It seems like only yesterday but it was actually 20 years ago in 1996 that the Nitto 555 was first launched. Aimed at the center of the growing, red hot sport compact market, the 555 was the new kid in town, the performance leader of a new tire company that burst upon the scene right as it exploded into the mainstream. As Nitto's flagship tire, the 555 was a summer ultra high performance or UHP tire that offered excellent all around grip with good wear to boot.
In this latest installment of Project E39 M5 we will be outfitting our M5 with a set of KW V3 coilovers. We will not only be giving you our usual evaluation, but will also be spending some time explaining our basic theory of basic shock adjustments. It's no secret the grand majority of the MotoIQ staff are huge proponents of KW Suspension's products. Either from personal experience in their own cars or from simply test driving one of our KW equipped project cars. I fell in the latter category.

After ensuring we could stop our newly acquired fun-machine in a previous installment of Project BMW E39 M5, it was now time to let some ponies loose! Our goal; produce more power while maintaining the “quite refined” feel of our performance sedan. It’s no secret the S62 power plant in the BMW E39 M5 was extremely muffled and restricted from the factory. With a price tag rivaling a large down payment on a house, those who could afford a new E39 M5 back in the day were more interested in impressing their power lunch buddies with the M badge rather than with the rumbling performance notes the S62 could belt out. So in the name of sales numbers BMW, like any other manufacturer, put a muzzle on the ol’ girl leaving the performance enthusiast longing for more. But seriously though, what’s the point of having a 400hp engine if you can’t hear and enjoy it?!
With almost 400 horsepower and weighing in at a little over two tons, slowing down the BMW E39 M5 safely and consistently is definitely no easy task. Aside from ensuring all stock braking components are in tip top shape before we start on the inevitable road of power and handling mods, we will also be making a few improvements to the already well engineered braking system of our new/used Bavarian fun machine.
