Slow and low!
Hey folks, I'm currently looking at a set of wheels that I'd love on my astra.

The wheels are 18' 5x112 8j et45 with a center bore of 73.1

Now the astra is 5x110 preferable et37-et42 and its center bore is 65.1

Is there a way to get these to fit?
I'm hearing things of spigot rings/wobble bolts/spacers.

Anyone know what the score would be? I'm not too clued up on this stuff.

5x112 To 5x110 PCD Adaptors won't work as they will be maybe 20mm thick and give the totally wrong offset.

Wobble bolts will work as they allow 1-2mm of adjustment and you only need 1mm.

You will need 73.1 to 65.1 spigot rings like these

With spacers it will depend on brake caliper clearance and how you want the wheel sitting in the wheel arch.
If the current wheels on the astra are et42 then the new wheels at et45 will sit 3mm further into the wheel arch.
If the current wheels are et37 then the new wheels at et45 will sit 8mm further into the wheel arch and probably hit the front brake calipers.

Are these new wheels local, could you test fit before you buy to measure up?

Hope some of that maybe helps.

Cheers

What width and offset are the wheels that are on the car now and you can work out how the new wheels will sit better?
