynamat the whole car.

 

I find that road noise depends on what type of road I drive on. The quietest is newly paved asphault. Cement paved or roads that need to be repaved with lots of truck traffic make for a lot of road noise.

 

^this, the majority of road noise comes from shitty tires, or crazy tread. the rest of the time it is a wheel hub, improperly balanced tires or shitty alignment

 

+1 Road noise is generally tires. Am running oversized Conti DW Summers on my 3er with a big reduction in both noise & bump harshness over the factory Bridgstone Potenza that the car came with.

 

i know its the tires. But my tires still have a lot of life in them. Putting some vcomp stuff will cost me $200 max, i think. just getting some input. i'll look into replacing the tires to a different type when they are due.

 

Yeah, I would put some sound dampening material in. I'd put it in the floor on the trunk and underneath the rear seats. The doors would help too of course.

I plan to do this some day as well.

 

I think this is the best plan.

I'm going to do 2 boxes of vcomp for trunk & floorboards and then 1 box of extreme for the 4 doors. That's my plan but I doubt I will have time to get to it until this winter.

 

well, just for all to know. i took the doors apart and put v-comp on the door panel and dynamat extreme on the metal portion of the doors. to see if it made a difference, i first put the combination on the driver side door. drove around and could hear significant road noise coming from the passenger side. drivers side was much quieter. i now have the combination on three doors and will need to put on the rear right door. as a whole, it quieted the cabin quite a bit but not totally eliminating noise. another thing i noticed was the bass response from the stock speakers is much better i guess due to the better seal of the dynamat compared to the original plastic. doors also close more solidly with a solid thud. took me about 3 hrs per door just because i had to wait for the glue applied to the v-comp to dry. v-comp does not come with adhesive. i'm not sure if the adhesive i used will hold up - i used 3m 80 spray adhesive and put some aluminum tape as added support. I will check in a couple of weeks.

for those with 2010 tl tech, there are four screws to remove before taking the door apart. i can provide info if needed. took me a while to find the fourth screw. i kinda messed up my drivers door a little bit - i just try not to look at the minimal damage i created. not too obvious - except for me.

i bought two boxes of v-comp. one box is sufficient to do four doors. i intend to use the second box for the front firewall and floors to see if it eliminates even more noise.

 

Is it really that bad?

 

tires....the oem michelins are horrible....i have had them on my last 3 cars, and cant get them off soon enough...if the next car i get has these tires on them, i am going to negotiate a different set of tire....
