3rd Gen Plebeian
1997 Plymouth Grand Voyager Rallye
I have 235/45/R18's on +25mm offset wheels, no clearance issues.
This is your max without major rubbing/ tire chew, assuming stock 6.5" wheels.i've got a question that you might know the answer to, i haven't really been able to find a solid answer for this
what's the widest and largest diameter wheel i can fit before it starts rubbing without any lift or spacers?
The transmission mounts and engine mount are bushing type. You could knock/cut the steel center of the bushing out of the rubber, cut some of the rubber out of the way, mount the steel center 1-2 inches higher/forward, and refill the bushing with low shore hardness polyurethane or silicone. The bushings are attached to the engine/transmission, and they hang off of the chassis through the center bolt. Puting the center bolt hole higher in the bushings will result in a drivetrain that sits lower in the subframe.I figured 30's were possible! With my rim choice I can't do it, too much negative offset running spacers to clear the calipers.
I need to do a front subframe drop/drivetrain drop to get rid of some CV shaft vibration. When I do that I'd like to scootch the front subframe forward a little, to make a little more room during turns for the front wheelhouse at the firewall/rockers. I can always trim the plastic bumper. May have to make a steering shaft extender though. Then I can use the aluminum strut spacers I have for even more lift.
I hadn't thought of that. The steel half of the mount could just be redrilled with hole for the center bolt offset forward and lower.I got a 3rd gen transmission mount today, with the shift cable bracket in case I need it. It was a white '96 Plymouth Grand Voyager handicap accessible van, so I got the front upper strut spacers too. 2 cars down the row was a Pacifica with brand new struts!! So yup, grabbed those and put the strut spacers on them. Now I have enough stuff to lift another van. I also got a steel wheel with a 30" tire on it, to swap onto a rim and see how it will fit/clear things.
The transmission mount body is steel instead of aluminum. Makes it easier to cut and weld if I have to modify it.
