MGB body reinforcements for IRS?
Posted by: RDMG

Hi everyone,

I've read a lot about useful reinforcements of the MGB unibody frame when retaining rear leaf springs on a V8 conversion, but I haven't seen much discussion about reinforcements needed when using an IRS setup.

I'm planning to use a bolt-on Hoyle IRS assembly, which uses many of the factory rear suspension mounting points. However, I expect the stresses on the frame will be applied to different points, given the changed geometry.

Anyone out there have experienced to share?

Dave

Not sure any are needed. Have you read this?

On the Jag conversions I used a member which tied the two front spring hangers together and in the center butted up against the lip on the panel that forms the bottom of the driveshaft loop using a 1/4" thick nylon wear strip to handle thrust loads.
