Noisy H&R lowering springs Options

[wazzuu]

I have just bought and installed progressive H&R lowering springs 29964-1 for Toyota Celica T20 (3S-GE 2.0L engine, 129KW, chassis code ST202). Immediately after install, i noticed clunking noise over even slightly rough terrain. Also noticed that two lower coils are binding together when the car is stationary with no extra load.



Is this normal? Are those dead coils supposed to be there? Should i buy some sort of spring silencers?

My setup includes brand new KYB Excel-G shock absorbers.

Thank for replies. Here's what H&R rep have to say:

Is this normal? No, clunking of any other noise is not normal.

Are those dead coils supposed to be there? Yes dead coils are designed to be touching one another.

If the springs have a different diameter top and bottom it is self-evident as far as which way they should be installed. Whenever possible we try and design the springs so that the inactive or dead coils are at the top.

Should i buy some sort of spring silencers? No, anything added to silence a noise is more of a bandaid. Please have all your bushings inspected, this is a good starting point especially on older model vehicles.

Think that those answers can be of some benefit to the members.

I went to the mechanics today and they said i must shorten the front shocks for a centimeter or two and that they will measure everything and come out with advice. This is pretty familiar to me, as i know a couple of people who did that and everything went back to normal.
