If you want to 60 foot like a rock star those 20s aren't going to cut it.  We all know if you want to drop those track times you're going to need some big meats out back but the big brakes on modern muscle won't let you rock the 15s needed.   Carlyle Racing has the convertion kit you need.  They include all the suspension parts, brakes, rims and slicks needed.
