That setup looks like the chassis end is just a lightweight bolt on bracket, when it has to support the weight of the car, plus the torque of the axle under drive etc.

Mind you, it looks like the rest of the chassis is fairly light gauge steel too.

Yeah I've got several questions about it too, it looks like the springs are very close to the frame rails. May just be the pic though. I like the concept though!!

That's a lot of twist on those little bolts! Looks like 3/8" bolts, maybe four of them in each stand? Pretty flimsy. But then, it isn't finished yet.

I put them on the frt of my 37 Pontiac but I am only going to run a inline 6.
I haven't driven it yet and the pics are just a mock/tack up so far.
I just like how it looks.

My 'Glass '27 roadster has quarter elliptics and is the best riding hot rod I've got.

Cool Quarter-Elliptic springs

Last year I helped my son build a fiberglass T-Bucket for a Senior Project at ASU as it had to be done in a timely manor he chose a simple car to build, him and his two class mates put in about 1500 hours during the design and build of the project. As a lot of the project was pulled from my stuff we used a lot of things that were different about how we did the car one notable thing was he chose to use Quarter-Elliptic springs both front and rear we used springs from a Suzuki Samurai (they are two inches wide) and as we were punting at the time as to the total weight (460. C-6, nine inch) we figured that the weight on the springs could be adjusted at a later date, The boys finished the car with about two weeks to spare (so they could concentrate on finals) the car was tested using accelerometers to check acceleration braking and lateral forces .88 accel .91 braking and .85 lateral (on seven cylinders,bad cam). During the design phase he learned a lot of people use quarter elliptic s as the lateral stability system IE instead of a panhard bar, springs are meant to do the work of springs and bend well up and down, not so good sideways. His car has Watts links both front and rear. My son also has a 2010 Mustang with a drag pac and the T-Bucket will out handle and out run it.
