I recently purchased the F-sport springs from Sewell. The installation instructions do not mention anything about a rubber wrap for the dead coils. Do I need to purchase an additional part (i.e. a wrapping for the coils)? I'm not sure of the correct terminology for these. If so, what is the Lexus part # for these?

Also, I have ready several threads that discuss cutting the rubber stop when installing lowering springs. The installation instructions do not mention these either. Is this something that needs to be purchased, or is it already installed and can be re-used? Thanks in advance.

 

I installed the springs myself and I didn't cut the bumpstops.

You can buy the optional Tein rubber silencers for a reduced "clunk" noise in the rear. Otherwise, you will have a slight clunk like many others here, including myself.

 

+1 clunk noise here but since you haven't put them on might as well buy it so you wont hear it.

 

When i had mine installed my mechanic placed a total of 5 packs of silencers (4 in the back and 1 infront) on the "dead coils".. So far no clunk noise esp heard on bump stops.. i got my spring silencers here based on what other CL members are using..
