Friend of mine is just about to get an MR2 turbo rev3 import.
Therefore it will come with japanese asaki ditchfinders
He wants new wheels for bigger brakes anyway.
From research on the MR2 forums it seems that 16s are the best 'go' wheels rather than 'for show' wheels.
The PCD seems to be 114.3. What is the offset? We are hearing anywhere between 35 and 45????
What front and rear tyre sizes are best and what wheel width for handling?
Also any suggestions on wheel choice pls?

Thx in advance oh all powerful ones
