I had a few good hours on the car today, I have been putting together my own rear tubs to fit the extra rubber in on the back. Started by removing the rear quarter to open everything up:
And have a good start on the new tubs, I had a little trouble getting the radius of the two halves to line up but with some patience they are starting to come together nicely.
Here's a cool 'cutaway' view of the rear of a P1800 - with some new components. Rear brakes are 13" Wilwood, calipers aren't in yet.
I set the suspension up and put it through its travel to get an idea of required clearance. This is about 1 inch above ride height.
New brackets for the tub and deck support.
And the clean radius for the new wheels
I have some work left to do on the tubs and opening the wheel arch around the front of the rear wheel.
Today was a good day.
