HELP ...My rear rce tarmac2 w/ raceseng 2" option top hats

Just installed the rce tarmac2 coilover With the 2" raceengs top hats and they're super noisy!! I got the set of tarmac2 from a local Buddy, he used them with oem top hats without any problem and now I got the raceseng top hats they're clunking on every road seams. I triple checked all the bolts and nuts, they are super tight already, Is this normal at all ?

I'm on wedsports 17x9 et35 w/ 255/40 hankook rs4 , -3.5 camber and 0 toe, I set the height about 25" from the ground to the fender all around and oem sway bar and links .

Went to a local shop and they said the rear struts were blown ....

Any input would be appreciated,
Thx guys

I'm running my tarmac2 w/ raceseng mounts front and rear and mine are silent. Sounds like something might be wrong.

Actually I have the same issue with my 2" top hats. I'm using them with KW coilovers.


I swapped them out back to the stock upper mounts and it's silent once again.


I don't think it's your spring choice, I think it's something to do with the top hats themselves. Maybe the upper and lower shock bushings that come with the top hats are loose, or the tolerance is off a bit... not sure.


I haven't yet approached @Raceseng about it yet as the car has been put away for the winter I'm busy at work so far and haven't even driven the car yet this year.

https://www.subarupartsamerica.com/p...iagram=7610485 Look at the diagram in the link. Did you put a new #4 they call it a spring seat seal, your OEM tophats should have it on there but it could be torn or broken.

That's what I'm suspecting too, the shock bushing that comes with the top hats seems a tad short or maybe has a little room to wiggle around, or the spherical bushing on top is something wrong....

I may try to use the oem top hats to find out if the top hats is the culprit this Sunday.

I'm not using the oem top hats currently, I'm using the raceseng rear top hats with the 2" extra bump room, but thinking to switch to the oem just out of my curiosity.

We generally don't recommend the 2" raceseng drop mounts for the rear with our RCE coilovers. 1 inch are okay.

I would reinstall with OEM rear top mounts and see if the noise goes away.

Aww man, wished if i knew this before getting them @Raceseng, But yeah I'll put the oem top hats back on tomorrow to sort out this issue.

And @Racecomp Engineering , what's the cost to rebuild the rears in the case if they're need to be rebuild ? And what to look for if a strut need to be rebuild beside if it is leaking oil ?

Thanks guys, I appreciate the inputs

Yeah but I don't think it'll fit in between the tarmac2 springs and the raceseng tophats tho....I'll double check the figment tomorrow.

I'm running the 1". How low did you drop the car? Maybe try raising it a bit to see if it gets rid of the noise.
