Appropriate Wheel Offset for 18" Wheels?

Hey Samy I'm now running 285/35/18 Hankook R-S3s on 18x10 inch wheels front and rear on my 1967 Valiant. I have the exact same front suspension as you, my 18x10 front wheels work with both a +24 and a +30 offset. I've obviously done some fender massaging. In the rear my 8.8 is a little wider than your rear, 59.5 inches, but the perches remain in the stock location. Again with fender massaging the 285 Hankooks on 18x10 with either a +24 or +30 offset work.

I have to wait another week or so before I can mock up the wheels on the front. I'm kind of on hold till next weekend as I'm settling into school right now. I think 275's should be fine for now. I'm assuming these wheels are about a +24mm offset so I guess I was right when I said I needed something around a +19mm offset. I still have to check the other side. I really like how your buddy did your rear fender flair though.
