18'' Wheel Question

[Tattooman]

got a 1995 calibra dtm. question is, will 18'' alloys go straight on without arch work, and if so what offset am i looking at?

[Jhonno]

hmmm good question

think they might need a tiny bit of coaxing but not sure

offset erm... 45mm?

I know someone who put 18" Kahns on his Cally on a 45mm offset wiv no mods I think.
Rotten sod didn't swap them with me when he sold the car...

I know that 215/35/18's on a 7.5x18" rim with an ET45 dont need arch mods on a cav on a 60mm drop.

This is true but bear in mind Cavs and Callys have different arch shapes. The Cav ones come straight down and then flare out round the wheel so they are a bit narrower. The Calibra ones just come straight down without the flare so they have even more room than a Cavvy.
Therefore if they fit a Cav they will certainly fit a Calibra.
