Just wondering if there is a preferred caliper bushings kit. I`ve been poking around, prices seem to run from 120-160 depending on the vendor. Any main differences/issues/etc.?

 

They're all pretty much the same... They work well, IMHO.

Just remember to pull the pins out and lube with anti-seize at least twice a year (or more, if you do more AX or track events or live in an area with salty air or roads)...

 

This one is common and seems to work OK for street, track or autocross using the stock brake calipers. I lube mine at least once per year. No problems. Works with all other brake upgrades.

HMS 3025 TyrolSport Brake Caliper Stiffening Kit $119.00
"TyrolSport’s revolutionary new Brake Caliper Stiffening bushings prevent the caliper flex inherent in the stock rubber-bushed design. This flex leads to uneven pad wear and rotor deposits under hard usage. An inexpensive upgrade to the stock that should be part of your next brake job. Track tested and mother approved! These are newly developed for the Mini Cooper and Mini Cooper S. They are offered for front calipers and back calipers and an availible stainless steel snapring option to replace the black phospate coated steel rings."

 

I prefer the best source for buying the kit. Some say it must be well tested before you buy it but i prefer reading the customers fedbacks when i buy a part.
