For those that are not aware there are very few options for wheels for the early model C4 Corvettes.

Unless you get a set custom made, there is not a great deal to choose from.

The latter model C4s' (88+) share similar offsets to the C5 and C6 Corvettes, needless to say with such a massive aftermarket available for these late models it isn't hard to find something to suit your late C4.

You could get away with using wheel spacers to fit the later model wheels on the early C4s, however I'm not keen on this idea as I much prefer the wheel to bolt directly on to the hub.

So after much searching I came across the new (2010) ZR1 wheels. These wheels are available in 19x10 and are made in the correct offset to suit the front of the new ZR1 which just so happens to have an almost identical offset as the early C4s'.(only 2mm difference!).

I did a bit of searching around to see if anyone had tried fitting the 19" Zr1 front wheels to their early C4 but was unsuccessful so I figured I'd give them a go.

After punching in the numbers in to the wheel/tyre calculator above I found that the 19x10 wheels fitted with a 295/30/19 tyres should fit perfectly.

In actual fact this combination has only a 1mm difference in rolling diameter compared to the original combination so the gearing should remain the same and the speedo acurate.

So after buying these wheels late last year I have finally got around to fitting them on.
