After speaking to raceways of donnington (http://www.raceways.co.uk) for some quotes, I’m surprised at the cost of both of my chosen designs (nowhere near the £1000 mark I paid for the wheels on my old buggy).
I have also been making sure that the wheels will actually fit to the car. Ideally, wheels want to have a stud pattern of 4*130 to stick straight onto a beetle, but this size is extremely rare with big wheels.
The next option is to see what custom discs are available for different fitments. An ideal place for this is Machine7 (http://www.machine7.co.uk) who supply custom discs exactly for this reason.
For american wheels, the best pattern to go for is chevy 5 stud (5*120.65) and luckily both wheel designs have a range including this size.
Something had been bothering me about the design of my first choice wheel:
The picture shown has a 6-stud pattern and I can’t quite see how a 5-stud would work.
After some more investigation online, it transpires that the wheel has a different design for 5-stud, which in my opinion is nowhere near as nice as the 6-stud.
This has made my mind up for me, I will be going for my 2nd choice of wheel from Panther (EMR-359), but unfortunately I will have to go with a 15″ diameter on all sides as this is the only size they do with a chevy stud pattern.
