Performance Caliper Guide Bushing

Hello Everyone,

What are your thoughts about this?

"Reduced caliper deflection, enhanced pedal feel, and improved pad wear. An excellent way to improve braking performance".

Thank you.

I like them. Been running bimmerworlds version on my front calipers for several years and ran them front and rear on my E36M3 for about ten years. You must grease them periodically but once a year is probably enough unless you really use the brakes a lot or track the car—I don’t track and drive about 8k miles a year mostly highway.

Add braided lines, good fluid, titanium shims if you track the car, and higher temp pads if you track the car. For ridiculous cold bite but lots of dust and maybe some squealing run Hawk HP Plus. I use Stoptech Street and they have a little less cold bite than stock but more fade resistance (which I don’t need for my street driving).

I ran them for years on my E46M for track use. Worked extremely well.

I've got new rotors and PFC Z Rated pads to be installed soon and thought about using these bushings. It seems like it is a good idea.

Thank you guys.

I noticed that the spiro lock grooves on the short bushings don't seat flush to the calipers, having therefore an axial play. Have you guys encountered this as well? Just the short ones. Long ones are kind of ok.

Long

Short

Thank you.

I noticed the same on the bushings I installed on the rear calipers but I think that's just a last resort safety issue anyway to make sure it doesn't come out (into the rotor side) for some reason. The interference fit for my bushings was really tight and it's hard to imagine them coming loose unless you get the caliper really, really hot.

I would not worry if the bushings were pretty tight in the bore (press fitted), but they got in kind of loose, so they are moving. I am not very comfortable with the play, but it may not be an issue. I have contacted ECS but it looks like they don't really care. Might just return the parts.

Thanks.

VictorH · 01-16-2018, 06:34 PM

That's really weird. I don't think they should be loose at all. The way the bushings come out of the package with the knurling (and given how tight they were for me) makes me think they are designed to be a tight interference fit.

I wouldn't feel comfortable with that weeny spiral lock to keep the bushing in place if the bushing fit is loose. That just seems like a bad idea. Sorry you've had a bad experience.

I agree. BTW, did the spiro lock grooves seat flush on the calipers on your install?

VictorH · 01-17-2018, 06:20 AM

No, they were about an 1/8" to 1/16" away from the caliper, just like yours.
So, I guess in your case they are going to wobble back and forth in the caliper. I wouldn't go for that.

pbonsalb · 01-17-2018, 07:26 AM

The ECS ones look like the only press fit ones since they have the knurled end. The others don’t fit as tight and the instructions say not to press the in but rather to sand the hole until the guide fits the caliper. The pin should be a fairly tight fit to the guide but you still need room for a little grease in there and they have to be able to slide freely with the caliper bracket.

The installation instructions calls for a press fit install, so much so that ECS sells a "tool" to help doing the job (totally worthless BTW). Instructions show a C clamp is needed. Not in my case.
Contacting ECS is pretty impossible other than an online chat, so I guess I am stuck with a product I don't want anymore and have no support for.

Thanks again.

Pins fit properly, no issues there. But bushings are not press fit and do have an axial play (with minimum radial, relying on the spiro locks only. Not sure is this is an OK solution.
I do understand that as long as the pins move freely without much friction (properly lubricated), that wont be enough friction forcing the bushings out, but by default, bushings should be press fit and spiro lock in place as a safety precaution.

pbonsalb · 01-17-2018, 09:17 AM

Maybe it is ok since the other versions like Bimmerworld can move back and forth in the caliper up to the C-ring and flange limits.

Sammy82 · 01-17-2018, 09:20 AM

I run the bushing kit, front and rear, from Bimmerworld in my E92 M3.
I`m very satisfied with this upgrade

Buy them, can`t go wrong with this

You may be right. If I could only have an answer from ECS... However, if I understand you correctly, the flange will only prevent the bushing to move outwards, which is not a big deal. Inwards at the same time would be bad. But then, maybe the spiro lock can hold it in place if needed.
Thanks!

I would if I could return the ECS. But it doesn't look like I have this option.

Sammy82 · 01-17-2018, 09:30 AM

Why can´t you return them to ECS?

I could only contact them thru an online chat. I was asked to email them pictures of what is going on, which I did, and they would get back to me. I am still waiting to hear from them (3 days now) and cant get a person on the phone.

Sammy82 · 01-17-2018, 09:45 AM

Hm, that's not a good customer service if requests are so long in coming

Correct. I have sent the email three times so far... Needless to say that I will not buy from them again.

jeffkukuruda · 01-18-2018, 10:30 PM

i've returned a handful of things to ECS, while their customer service isn't American Express level, I've found it decent if you pick up the phone. For all my returns, I've called them and gotten an RMA number and sent them back, no issues after that.

good luck,
Jeff

PS... I have these bushings on my e39 M5 from a year or two ago and they fit VERY tight, broke one cheap c clamp installing.
