1. 70Lbs [30kg] lead added to front bumper brackets and R/H frame.

2. Centre of Gravity lowered by reduced upper body weight and ride height by 0.5in.

3. Front wheel castor: 4 degrees, camber: 1 degree negative (Seville castor: 2 degrees, camber: 0 degrees.)

4. Rear track widened by 1.25in through use of spacers and GM 'limo' wheel studs.

5. Rear braking increased by 15% through reduced action of F/R equaliser valve.

6. Front spring rate increased by 30%, partly by re-using existing springs in lowered form to compensate for loss of weight, plus by 'nullifying' bottom coil.

7. Rear spring rate increased by approximately 40% bump, 30% rebound by altering certain leaves.

8. Front damping increased by 60% bump, 80% rebound.

9. Rear damping increased by 80% bump, 50% rebound.

10. Rear anti-roll bar stiffened 130% through use of 'double' bar.

11. 7.0in wide wheels fitted all round (Seville 6.0in).

12. Overall structure stiffened through reduced size of monocoque, addition of double tripod space-frame and bracing to rear-end. Book - Sidetracked
