will a rear end from a 3rd gen (iroc) bolt in to a 4th gen or does it need modifications?

 

There are differences in the brakes and parking brake, but they are otherwise the same (with the exception of the 9 bolt)

 

third gen is 4 inches shorter, so wheels won't fit........

 

different offset rims should fix that or some mini tubbing ... is it a direct bolt in tho ?
thanks for the reply too.

 

OPS! my bad

 

The spring, shock, torque arm and panhard rod mounts are identical. The brake mounts will be different. The e-brake provisions will be different. There will not be a sensor (or sensors) for ABS/TCS. The brakes may be so far inboard that you could have problems with them being too close to things like the jounce bumpers, although that's maybe overly cautious.

There's a dimensioned drawing on the Strange site that shows the difference is 3" in overall width. You could use a 1.5" bolt on adapter (like the ones from Skulte Performance, not smiple plates) for the wheels.

Fred according to this, skulte makes the 2 inch adapter for that purpose...

 

I understand that the difference may be 2"... I'm just pointing out that when Strange builds "bolt-in" rears for the 3rd Gen, they make them 3" narrower than the ones for the 4th Gen. It would seem worthwhile to investigate the correct number.

 

the difference is between 3" and 4", but if he does it, he will need to verify on the car, for wheel fitment
