PROJECT CARS: Project S4 Track Preparation

Project S4, our old dog leaning new tricks, is getting ready for some track time later this "Summer" (good job it's equipped with Quattro in this weather!). We're just about to go up to our good pal Dave Green's garage at Henstead Motors (http://www.henstead-motorsport.co.uk/) to fit a raft of suspension upgrades and finish off the brake kit fit, in preparation for some track days, end of this season and into Autumn and Winter (we like to slide). First up, we're about to fit the Tarox (http://en.tarox.com/) grooved, heat-treated, hand finished solid rear discs and re-bleed the system to maximum stopping power, fade-free on track as it has been on the road, we hope. Great piece of kit. Then we are setting about optimising the S4's suspension – already upgraded with Bilstein PSS9 coilovers, which are fabulous. We're fitting a full set of Powerflex (http://www.powerflex.co.uk/) high performance Polyurethane suspension bushes, replacing 12-year-old rubber with 30% stiffer, longer lasting polybushes, which should reduce tyre wear, increase braking and cornering stability and reduce inertia no end... not to mention match the Bilsteins in upping the grip level, further still. High hopes for these innovative, great value products. Speaking of grip, we're also fitting an upgraded, heavy duty rear swaybar (anti-roll bar or stabiliser bar to some), along with camber and caster inducing chassis control devices from Australian suspension genius brand, Whiteline (http://www.whiteline.com.au/). Most effective, best value modification you can make to your suspension... just maybe?
