Hi, installed H&R Lowering spring with 17mm pads, and not happy with rear, compare to the front, it's too high. I have 2012 coupe with pp, and why looks so weird. my car comes with 17mm pad, someone can tell me the parts no. of 13mm pads?

Roswell

I doubt ur car came with 17mm pads oem. As far as I know, we all have 13mm pads unless u bought the car used & the previous owner did some suspension work.

With that being said, I think both parts # are in the sticky or search for superbubblicity thread.

scc2687

thank you, i think previous owner may change it to 17mm, i was thinking another 5mm drop won't help, i will stay with 17mm.

Roswell

Yeah, I'm using the thicker pads & love the look. It also saved me from rubbing after going wider tires &/or adding spacers to my oem wheels.

I WILL UPDATE PIC TONIGHT, THX

pics updated. rear looks too high. any ideas?

Roswell

Something is definitely not installed correctly or u have more than 17mm spring pads in the rear. Mine sits even front & rear.

Did u buy Benson wheels? U must be from Toronto. Lol

scc2687

yes, i am in toronto, i have to talk to my mechanic, my mechanic told me the pads were 17mm(confirmed with the parts no.) is there any other reason ?

Roswell

Strange, looks like the pads are not sitting properly. Is it high on both sides?

scc2687

yes, both are the same height.

Roswell

Well ask ur installed to double check everything cuz it shouldn't sit that high. U can search for pics of members with 17mm pads, they are pretty even. 13mm the car sits a tad lower in the rear.

Another thing I can think of is u got the wrong H&R springs ? What is the part # for the springs? And if u know the previous owner, ask why the car came with 17mm pads?

scc2687

should be the right c63 spring, i checked the parts no. of the box. and i just checked the the height again. i have samll hands. front is half finger, rear left is more than a finger, rear right 2/3 finger. i parked my at my garage. thx

Roswell

My part # is 29028-1 , but I have a sedan.

scc2687

sedan and coupe use the spring, i have the same spring as yours. rear left is higher than rear right. i have to talk to my mechanic , thx

Roswell

It's normal that driver rear is higher than passenger rear, our cars are built that way. What is not normal is the rake look regardless of 13mm or 17mm pads used.

Keep us updated.

scc2687

thx

It almost looks like you have 2 spring pads in the rear. That's way high. Are the springs indexed correctly? By that i mean do the grooves on the control arms match how the springs are sitting in them?

scc2687

not sure, thank you, i use flashlight checked the pads, they looks like 17mm pads

Anyone have problems with knocking/clunking noise coming from the front?

Roswell

OP, here is the thread of H&R with or w/o thicker spring pads, lots of pics here to compare.

You might have a bad bushing? I would get it checked, I doubt it has anything to do with the H&R springs itself.

scc2687

i had this noise before, when brake or accelerate. not go over speed bump. mechanic checked that camber bolt was not tight enough.

w204nyc

I just had the springs installed two weeks ago. Nevet heard the noise before

I guess I'll go back and have them take a look. Its only at low speeds that you hear it
