Holidays are fast approaching........there should be some descent sales. Shelby America usually has 20% off sale around thanksgiving on there parts if the wilwoods interest you.The prices for rear 4 piston rear brakes is insane. Solid axle makes it more so. They are nice. But six pistons in the front, floating calipers in the rear is more than enough for most applications.. But the 4 pistons are real nice bling. I wish they had a kit to fit my old 4 piston Brembos on the rear.
