My Weekend At The USCA And Optima Search For The Ultimate Street Car

by Nick Betz

What's the best way to get out of organizing a brand new shop over the weekend? Well, here at MotoIQ the only excuse you can use that won't get you fired is "I'm headed to the track." That was my excuse to not put in a 4th day of shop moving, and it worked! 

Project E36 M3 (Silver): Part 4 – Updating the Interior with Ultrasuede Accents

by Billy Johnson

We spruce up the interior of our beloved 15 year old M3 by having our friends at Coby Wheel wrap the worn and faded steering wheel, arm rest, shift boot, and e-brake boot in Ultrasuede and add Motorsport tri-color stitching to bring out a more modern and sporty character while improving the feel and ambiance of the interior.

Project E36 M3 (Silver): Part 3 - Uncorking the M3 with the help of a Borla Cat-Back Sport Exhaust.

by Billy Johnson

E36 M3s are notoriously difficult to make power out of while staying naturally aspirated and we are constantly in search of the best bang for your buck since a lot of money can be spent for little to no gains in power.

While this E36 M3 was previously used to test various intake components and eventually cams, the quiet 15 year old stock exhaust was left untouched.  With help from our friends at Borla, we dive into the exhaust half of the equation to free up some more ponies without breaking the bank while making our car sound more like an M3 should to better reflect its performance.

Project #YAE92 M3: Part 3 – It’s The Little Things

by Mike Bonanni

If you haven’t noticed, things are moving quickly with us and the Yost Autosport Project #YAE92 M3 endurance race car build! It seems like yesterday this car was sitting on a set of rollers with everything removed but the engine yet in this part of our build journal it actually looks like a race car! Over the past few weeks our lives have been absolutely consumed by this project as the racing season bears down upon us. If you’ve never built a full blown race car before let me tell you this, there are a lot of small things that need to be done that are seldom on the front of your mind.

Project E90 M3: Part 2 - Macht Schnell Bypass Track Pipes and EAS 80mm Exhaust Tips

by Billy Johnson

We continue our difficult quest to extract more power from our S65 V8 without hurting the daily drivability of the car. Since cat-back exhausts don’t really make any power for the E9X M3 and since there really aren’t any aftermarket headers on the market because the equal-length factory headers are that good, the only real performance gain is in the removal of the stock cats. We test the Macht Schnell “Bypass Track Pipes” (Test Pipes) and European Auto Source 80mm exhaust tips to give our stock mufflers a sportier appearance to match the improved performance and sound that the Bypass Track Pipes should deliver.

Project E90 M3: Part 1 - ESS Tuning’s E-Flash ECU & Performance DCT Software

Unfortunately, when a motor is as well-engineered from the factory as the S65 in our E90 M3, it leaves little for the aftermarket to improve upon without spending big bucks building the motor or going forced induction. However, ESS Tuning has years of experience with BMWs and provided us with their E-Flash ECU Software as well as their Performance DCT Transmission software to squeeze out even more performance from an already highly-strung motor.

Project E36 M3: Part 4 - APEX Arc-8 Wheels and Michelin PSAS3 Tires

by Jonathan Lawson

I remember the first time I strolled onto a BMW lot back in the mid-90s to see the new E36 M3 in person. I fell in love with everything about it, including some of the factory wheel offerings. The wheels were considered large at the time, with 17" diameters, and no one knew that APEX would have their 18" x 9" Arc-8s within wheel wells. The M3s were also delivered from the factory with the then-impressive Michelin Pilot MXX3 tires, with no one ever thinking that the "all-season" Pilot Sport A/S 3 would not only perform even better, but allow you to drive in all but the most foul of winter weather conditions.

Project E46 M3: Part 6 - We install the AEM Infinity Engine Management System!

by Pablo Mazlumian

At the heart of any engine is the engine management system.  We install AEM's latest and greatest and are blown away not only by the performance, but by all of the features that transform this car into so much more!

We test a wheel and tire package with eye opening results!  The M3 is now quicker, handles better, stops on a dime, and also turns more heads.  Check out our numbers!
