    I am in a grove. One of my wheels needed a touch up.

    What are the measurements/offset of the base wheels?

    Base is 18x8 and 44 offset. The Brembo wheels 19x9 and 42 offset. Then 20mm spacer=8.5mm clearance which is a lot. 17mm Spacer = 5.5mm clearance which is just right and 15mm spacer is 3.5mm clearance which = absolute minimum.

    Thank you for your help.
    I successfully got em mounted and working with a 10mm spacer. I may increase it to a 11 or 12mm for peace of mind as there's only about 1-1.5mm of clearance with the current spacer.
    I'll attach photos as well 20210206_172847.jpg

    In terms of bite force, Yea theres DEFINITELY a noticeable difference. The weight shifts much more forward under hard breaking (when bedding brakes, all my stuff went flying when I slammed the brakes)

    Looks good. Is this the 14” set up and what size wheels are you running?

    Remember I did all four wheels. I am using 13.8's GT500s in the back which might offset the weight shift a little. Yes, 1.5 mm is not enough with a 10mm spacer. A 1/2 inch spacer would work perfect. Interesting that you need a 1/2 inch or 12.5mm spacer with second gen PP wheels. With me it's 17mm spacer with first gen base wheels.

    Because of the spoke design. They’re more concave.

    I was thinking all along that those PP wheels of a second and third gen cars would fit over the Brembo brakes of the Gen 1 cars. I guess not. Using Second Gen PP wheels, you need a 1/2 inch spacer for the fronts vis 17 mm for the Base Wheels. For me I ordered 2009 GT 500 front brakes and 2014 GT 500 back brakes. Then one of those aluminum Ebay adaptors from a guy in NC. Nothing fancy. Just Raybestos stock street parts from RockAuto and the Calipers with no core charge from Amazon.

    Then 17mm spacers from a aerospace company in LA.

    Ford designed the S550 to have the hub stick out further like by a 1/2” so the wheels can stick out further and away from the calipers. Pretty much like using spacers. They also don’t have to design wheels with a lower offset or design the spokes to be concave. This is why S550 wheels require spacers when using them on S197 cars.

    and a false report that S550 wheels do not fit S197 cars. True to a point for only Brembo to Brembo. S550 wheels well fit fine on a Base Non-Brembo S197 using S197 lug nuts. You also can NOT use S550 rotors on a S197. Then there are spacers with S550 lugs that will fit S197s using a combo of S197/S550 lug nuts. The Poke look is all the rage with the S550 set and you get that with 1/2 inch additional spacers on top of the standard Ford Thinking.
