    Just finished installing my 2-post lift and getting ready for the 30k major. Where do support the ass end? I set the jack points just before the 6 large bolts on either side of the engine cradle but that leaves the whole rear end unsupported! When I engaged the lift a bit to test I notice a bit of gap starting between the door edge and the rear quarter? Is this gap normal? This is lift stuff is foriegn territory.

    For full engine subframe removal the rear lift points can't be anywhere other than just before the subframe-mainframe merge point on the mainframe side. Is this correct? I just cant get my nerves past the body flex between the trailing edge of the door and the leading edge of the rear quarter panel... I can see the tb not having this issue but the targa has much less structure. Anyone? Thanks.

    Troy,
    I know the feeling... it is always a test to get a car on the lift the first time. It took a bit of searching, but I know there are some pictures of 348's supported on the lift. It took a while to get comfortable with my 355. One thing I have heard of people doing is putting the car on and supporting the rear subframe with the lift at first. Get everything done that you need to to actually drop the motor, then go back and mover your lift point, now holding the motor and cradle on whatever setup you are going to carry it on. Then lift the car off the motor.

    It is certainly possible to dump a car off the lift, so be careful - safety first!

    You raise a valid point. It's a precarious arrangement but really the only way to get it done.

    You can improve a bit by removing the rear wheels as soon as you clear the floor.

    +1. Some shops also add weight (approximately 200 pounds) to the front boot. It is also probably a good idea to invest in at least one adjustable tall floor stand, like the kind used by exhaust and transmission shops, since you have your own lift. Be careful!!

    Well my mind has been here - I think you are completely right. I am not a structural engineer but dead, sustained pressure on the chasis/body at the floor-rear quarter junction can't be good. I think I will be going the extra distance and doing this extra step. Thanks for your response J.

    Aside from safety/car falling issues, do you guys worry about damage from excessive body flex (I have the TS not the hard top)? There is approximately 1/8" extra gap between the door and the rear quarter panel when the car is lifted. I have the jacks as close to the subframe main bolts as possible.

    NO, leave the battery in!! You want to INCREASE the weight in the front of the car to counter-balance the engine weight.

    Oh, I have a '91 - the battery is in back. I know what you are saying however. Thanks for the help - I'll be posting pics of my 30k soon.

    Sorry, Troy! I just noticed you have a 348. Hope everything goes well and best of luck!

    I've also been giving a lot of thought about getting a 2-post lift. Please post the type you bought and your impressions of how it works. Thanks!
