Anyone used spacers on Radir Tri-ribs

Probably going to get slammed for this but I ve got Radirs for my A project and they hit the Wilson drums I've got up front.
looks as though a 3/4 inch spacer would work along with longer Mororso studs to get me the clearance.
Never used spacers and theres a lot of different opinions out there
Anyone got experience or opinions here?
Thanks

 

I used spacers/adapters on the rear of my 4 door 32 sedan with no problems. HRP

 

Had to use 1/2 inch billet spacers & longer screw in studs on the Wilwood Brakes to clear the SoCal drums . The 15 x 4 inch rims clear the finned aluminium drum by 1/16 of an inch!

If you use a good quality billet spacer with holes that fit the studs you will be just fine, do not use the old Mr Gaskets with the big alongated slots. Also if you need a bunch of spacer you can look into billet adapters but I think the thinnest you can go there is like an inch and a quarter.
