Brakes

The S1 through to S3 had discs at the front and drums at the rear. S4's and V8S's gained discs at the rear. The braking system is adequete for normal road use, but you might feel the need for improving it for track day or sprinting use, where fade becomes an issue.

Check with Wedge Automotive and Tower View Race Services. Both companies supply and fit improved braking systems for 'S's. Raven Automotive have also established a reputation as brake experts.

Engine

There are a number of companies around that will tune up the V6. I've come across the following in my research, although so far I know little about them:

• Burton Power
• Vulcan Engineering
• Tower View Race Services (They've looked at the Scorpio 2.9 Cosworth engine swap)
• Autosprint (01675 464857)
• Torque Developments (07000 867783)

Exhaust

Wedge Automotive provide new exhaust systems, including stainless steel systems.
