Product Details
The BLOX Racing Subframe Hard Collar Kit stiffens the subframe and chassis on your 2001-2005 Honda Civic (ES/EM2) by replacing the factory rubber subframe isolators and/or bracing vulnerable chassis points. On a EP3/ES Civic that sees track duty or aggressive driving, every bit of chassis flex costs you precision — these hard collars and braces give the suspension a more rigid platform to work from.
CNC-machined billet aluminum collars (or steel tunnel brace, depending on kit) install inside the subframe voids where the factory rubber isolators sit. The result is a near-solid subframe mount without the NVH of a fully solid bushing — you feel the EP3/ES Civic's true suspension behavior through the seat of your pants, not filtered through worn rubber.
