The lower control arm compliance bushings on later model Honda and Acura cars are notorious for failing prematurely. This is especially the case for cars with V6 power-trains. The added weight and torque output of the engine wreaks havoc on these bushings, wearing them out in 60,000 miles or less. Very uncharacteristic for a product that is lauded for it's reliability.
Fastline Performance has teamed up with top-level design and production studio Pro-Car Innovations to release a permanent solution to the ever-problematic compliance bushing. Until now, all that could be done to remedy the issue was to replace with new OEM parts. Now, PCI's highly engineered spherical bearing mount has been adapted for use on the popular late-model Acura vehicles that Heeltoe specializes in.

Included with this kit are a pair of spherical bearing compliance bushings and trailing lower control arm bushings. The bearing housings are cnc machined from 6061 aluminum, and anodized. The spacers are cnc machined from 4130 steel, and zinc plated. PCI warranties the product for up to 2 years from manufacturer defects.

Overall benefits:
Reduced torque steer
Better power delivery to the ground
Improved high-speed stability
DURABILITY
Reduce wheel hop

Cool. I'm sure the bump steer/toe kick is going to be pretty terrible with those. I bet on a track the car feels really dialed in though.

 

That's why I haven't pulled the trigger on these. Is there a reason that nobody offers a polyurethane option? Seems like it would be a good compromise between all-metal and rubber. Is there a reason that polyurethane wouldn't work for this particular application?

 

Well vibrations are really the only negative. Same with adding after market suspension, engine mounts, etc. Those really help more than the negative which is vibrations. They won't be too bad as many have them and can feel a difference in vibrations, but the positive outweigh the bad.

Its like adding an exhaust and not wanting sound, or rims but want a stock feel, or lowering the car but want a smooth ride..always a negative with a positive.
