Independent Rear Suspenion Kit?


Jfast

Recommended Posts

One member has installed a Jaguar IRS, but I've no idea how much engineering went into it.

To the best of my knowledge there's no bolt-on kit available. It only takes engineering expertise, time and deep pockets to design one.

Try Heidt Automotive in Lake Zurich IL. I don't have a number, but the Hot Rod Power Tour has stopped there twice in the past two years. The made up a IRS for a Nova on one of the recent Phantom Garage episodes. The width on a Nova has got to be close to an Avanti.

I have seen one or two that used XKE components, however the installation raised the rear of the car. Ride/handling may have improved but aesthetics took a hit.

I think all XKE's had pretty much identical components regardless of year.

C4 Corvette Dana (36 or 44) with what the Corvette guys call the "batwing" fits inside stock Avanti rear track with some shortening of components and a little frame engineering. The C4 line (inc. ZR-1) and the Viper both used the Dana 44. I look at it like, "If it's good enough for them …"

This is the route I prefer, though I wouldn't shorten the Corvette stuff, I'd widen the Avanti's body with some bubbled fender flares (modeled after the Mid-Ohio endurance Avanti, which also used an independent Dana 44).

You might be interested in this site, they are building the IRS designed by Ford for the 1st Gen Mustang.

This was rejected by Ford when it was decided that it made no improvement (and was costly). The early

Mustang is the same size as the Avanti (some say Ford used the Avanti in some of their design) so this

should fit fairly easily.
