Stim Tech | Rear Strut Tower Reinforcement Boxes

Stim Techs rear strut tower reinforcement boxes are designed to increase strength and rigidity in the rear strut tower area of the E30 uni-body. Tailored perfectly to each of the E30 rear towers and located using the factory rear strut mounting holes and then welded into the chassis. Each box is cut and formed from a single piece of material, which reduces the amount of welding required to fit these and increases the towers’ strength. Upon fitting, the factory strut tower material can either be left in place or cut away behind the welded box. Once in place the boxes are both completely vertical and parallel with the car creating a usable reference point for cage building or other chassis work.

NOTE: Sold as a set of two.

ATTENTION: These reinforcement boxes must be installed by a competent fabricator. All areas where these reinforcements meet the chassis for welding must be prepared properly on both sides prior to welding. It is up to the fabricator/installer to verify that any chassis modifications made meet the regulations of any event rule book the vehicle is subject to.
