What would be a good offset, I want the biggest lip possible, I want it to be as flush as possible
The tested and good offset is 38 for 10.5. Enkei PF01 is available. Decent price and excellent wheel. Front will need a 5mm spacer with wider tires and rear is good.
This is according to Sam Strano and Vorschlag on the forums. They both sell this wheel.
Vorschlag has done a ton of work with various wheel and tire sizes on their S197 race cars and has shared information via Vorschlags site and others. Call them for advice or Strano.
Almost right...Vorshlag doesn't sell the +38's, and they don't consider them to fit either.
A 10.5 needs to be 50-55 or so to fit in the rear.
