Thanks guys.
The gap between the front tyre and arch is greater than the gap between the rear tyre and rear arch but it's perfectly balanced as it is now. I could lower the front for looks but I prefer better handling over looks as it's my daily.
I will lower the car all round some more though so the rear tyre just sticks under the guards (they are rolled) and then there will be a 1 finger gap between the front tyre and arch.
Also, just bought a K20A so working on the conversion soon! Will keep everyone up to date on the progress
