I purchased stock rotors.

Because of the small disc size I didnt want to be too flashy with drilled and slotted. I also do not believe that drilled and slotted is anything more than looks, unless you are on a race track. If you are on a race rack with LT1 brakes....good luck.

This is my setup:


ya, fame brembo's.

I have the LS fronts with LT rears from Brakemotive. Slotted all the way around. Love 'em. Car stops better than I could ask for. The Drilled have a tendency to warp before the blanks or the slotted. It has to do with heating the steel and the way it cools. Personally I run slotted to keep the rotors mostly intact, and it cleans the pads still. FWIW, most of the road course cars I've seen only run slotted. And they abuse their brakes way more than you or I would while on the street.

If you want lt1 brakes stock rotors with good pads will work. However I really recommend the ls1 brake swap. Pull 98-02 spindles off any car and enjoy 8lbs weight savings and awesome brakes.

Drilled and slotted are rotors for ricers. Blanks > slotted > drilled/slotted in braking performance.

blanks are best for braking as said. slotted and drilled rotors give up contact area, therefore not getting as much bite as possible. some quality replacement rotors (stock or ls if you've upgraded) with good pads (hawk hps or hp+) will be more than adequate for anyone short of an instructor's skill level

Over the years, I've had many rotors in many vehicles. Drilled, slotted, drilled and slotted, expensive, cheap, cryogenicly treated, specially coated, you name it.

I even tried an expensive set of Wilwood rotors.

The drilled rotors warped the quickest. Slotted rotors offered no improvement over blanks.

Expensive special rotors warp just as fast as cheap rotors.

For the past two years, I've been using the cheapest blank rotors I can find. They perform just as good as the most expensive rotors on the market.

I spend the money I save on rotors on real performance stuff.

The only way to improve a rotor's performance is to make it bigger and heavier.

Im running brakemotive kit. I love it, stops really well and it looks great behind the wheels.
