Your brains are needed!

I have just bought a lovely set of Porsche design 90's, with a offset of 55 at the front and 52 out back. The problem is that I have no idea how much they need to be spaced out by. I know that the ideal offset is about 35, so would 20mm adapters all round be a safe bet? Or do you reckon that the adapters would need to be smaller/larger?
PS, anyonw know any decent polishers in the Luton area?
Cheers guys!

Blatant cut and paste from an earlier posting I did
ET is the distance in mm from the centre line of the rim to the hub mounting face
so the higher the ET the further in the wheels will appear if you keep the same rim width - obviously if you increase the rim width the effect will be reduced but you run the risk of fouling the strut.....
The lower the ET the further out the wheels will stick out if you keep the same rim width - obviously if you increase the rim width the effect will be even greater but you run the risk of falling foul with the boys in blue.....
I've a web site link somewhere that helps you compare all the wheel dimensions and specifies the clearance reductions v std wheel - this way you can measure up your std clearances and then know what you have to play with...... its a bit rough and ready but it works for me
Rough and ready one - I had on this PC but it's better than nothing

For Tyre sizing and profile changes when you go up on wheel size

When you know what your clearances are

Can't find the best link yet - the one that does it all Its on my home PC Somewhere
