I just bought a set of F-Sport springs, going to have a local shop put them on next week. Planning to buy a couple Tein Rubber Silencers to avoid the infamous "clunk". I'm assuming the front don't need them.

1. How many sets should I buy? Some people recommend 5 packs (completely cover all 4 dead coils) and some say only 3 packs?

2. What part of the coils do I install them on? Are there any pictures or guides?

ill see if i can get some pictures for you. i bought 5 packs (thats 10 total silencers). #1 and # 2 silencers were installed end to end starting from the top. #3 spacer i put about 3 inches from the end of #2. #4 and #5 i put about a half coil space in between starting from #3. you don't want to completely cover the first 4 or 5 coils, you want to allow some space between the silencers. i have the eibach springs and after i put on 5 silencers on each side, it raised my car up about 1/8" ill see if i can take some pictures tomorrow and post them up.

I actually just had the F-Sport springs w/ Silencers installed less than a month ago. I went with 5 packs, as suggested on this forum. It probably is overkill since Tein Springs have I believe 2 or 3 silencers on each coil from the factory, but I have NO CLUNK whatsoever. I just installed them on the rear coils leaving room for installation on the top. I spaced them about a half inch b/t each silencer for room for movement. It may be overkill, but 5 on each rear coil did it for me.

You guys are probably right, 5 each side seems like overkill. Putting them too close together seems like it'll raise the car a bit also.

I'm thinking just 3 per side with the length of the silencer between each silencer. #1 silencer at near the top, #2 will be the silencer length apart from #1, same for #3. How does that sound?

i only put 1 pair on each i think one at the dead coils at the bottom and 1 sumwhere in the middle..

is it possible to install the silencers w/o taking off the springs from the strut?
i don't want to go bak to the shop again

what size??? 60-90mm? 90-130mm? 130mm+?

It's the 90-130. Unfortunately, they are backordered for 6 weeks at options auto salon. I just ordered some.

i have 3 sets for sale if anyone needs them

yes you can install them without taking the spring off. the silencers have a cut on them that will alow you to just slip them on.

thanks! i m gona try putton them on, mine's been clunking like crazy

I put them on my prokit springs, took one side off for a test and no clunk. So it turns out I didnt need them anyway. Its odd that some people dont have the clunk and some do.

mine clunked almost over every bump at medium speed
didn't use the tein silencers tho since nobody local carried them
but a pvc hose worked like a charm for me

i have f-sport..they clunk on big dips, not annoyingly every single bump..silencers would be a good idea but i don't mind it hear n there..
