XB4 C Block

We offer several C Block options to fine-tune the performance, steering response, and nimbleness of your XB4.

+2° Toe C Block (Standard Option)

The +2° Toe C Block provides access to both 1° and 0° toe settings, along with multiple pivot-width configurations to precisely tailor rear-end feel. Increasing pivot width trades some corner grip for faster steering response and a flatter, more stable rear end.

This makes it an excellent choice for Stock-class drivers and medium- to high-grip artificial surfaces, where consistency and corner speed are critical.

Pairs with the stock Wide D Block.

+2 HRC +2° Toe C Block

The ultimate choice for corner speed and aggressiveness. This block delivers an extremely fast-reacting car with near-limitless steering both on and off power. Designed for medium- to high-grip tracks, this setup is not for the faint of heart and rewards confident, precise driving.

Pairs with the Hot Lap Designs +2 HRC D Block.

+2 HRC C Block

A more controlled version of the wider HRC option. The +2 HRC C Block retains the nimble, responsive feel while adding increased stability and reduced overall steering for a more secure rear-end that promotes grip without sacrificing responsiveness.

Pairs with the Hot Lap Designs +2 HRC D Block in either Standard or 1° Toe configurations.

All C Blocks are precision-machined from US-sourced 7075-T6 aluminum for maximum strength and durability, making them a premium performance upgrade for any XB4.
