Rears are fine the front offset is miles too low, your wheels will stick out about 20mm outside the front wheel arch.  I have 35 offset on my 7.5 wide fronts and they are borderline.  
If you are at Silverstone, you will see what I mean.  I am planning to have the offset on mine machined to 38 or even 40 if I can.
Some wheels have enough meat for you to machine the offset.
Remember you need a centre bore of 60.1 or some spigot rings if bigger.  My wheels were 57 centre bore so I had them machined out.  I know a good place for that except they are in Essex!
