Hello,
As many of you start to increase the engine performance of your XLR-V, you might want to consider increasing the braking power. The factory XLR-V brake system uses a two piston front caliper and the rear is a SINGLE piston slider. Now this might be just fine for factory HP XLR-V's...but when you start pushing the envelope you might want to really consider upgrading your brakes. We upgrade the XLR-V's to 6 piston fronts and 4 piston rears!!! Let us know if there are any questions.

Thank you,
