Good point. I was already thinking about taking the front wheels off at the point in time when I'm ready to lift the body away, just to reduce the weight over the front lifting points a few by a few KG, especially since I've run the fuel tank down to nothing and am planning to drain whatever is left to pull the fuel pumps.
Does anyone know a place where the rear of a 355 can be lifted so that both wheels can be removed? I need to do the final exhaust adjustments on my car and it would be ideal to get rear of the car off the ground just enough to remove both wheels, pull the liners, and get access to the cats/header junction. Is it safe to jack it with a floor jack from the rear crossmember (red circle in @kenneyd's pic) if I put a 2x4 across the entire crossmember to spread the load? It's gonna suck to have to go side by side adjusting little by little.
If I lift using a trolley jack I always use the point circled in red in kennyd's photo. Use a decent rubber pad so as not to dent the reinforcement fillets on the cross beam. Do not be tempted to jack on the cross beam that runs under the gearbox. It is not strong enough to take the car's weight without bending and touching the gearbox.
Do you mean lift it on the gearbox mount (place a block of soft wood or rubber under the mount), or on the seam inboard of the mount? It's amazing how little info there is online about something that (to me at least) is rudimentary.
I mean on the joint where the cross member bolts to the engine cradle. That point is very strong. Exactly in the centre of the red circle on kennyd’s photo. I don’t jack from below the mount.
If I am just doing tires, I will use the factory rear jack points. I'm sure that 'red circle' in my picture is very strong, but I've never used that to lift the car more than a few inches.
I've got two floor jacks, to hell with it, I'm just gonna lift it with both. 20 years of 911 ownership spoiled me -- just put a jack with a piece of 2x4 under the case seam and the car is in the air.
Umm... why rely on gravity alone to keep it where you want it? Why not simply run a pair of Aerofast webbing straps from the arm on one side, to the arm on the other, with the appropriate protective padding and gently rachet the whole thing snug? (Not an owner (yet!), but an enthusiastic reader of this 345/355 forum, so I welcome your constructive feedback )
I have one of these knocking around for just such an emergency............. https://www.amazon.com/Stark-Underhoist-Tripod-Capacity-High-Position/dp/B07P629X9W/ref=sr_1_12?dchild=1&keywords=tall+support+jack+stand&qid=1613592026&sr=8-12
I use this, extremely handy for pretty much everything https://www.amazon.com/dp/B00AHIWN78/ref=cm_sw_r_cp_apa_fabc_2WKF9FD2WW1F4B9D76VF
These are the spots I use with hockey pucks and two post lift. I put small paint spots on the car to remind me Image Unavailable, Please Login
