Independent Rear Suspension Forum » Are there performance parts for my 65' Jaguar 3.8s IRS? » 5/17/2015 9:33 am

I have seen some fabulous work here for using varients of the Jaguar IRS into non Jaguar cars.  What I have is a 1965 Jaguar 3.8s 4-door sedan with the earlier IRS that came stock but I am running a 450-460 HP GM LS1 so I just want to find ways to make my stock setup stronger.  I assume from my visuals that the weak points are the stock Hub Carrier, Wishbone, and maybe Half shafts?  Does anyone make performance parts to make my setup stronger while keeping as much of the stock setup as possible.  What I have done is add coil overs to the stock IRS and added some simple plates to the Radius Arm and Cage.
There seems to be many custom fancy setups to use the IRS in other cars but I cannot find out parts to upgrade the stock IRS if I am keeping in the Jaguar it came with?

That is so creative to put the battery there!  Is it hard to remove it?  I will have to look at my Jaguar to see if there are spaces like that available as I am putting a crazy mobile office with dual batteries so if I can place a battery not in the trunk that would be so cool; PS there is likely no room in the engine bay as the big v8 appears to suck up all of the space in the Jaguar 3.8s?

so I might need to wait until we are closer to having the car completed then? 

right  now we are working on making the LS1 fit into the engine bay, then we remove the motor , then the car goes to the body shop to strip the undercarriage and POR-15 the botton and engine bay & paint the hood, then back to our shop to re-install the motor/trans, then upgrade the front brakes to Wilwood 4 pistons and change the front to adjustable coil overs like we did in the rears, then put the new seats and interior back into the car.  Thus until we get the car back and reassemble it, we will not have the proper four new rims/tires and new front suspension to allow us to get the car aligned. 

I appreciate everyone's help as I know enough to decide what I want but am having a shop install it for me so any helpful instructions to give them would greatly help.  I have just sent my request to "Mickmate" and I hope he can provide a kit to work with my stock Jaguar!!!

Here are a few pictures of the project car which I hope can be a daily driver in a few months with your help!

Ralphy & Daze,

Thank you so very much!  I will contact him as I guess I would need to measure where to mount the links to if he does not have a set up already designed for a stock Jaguar 3.8s which was in production from 1963-1967?

Have you found this to be a reliable fix for the weak design of that hub carrier?  Does drilling those mounting holes weaken the hub carrier or have you found it to be reliable for years?  My Jaguar will have about 450 HP from a 5.3 liter LS1 GM motor.  I do not plan to jump on the throttle too abruptly as I was worried that the hub carrier would want to twist since I am stuffing 17" 245 tires on the car on all four corners. 

Those pics looks so cool!  I knew American inginuity would come to the rescue by having somebody finding a way to improve on this design flaw.  So most of you are using this suspension on Cobra's right?  I think there is a market for this same piece for anyone wanting to make a performance or race car out of a Jaguar 3.8s, or any of the two door Jag sports cars as they all use this same rear suspension.  I was amazed that I think I am the only person whom realized that you could use custom off-set rims to stuff big 245 tires on a 3.8s eventhough the body style has about 1/4 of the wheel covered by the fender.  I guess after this post being my second one I can then post a pic or two?

I am building a 1965 Jaguar 3.8s 4 door sallon with an LS1 and was worried about the hub carrier twisting with the power.  I have welded bracing on the control arms and basket that hold the rear end, etc. but now it looks like the weak link is the hub carrier and after many searches I found your great forum!  I read some postings showing the watts link made to mount onto a stock Jaguar hub carrier.  That looks like the perfect addition to my project to help protect the rear suspension from breaking. But after searching I cannot find out where to purchase it?  Can any of you help me?

thanks in advance
