Although unassisted steering was retained along with fixed suspension, extensive changes were made to the existing rear drive Diablo, the emphasis being on shedding pounds and increasing performance. . New to the SE30 was a traction control system that enabled drivers to select the most suitable setting for conditions, one-piece OZ Racing magnesium wheels having been of 18-inch diameter at the rear and 17-inches at the front. Perforated brake discs increased stopping capability, overall weight dropping to 1451kg compared to 1576 and 1625kg for the standard Diablo and VT respectively. Despite capacity remaining unchanged at 5707cc, the 30th Anniversary produced 33bhp more than its sisters with 525bhp at 7000rpm. This jump was thanks to a reprogrammed LIE engine management system and free-flow sports exhaust. Compression went unaltered at 10.0:1. Weight of the engine itself was lowered by using magnesium intake manifolds and cylinder heads, all of which contributed to the SE30 posting the fastest performance figures yet for a Diablo - 207mph flat out and 0-60 in four seconds dead. Outside the SE30 also got a number of distinctive features that marked it out as something a little bit special. A more aggressive stance was achieved thanks to those bigger rear wheels, the weight-saving continuing with redesigned carbon fibre skirts, bumpers, front lids and engine covers.

The front bumper with its deep chin spoiler had intake grilles mounted inside the supplementary driving lights and the Lamborghini badge repositioned from the front lid down to in-between the indicators. There were also lightweight two-piece door windows, twin blade engine intakes between the wheels and an external fuel filler. A distinctive slatted engine cover mimicked that of the Miura, other distinguishing features including an all new lightweight rear wing that came fitted as standard. Identifiable by the drooping corners and adjustable Gurney flap, only a handful of SE30's were built without this appendage.

At the back, a new grille was embossed with a chrome logo and 30th Anniversary scripting, a reprofiled bumper capping off the changes. Inside, the air-conditioning and electric windows were junked, leather typically being exchanged for suede alcantara and used on the carbon fibre bucket seats, dash and central console. Four-point harnesses kept occupants firmly in their seats, the drilled aluminium pedals, cockpit-adjustable roll bars, extensive use of carbon fibre and white-backed dials in a VT binnacle all adding to the mix. An automatic fire extinguishing system was plumbed into the engine bay and could be operated via a dash mounted switch, another neat feature having been the unique steering wheel with vintage horn push. Launched during September 1993, the first deliveries weren't actually made until June ¡Ë¢çE¢®Ec?94, the last car rolling out of the factory in November 1995. Although 150 SE30's were built, between 12 and 28 were completed to Jota spec. Weight remained unchanged, the most obvious developments being focused on the engine. This now produced an astounding 595bhp at 7300rpm thanks to reprogrammed LIE management and a straight through competition exhaust. Externally identifiable by the two air scoops located over the engine cover, the Jota was perhaps the most extreme Diablo ever and like the subsequent 6-litre GT, never originally legal for sale in the USA.
