Hi All,
I have asked a fair few in the know and nobody can tell me why alfa 75 2.5 (and the GTV6) were a 45mm offset and then when the 3 litre & twin spark came out it was changed to 30mm.
Would love to know what (if anything) changed with the front suspension or geometry?
I'm about to have some 3 piece wheels made up for my 2.5 75 and it would be a good thing to know the difference.
Any help would be greatly appreciated.
Having a guess I'd say tire technology, perhaps check the wheel alignment specs as well...
A slight variation in static camber and wheel width with a different/newer tire, even brand of tire could dictate a difference in offset.
For the record the basic suspension geometry is the same for all models
Calipers were different compared to earlier 2 litre versions
They changed the offset to fill the wheel arch flares better.
Twinspark and 3l 75 had flares stock, early 2.5 75 didn't

😂😂 thanks Duk!
Thanks to everyone for their responses. I believe the front calipers for the GTV6 and later 75's were the same. The wheel arch spats on the later 75's makes a lot of sense. Next step is to look at the caster and camber differences as suggested.
