BMR Tech Tip: Clock those bushings after lowering your S550!

[kz]

No, you don't have to clock spherical bearings. But I would like to get a clarification on this as well. At which locations does the PP1 package come with spherical bearings instead of bushings?

Not enough of them that you don't have tighten fasteners at ride height - one of the RLCA inboard mounts (don't remember which one but other one has a bushing that Steeda / BMR has replacemement bearing for), toe link on the inboard (subframe mount) and tension link in the front - totally off my memory so might have messed up locations - but - since it still have bushings left, they need to be tightened at right height.

do I need to clock the bushings if I have FP struts shocks and BMR handling springs (as it's not a big of drop)?

Yes.

I'm lowered, but have no issues with weird noises or mismatched ride height, but the next time I have the car on the oil change lift I'm going to do this. A 3/4" drop will not create a huge preload on the bushings, but hey, why not..... Best to have the bushings unloaded at rest. With suspension dropped or raised, the bushings are always under tension, and have a minimal spring effect.

I replaced the pressed in suspension bushings in my 911 with spherical bearings with spherical stainless and derilin bushings, but it is not a daily driver. 5 years and 20K miles and they are good.

FWIW, I also had an E36 M3, and that car did NOT have spherical bushings.

Bump Stops

Bump stop trim dimensions for lowered cars pictured below. FRPP Bump stops are identical (same durometer as well) to the factory ones other than cut down. Save money and either cut your originals or order factory replacements to cut.



Alignment

Factory Spec
Front - Camber: -1.03 Total Toe: 0.00
Rear - Camber: -1.50 Total Toe: 0.23

Ford Performance Spec
Front - Camber: -1.55 Total Toe: 0.00
Rear - Camber: -1.98 Total Toe: 0.23

Any chance you have the torque specs for the 15mm bolts on the transmission mount? I see you have the 18 but I have to take the whole mount off…
