Tein
lowering springs, suspension: Tein Spring Silencer Rubber - Spring No Noise Sleeve, COIL SPRING SILENCER PADS / SLEEVING

Wow, never knew such a thing existed. He is installing them now. Funny I have had aftermarket springs on all my vehicles and never had such a noise. Thanks for the info!

Considering these for my Z, no review posts since 2016?! :happydance:

1) the product hasn't changed, just read the existing reviews

2) they're springs. Not a ground breaking part

3) It's 2018. Get coilovers.

You can check our website out! This product alone has over 30 reviews :)

These are pretty much the "go-to" springs for the 370Z. Dont forget that you will need minimum rear Camber Bolts to get your camber close to within OEM Spec. Let me know if you have any questions.

Done! Looks and handles great!

Now need to decide on spacers size.
