How bad is it to use Aluminum subframe bushing replacements on a daily driving s14 Vs. Polyutherane ones? I ask because I am bringing down my subframe to replace my busted fuel tank so I want to take advantage of this opportunity to replace the subframe bushings.

Some aluminums just seem easier to install since you dont have to deal with ripping the worn out ones from the frame. I hear the aluminums, since they stiffen, will help with drifting but how bad are day for daily driving?

Be careful it will rip through your subframe. If the bushing gives you a hard time, use a sawz-all or hack saw to cut through the bushing. It will come loose. For install, I took the spacers to Broward-Bolt, and got the biggest bolt to fit throught the spacer, and a washer and nut to go with it. Position everythng on the subframe and tighten away.

I have also heard they make lots of noise. Is all this true?

Please advice. Click to expand.Why dont the spacers hold the subframe tight to the chassis? Did you support the subframe with a jack while you torqued the nuts with oil in a criss cross pattern? Are the nuts bottoming out on the shank of the stud coming down from the body? I replaced my subframe bushings with energy suspension polyurethane z32 bushings, you have to cut a little bit off the height to make them fit correctly but its not a big deal, a razor blade will do it, no issues. Ive never driven or ridden in a car with solid subframe bushings.

You have to take out the old bushing and its metal sleeve to install aluminum and polyurethane bushings. Aluminum Collars I believe are installed with the original bushing in place. Why dont the spacers hold the subframe tight to the chassis?
