so I want new mounts on my wagon and have not found any options that really look good... untill now.

ok short story to explain the train of thought.

when driving my wifes WRX I cant stand the drive train slop you feel when getting on and off the throttle. I never have been able to accept that in car designs. my wagon has it a little bit but the WRX is bad. no there is nothing wrong with the car. I have felt the same thing in most all newer subarus I have driven(WRX, Forester, Legacy)

so im looking at the STI mounts they sell to make people like me happy. and when looking at the pics of them it occurs to me that they look verry similar to the EA82 mounts I know so well. I doubt they are a bolt on as that would be way too easy. but I think they may me installable with some minor modifications.

so Im thinking that I will order a set for the wifes car to see if she likes it or not. I can measure them before installing them. If any one is interested or has tried this let me know. any input would be helpfull

Are you talking about motor mounts? You never specified what kind of mounts in the whole post.

sorry thought the title of the thread would explain. I am considering using the STI motor mounts that are sold to fit 02 and up WRXs as an upgrade. they also sell a upgraded tranny mount and pitch stopper too. those may also be made to fit. right now I think I will stick with swaping the motor mounts.

the problem is if you use the sti mounts, your motor will sit up, about an inch. messing with dual range shifters, and putting a big angle on your cv axles(yes, i tried it)
so, i took the big mounts, threw away the center rubber part, cut alot of crap off of it with a sawsall, and only kept the part that bolts to the motor(mines an xt6 motor in the little car), then used the ea81/2 lower part.

if you want, send me your mounts, and i will make them solid, and unbreakable for 5 bucks. or bring them to a shop, and have them weld a steel plate to the side, making the rubber useless. the only thing i notice from the solid mounts is a bit more vibration at idle.

on cars that i have solid motor mounts, and rubber tranny mounts, i ratchet strap the tranny to the x member, makes a huge diference for the slop, just by itself. but on my hatch i have solid motor, and tranny mounts.

so if you didnt sift through all that crap, the sti mounts would be a waste of money for a guy with an ea81, or ea82, or er27, in an ea81, or ea82 body. too tall.
modify the stock ones =]

ah so they are larger huh. dam that sucks.

I have already messed around with welding the mounts(got my own welder:)) but the shake at idle with A/C on sucks. and yeah I did have the trans mount tied down for a while. that helped a little.

well thanks for the input thats exacly what I needed to know.

my next try will be using chain.
take two links, linked together. weld one side to the top plate, and the other to the lower plate... at idle it will move just enough, but when you torque it the chain will limit its slop.

:lol:

that makes me think about the first rally car I crewed for. it was a little RX7. the guy had a chain bolted to the motor and down to the chassis as a pitch stopper. the guys at the tech inspection loved it.

but seriously that may work as long as you can get a decent weld on there. My method was to run two rods thru the mount and weld both ends in place. that only lasted a week or so. still holds the mount together but does not limit the movment.

Welding them will cause premature wear of engine and gearbox bearings, spose you know that though?

ummm ok.

not quite sure how you found that out.

dont know of any facts to back it up.

please enlighten us if you ave some real info here. I see no reason why it would increase wear on internal components. shaking the car more definatly has an effect on the chassis I agree but motor/trany wear? need proof. never heard that before. tractors and othor heavy equipment often dont have rubber mounts guess they never heard this when they designed them.

the rubber mounts are for the comfort of the general public. there is no way im putting more stress on stuff, cuz its not moving around.

it makes the car stiffer, as the motor becomes more of an integral part of the frame/unibody of the car. the only thing im worried about is pulling the unibody apart.
