E-Spec uprated side frames to include:

1. Boxing-up of the engine mounting post. 2. Heavier gauge lower frame rail (same physical size as the original.) 3. Extra stiffener tube in the torsion bar reaction bracket (hidden from view.) E-Spec picture frame to include: 1. Extra stiffener around ARB keeper plate mounting (virtually undetectable under normal viewing). 2. Stronger upper and lower cross members and side members (same physical size as originals.) Standard bonnet frame

All of the above are manufactured as a complete set to ensure a perfect fit upon assembly. All of the frames are now uprated as standard including the picture and bonnet frame. The increased rating has been achieved without affecting the crash strength (crumple zone effect) or looks to the originals, the overall effect is to increase tensional rigidity and reduce the bending effect, which gives a firmer stiffer ride with better handling characteristics. The frames are now able to cope with modern upgrades to brakes, suspension and engine power.
