Hey guys, 
Hey, I know this question has been done to the absolute FCUKING DEATH, but I've been getting some conflicting information.
OK, I have a GSi. At the moment, the suspension is all standard GSi components. I probably would want to uprate the suspension a bit further, a bit down the track, but I wanted to wait to see how she sits on bigger wheels. If she's a bit high, I might take her down a few cms (not much).
Now, alot of people on Corsasport agree that the best offset for a 17x7" wheel on a Corsa B, is ET45, yeah?
I've been speaking to a few guys at tyre shops, who are all telling me that if I was to go to a 7" wide wheel (1" over the standard 14x6"), that I'd have to come down to approx an ET40. I have also been shown the fitment book for Momo, which says it should be ET38.
Can anyone with a Corsa B, with 17x7 ET38 wheels, tell me what their experiences are? Input from anyone else would be appreciated too. If I need to do arch work, that's not a worry.
Any help . . .
Thanks guys.

ll mate u still need an offset of around 45/49 (even tho proper vaux offset is 49)
many many many people have 17x7, but nearly allways go for an ET45ish, and u should be able to drop it 40mm with minimum arch work (ie take out inner arch bolts)

Thanks for the quick reply mate.
Really dude? Cos a guy I was talking to today, reckons he had a customer recently, and they had 18's on a Corsa B with ET35?
Sorry to be a pain in the ass, but exactly why do we need such a high offset? Is it just because of those little hex bolts? Cos if we COULD get ET38's on, they'd fill out the guards a bit better. They wouldn't burrow back into the wheel arch as much, if you understand me.
Thanks mate.

cos the vaux off set is ET49 mate, im pretty sure vaux made it 49 so that if u get a puncher at high speed u can still control the car
i have 18s on a ET42 offset, but his is because i have coilovers and a wide arch kit
ET49 will give u the best handleing in a corsa, if u want to fill ur arches alittle more then id say ET42, but u will have slighly more problems when lowering it due to the tyre catching the arch

i didnt think it was safe to machine the rims that much, that would be taking about 7mm off, doesnt it weaken the bolt face or summat

Thanks for all your help guys.
The wheels that I've been lookin' at DO actually come in ET45 (which is what I thought I was supposed to get), but all the salesmen kept telling me to go for ET38, as did all their fitment books.
But if anyones to know, it'll be you guys hey, cos you've actually fitted the wheels and experienced the problems. I'll just tell them that I want ET45. It'd be safer that way anyway, cos if I have any problems, I can use spacers to come down in offset.
Thanks again.

Cool. I'll post some pics when I get them on, so you all can see. I don't want to say what wheels they are, but I'll say that I'm almost certain that nobody has them on a Corsa yet.
Had them sat up against my car yesterday and I almost jizzed in my pants cos they looked so good!

Not too sure yet mate. I want to see how she sits on 17's, and then I'll decide. If I think it looks OK, I may not even worry about dropping her. I'll see how we go.
