alright all, after some consideration have just got some used 18s for my vts, they were previously on a astra h, they have an offset of 42 so i have a discrepency of 17 mil. will i experience any problems fitting 20 mil spacers theoretically bringing my wheels 3 mil outwards? also how do you calculate what length bolts to use? thanks.

Make sure you use 'Hub Centric' spacers and not flat ones: - Click Here -

The PCD of the studs/bolts will be different between Astra and C4.

I am almost positive that the Astra H uses a 5 stud bolt pattern as well.

Some of the older Astra G's use 4 stud, a few use 5 stud there as well.

As said by Ham unless they are multi fitment wheels (usually have 8-10 bolt holes), then they are going to be 4x100mm not the 4x108mm the C4 needs. So you are going to need an adaptor spacer not just a regular spacer. To go from 4x108 to 4x100.

I only go off what the guy said. Yes they are multifit. I almost just had a heart attack when i realised that i never actually physically checked the pcd. I am relieved that they are 4x100 and 4x108. (dont know how i would've explained that one to the mrs) Phew!
Now I have an issue as to which spacers to use. It'll be hubcentric 20mm, but why are there two types?? confused. one type bolt onto the hub and you use original bolts to mount wheels on to spacer. other type you just go straight through the spacer with longer bolts. Is one kind superior to the other?? Cheers. Mike.

Personally prefer the bol to hub type.

Mine were also converters so changed from bolts to studs which makes getting the wheels on and off a bit easier.
