if your journey is motorway then the mileage is actually really good as with the type 9 5 speed the 2.8 is barely ticking over cruising
failing that give me the 2.8 and by a mondano
Fast road use
1 Price
2 Effectiveness
3 Ease of Maintenance
I disagree with the comment about the price at the moment, £450+ for a capri LSD axle is a lot of wedge for a lot of people, if your building a big money car then its not a worry, I want to replace the standard axle on my Capri as its been nicked in the past and can't afford to...
You could go for this, designed for the job, its what I'm going to use
