Anyone have them on an ls1 and had problems with false knock or more vibration problems? Also will this help my pacesetter y-pipe from hitting the floor from the engine rocking to the side under power?

yes, it will help keep your y pipe from hitting the floor. as far as the false knock, i don't see a problem. not saying that it couldn't happen, but i haven't run across that yet. I would think that there are a lot better mods to get for your car (according to your sig) than solid mounts. They are one of my last mods when i was trying to squeeze every bit out of her. Are these for you or are you just wondering?

You might be just as well off with Poly mounts. Little search will get you a lot of information on this topic. Check in the suspension section too.

Just get poly mounts. They will work just fine, and you won't get any false knock.

yes there for me, but its about to get cam, heads, and a built trans with stall.

I have a mildly agressive set up and the poly mounts are more than enough. I read in the handling section that solid mounts introduce more stress on the block. I haven't seen any proof that it causes damage, but it seems reasonable that it could.

Unless its a full on race only car, skip the solids and go with poly mounts.

I got solids in my car and it feels BAD ***! it literally felt like i hade added a torque arm when i installed them. My exhaust hugs the underside of my car and never hits it either.

I will be installing the poly mounts in mine. The solids will probably rattle your teeth out..

Get the prothane mounts, I just put mine in yesterday...kind of a pain in the ***, but doable in a garage. My car is off just now to T.J.'s house to get the exhaust put on. Should be started tomorow night.

vroom vroom...

rubber to poly motor mount switch + header swap = easily installed mounts + headers that don't bang

that is a large misconseption. If you drove or rode in my car you could never tell it has solid motor mounts.

and why would goin solid give you more performance anything? (i'm asking, not tryint to be a ***) I thought taht a solid owuld only stiffen up the front and use the torque to help lift weight off the nose when accereating.

Solid motor mounts are just like a drag sway bar, subframe connectors, drag torque arm, drag LCA, poly trans mount. Anything you do to stiffen up your drivetrain/chassis is going to help you put more of your power where it belongs to the ground.

Hey guys, I have a largely stock engine and a manual tranny and was wanting to get rid of the shifter movement under acceleration. It moves over to the right about an inch it seems and drives me nuts. I was considering replacing only the drivers side mount with a poly one, but am now considering a solid mount. Since the passenger side would be stock, the solid mount shouldn't stress the block or anything like that, but may reduce the engine twist a bit more than the single poly mount.

Has anyone considered taking an a used motor mount, burn out the rubber and then weld the whole thing togrther with steel plate? You'd have an instant solid motor mount for almost no money.

Or what about something like this?

When your motor twists you lose some of the power it is putting out. So there for the less twist the more power put to the wheels.

You left out the 4th dimension, time. You are only losing power while the rubber, or whatever, flexes. Once it has flexed to it's limit, all the power is transfered. But still, you will lose power on every shift and that adds up.

Hey those are the mounts i made.

JasonWW

iTrader: (2)

Yea, I like how simple they are.

Did you use an old mount to get the dimensions and mock up the new piece? I think that would be the easiest way to do it.

Do they work just fine?

Any tips if I try to make one for my drivers side?
