Modified IRS K-frame for Lowered Cars

Apparently Star Performance use to modify the rear to correct the camber back in the day. I knew a guy with a VT that had it done.

Yep as Jaba said, they are so you can run 345 wide tyres.

Sorry for the delay, ive attached some pictures.

Lower mount for coilovers has been extended with 4340 chromoly, it has been welded to the original mount and tapped for longer m14 bolt. This is in a ute so the upper mount bolts in place of the factory shock mount.

The car feels heaps better than the original setup and the shock/spring is now behind the diff so helps with weight transfer.

Looks good but it looks like you only linked thumbnails. Maybe someone more in tune with this forum can tell you how to link photos properly.

I assume thats installed in your VU?

Yeah sorry posting off the phone so bit limited and rushed.

Yep this is in the VU, I’ve used a VY sedan subframe and control arms as you can get the shocks more upright with the extensions then the ute control arms, also you can use toe rods which I’ve made out of chromoly with rod ends.

Do you know if the same thing can be done with the VP/S subframes

Can’t see why not, the subframe is similar, but the control arms are different.

Not sure how much clearance from the mount to the body the vp/s has though. You will need 50mm from the centre of the original mount hole to the body at the lowest point minimum.

Hey Brad, great mods, given the interest in this thread, if at some stage you can re-post those images full size would be great.  This is the link to how to do it if your not sure.  http://www.commodoresplus.com.au/forums/topic/posting-images-using-photobucket-attachments/

No problems.

I have all the measurements and most stuff drawn on cad, so if anyone needs info just ask.

Curious what kind of welder/rods you used for that?

I have a digital ac/dc tig, filler rods are Cigweld high test rt60 using 2.4mm 2% thoriated tungsten sharpened to a long pointed tip, I use a foot pedal so set max amps to 110.

Awesome info thanks Brad, I’m a total Muppet on Steel so having a good starting point will help!

Nice tig welding is like looking at mechanical porn…

Thanks for the nice comments fellas.

So these cradle extension boxes are they purely for running coilovers/tubed control arms or could u weld them in and have the rest stock just lowered to help with camber?
