Be VERY careful when installing them. The instructions state that it can cause CCW. I always thought it meant "Counter Clock-Wise", but after further research, I find that CCW means Compulsive Cam Wiggle. If you develop CCW, it can seriously damage your Finiker Link. Finiker Links are such a pain to replace, too. I usually have to use a Metric Adjustable end wrench (also known as a "Several Sixteenths") And then back it up with a Whichita Whacker. The best material to use when fabricating Finiker Links is Unobtainium, but at nearly the price of gold these days, do what you can to avoid damaging it. By reducing CCW the car will run smoother and make a measurable amount of power increase as measured and verified with a calibrated "butt-dyno". (though, you REALLY don't want to know the calibration process.
)
