Project E39 M5: StopTech Front & Rear Trophy Kit Installation

by Martin Gonzales

In our Brake Refresh Article we maximized the capabilities of our E39 M5's OE braking system by using StopTech's Sport Axle Pack, which includes slotted rotors, stainless steel braided brake lines and Sport brake pads. Front brake ducting was also added in order to improve on our project's susceptibility to brake fade. Though these improvements left us with a braking system that performed better than stock, the E39 M5's brake system has a lot of room for improvement. We will turn the knob to 11, with StopTech's Trophy kit!


 

Project E39 M5: K&N Filters and HPS Intake Hoses

by Martin Gonzales

In this installment of Project BMW E39 M5 we will test two very easy to install intake upgrades- the high flow K&N drop-in filters and HPS Performance Parts silicone intake hose kit. We will be doing individual dyno tests for each part to see if they can free up the S62's intake tract and yield some measurable power gains. 


 

Tested: Nitto's new 555 G2 High Performance Tire!

by Mike Kojima

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.


 

Project E39 M5: Part 3 - Installing and Adjusting KW V3s

by Martin Gonzales

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. 


 

Project E39 M5: Part 2 - Installing and Testing the Corsa Performance Exhaust

by Martin Gonzales

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?!


 

Project E39 M5: Part 1 - Stopping the Ultimate Driving Machine

by Martin Gonzales

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.
