Reply to "Swing axel or IRS"

I've done the swing to IRS conversion twice, albeit not on a speedster, but on Karmann Ghia's.  I think the handling is far superior and worth the undertaking.



The pictures are from my 1958 LowLight Ghia.  I also narrowed the control arms 1 5/8" per side to fit a larger tire under the fender.

DCP_0761DCP_0762DCP_0763I threw together a jig off a bare IRS chassis. You can buy these now from several places to make the conversion easier.  A jig is absolutely necessary to get the proper orientation of the IRS bracket.  Take your time when fitting the brackets to get a tight fit for clean welding.

100_0104I triangulated the rear section for strength and future attachment for a roll cage.  I incorporated new shock mounts in the cross bar.

100_0111Those a type 2 CV joints, as they are larger and stronger than type 1.  Axles were 16" that were narrowed 1 5/8" to fit the narrowed control arms.

100_0907This is how you fit a 205/65R15 under the fender of a Ghia. I think a 215/60 would have fit without issue.

Go for it Arden!
