What will happen? Will the springs clank and make alot of noise? or will there be more road noise? Just wondering. I think I might for the hell of it just take them out for a bit. Since I have air tools and a lift and what not. IT wouldnt be to hard anyways. So what? whats teh side effects? thanks.

The front isolators are very thin. If you remove them the front of the car will be lower by about 1/8"-3/16" or so. The rear isolator is about 3/8"-5/8" thick and you will lower the rear of the car that much if you remove them. You will not find a great deal of handling improvement by removing them, but it will stiffen things up a very small amount.

You shouldn't have any clanking, but it may make a little noise when you first drive the car each time after jacking it up and sitting it back down.
It will transmit more vibration into the body of the car. It will also wear more on the mating surfaces of the spring pocket and spring. It may squeak too. If you do remove them I would recommend that you put a thick coating of brake caliper grease on the top surface of the top coil of each spring to reduce vibration, popping and squeaking.

Thanks man for the information. I already did the job already but I guess imma do that grease thing. Never thought about that. I was thinking about spraying a thin coat of rubber bed linning. In attempts to in a way be like the insulator. But not be thick and raise the car like them. Hmmm...and yea I dont notice any road noise or anything after taking htem out. OH well...

The good urethane spray bed liner might be a Good idea. That cheap trunk paint looking stuff wouldn't work too well.

The springs usually don't squeak for a while after removing the isolators, but after the mating surfaces wear together for a while and they eventually polish each other, then they begin to squeak. Caliper grease will prevent the squeak, and is sticky & thick and won't all squeeze out or wash away. The good bed liner sprays should work well too.

Why?

Replacements are cheap at the dealer.

The reason I took them out was to

1) lower the car more (which it did...the drop is noticible)
2) Attempt to make the suspension stiffer (better for drifting...stiffness is somewhat noticible but not super noticible)
3) just to try it for the hell of it.

I still have my stock insolators. So if ever I want to put them back I'll just put um back not to hard.

How thick are the isolaters actually? What if you slipped a piece of rubber garden hose over the first coil so it doesn't wear the pocket so quickly? And it would help with vibrations and noise to a degree also.

ok i would do that but i have struts in the front not springs i only have springs in the back so what do i do???
its a 86 z-28 w/stock suspension

RED IROC RACER, you have both, springs and struts in the front.
You have springs and shock absorbers in the rear.

Well I dont know exactly how thick they were. But the drop is noticible. Also my front lip was bending back bad over the curb when I parked. Normally it goes over but after taking them out the same curb pushes the lip back O_o

OMG i know i have springs in the front i feel like a complete moron i posted that question at like 3 this morning so i wsnt thinking strait but thanx anyways how long did it take to do yalls??
