I hear for it to fit on Xi we just need the "I" top hats. Can you confirm? If so you should sell as a package for Xi applications

This is correct as I have done the I tophats on my 09 Lci xdrive and it works perfect. IT HAS BEEN CONFIRMED

neilvosko · 07-29-2012, 07:21 PM

wow, i am still having issues. poping and clunking and then car pulls to the side i turned AFTER i straighten the wheel. everything looks tight and intact. WTF? please help.

I had mine installed by a professional and we re-used the rubber part as he was worried about noise etc. Regardless the car is lower and I love it.

I don't get the washer notes. Is it any different from stock? Does it have to be flipped?

Yes send me pics to eric@supremepower.com

Im wondering now if the bottom of the shock is all the way into the spindle. I have seen a customer who came in with the shock not all the way into the spindle and it caused the car to do some crazy things.

Yes this is now confirmed. XI models can order the lowering hats and the upper hats from us.

The rubber is not needed. Only effect is it would not lower it all the way.

#8 in the photo below needs the flat part of the washer to be lower than the domed portion which the bearing from the top hat sits on.

uhhh... compresssed springs and OEM ride quality? impossible.

ED: i should also note, compressing springs, much like adding lowered springs, will reduce the life of the strut, not only compromise ride quality and safety... do this at your own risk .

These perches actually lengthen the static distance from Bottom Spring Perch (fixed on strut) to Top Spring Perch (Supreme Power) so the spring is not as compressed upon top hat assembly as it was with stock top hat.

Thus, the car now sees an initially lighter spring (same spring but not as compressed as stock assembly) with the strut sitting further into its stroke (hence the approximate 0.5 inch lowering), and in my case has further increases bump stop activity. Outcome will vary based on existing strut/spring that is used and their related baseline performance.

You have provided a lot of good feedback and I plan on buying from you.

I disagree with your statement that the rubber is not needed. The thickness of the rubber will have minimum effect on the ride height, but it provides movement without squeaks and pops. I'm not a mechanic, but as an engineer I understand the function.

Every car I have worked on has rubber between the spring and the perch. Car makers do not add unnecessary parts on their cars unless it is needed.

supremepower · 11-21-2012, 01:12 PM

The rubber is not needed. The perches have a spring built into them and once there is load on the perch from the weight of the car being applied on the entire suspension there is no movement.

This never was about the thickness of the rubber having an effect on ride height. It was more how the rubber fit on the new perch and the fact that its not needed.

If properly installed there are no squeeks or pops at all.

If you would like to install the rubber perch you can. We just dont recommend it.

Nice review! Very interested.

if 'the strut is sitting further into its stroke', does that mean I'll wear out my struts faster with the perches then without?
