I wanted to share this for anyone who was looking to do an IRS swap.
Its possible this is an issue in the 99+ cobras but the flared fenders mask this subtle issue that in no way affects drivability.
alright so as many of you know I slammed this 99 cobra IRS into a 97 cobra. Allegedly this is nearly a bolt on affair. That much is true if you are happy with the way ford does things. Short and sweet? the front holes for the IRS are such that the IRS, when bolted in, is a little to the driver's side. Not enough to get out of alignment spec but enough to necessitate a spacer. I thought, perhaps, the whole subframe was just a little to the left but today I noticed the passenger tire is about 1/4" more rearward than the driver's side.
so, from the factory there is a bit of play in the IRS and one fix for that is to drill out the holes for 9/16" bolts. Solving the movement in the IRS cradle may have introduced a new issue of precisely lining up the thing... wrongly. solution? wallow out the front passenger bolt some measurement so that the whole cradle can rotate a hair.
This could solve a couple things.
1. the need for the spacer on the passenger side (5mm)
2. the need for the passenger wheel to move forward some
3. the need for the driver' side to move rearward some
has anybody noticed this besides me before?
