IRS driveshaft length?

Post by simonjrwinter »

Can anyone tell me the length of their shortened IRS driveshafts?
I’ve got the chance to buy a set from an AK and just want to know if they’ve been shortened by the correct amount for a Hawk FIA….

Inboard disc set up.

Driveshafts = 11.3 inches -- Centre to centre of UJ eyes -

Note - these go with the shortened wishbones provided by Gerry at the same time - these measure 11.8 inches along the tube section (not at yoke eyes).

If not paired, camber is likely to/will be affected.

But it depends of the wheels and tire size you will mount too.

Karl is running GH wishbones and 9.5" TRIGOS, which are too wide. He had to mill down the center.
