About this product

Part #: 127.42100L

StopTech Drilled and Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique cross-drilling and slotting aids with heat and brake dust dispersal, prevents glazing of the pads, adds bite and improves wet and dry braking performance. Built to last, the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation, better crack resistance and increased performance.

What made you choose this particular product?
LMR didnt stock HP+ rears for my car so I just went with these
Is this your first time buying from this brand? Did you consider other brands?
yes, wanted HP+ but LMR didnt have any. Would also consider EBC next time if these arent great
Was it easy to install? Any installation tips that will help others?
yep just flip caliper over and slide new pads in
Once you've had a chance to use the product, did it meet your expectations?

What made you choose this particular product?
Good price and they work very well. Low noise level, good cold performance, and decent feel and bite.
Any additional comments?
Make sure that you bed the brakes properly (Stoptech has a tutorial on their website) for rotor longevity. These pads do make more dust than OEM.

What made you choose this particular product?
Came packaged with my wheels. A bit overkill for the truck imo. I wouldn't buy it brand new for this type of vehicle.
Is this your first time buying from this brand? Did you consider other brands?
Yes, first BBK I've ever bought. I did not consider others at least for this car I didn't.
Was it easy to install? Any installation tips that will help others?
Yes, it was easy once I had all the right parts. I was missing the SS lines at first and the stock SS lines wouldn't fit the caliper properly. I bought porsche brake pads instead of stock stoptech pads.
Once you've had a chance to use the product, did it meet your expectations?
Yes it does. Brake feel is much better than stock.

What made you choose this particular product?
I tried to have my slotted rotors machined, but it was too warped that braking caused severe vibration reverberating through to the brake pedal. Not Good. I needed a cheap replacement ASAP.
Is this your first time buying from this brand? Did you consider other brands?
No. I had the slotted rotors, but I tried to save money by just buying pads. Not a wise choice.
Was it easy to install? Any installation tips that will help others?
If you can turn a bolt, you can install this part.
Once you've had a chance to use the product, did it meet your expectations?
Definitely a good rotor.

What made you choose this particular product?
The performance and the fact that it worked with my vehicle
Is this your first time buying from this brand? Did you consider other brands?
First time buying from this brand. This consider the Motul as well.
Was it easy to install? Any installation tips that will help others?
Very easy. Take old fluid out of reservoir with a turkey baster and then put new fluid in and do the proper fluid flush through the brakes. Helps if you're doing lines at the same time.
Once you've had a chance to use the product, did it meet your expectations?
So far so good.
Any additional comments?
None.
