I would not go wider than a 215mm.
Can I just make a couple of suggestions to make your use of the board easier?
There are sections of the board for questions about different parts of the car. There is one section for questions on wheels etc. Use the correct section rather than "General Chat" so that others can refer to the answers in future.
Speaking of which. If you look in that section (or use the 'search' facility) you will find that this question has been asked before (I think?
) so reading that would have saved you having to ask in the first place!
The good thing about this board is that most of the common questions have already been asked. It is just a matter of finding them. That is why it is better to have everything in the right section of the board.
I am starting to sound like some kind of school teacher or something aren't I?
OK one more thing and I will shut up.
Don't write in CAPITAL LETTERS! On the Internet this is like shouting and it makes what you write much harder to read.
There. I promise not to say another thing!
We would love to see some photos (in the photos section!
) of your work and hear your story.
