The E-Spec frame set and the E-Spec 'PLUS' frame set are guaranteed rock solid with no flexing what so ever. This is an essential upgrade for aluminium cars, hard raced cars, 300+ BHP  motors, racing suspension and brake upgrades.

We strongly recommend additional reinforcement of all the frame mounting points on the front bulkhead including sill front end panels, longitudinal floor members and torsion bar reaction plate.

Weight is increased slightly but this is more than offset by the increase in strength and rigidity - approx 50% up on the standard factory items!

All of our frames can be further upgraded with non-FIA approved upgrades including 'x brace' on picture frame, front frame lower cross member and many more additions to further strengthen specific areas of the sub frames.
