AutoBild Magazine: StopTech Big Brakes Are The Best

Posted on February 11, 2015 – 9:00 am

In the December 2014 issue of AutoBild Magazine, the editors rounded up several big brake kits from some of the biggest names in aftermarket braking – Brembo, AP Racing, Performance Friction, K-Sport and StopTech – to compare head-to-head.

As a test subject, the magazine chose a modified BMW M3 that was put through a series of identical tests with each BBK to determine which brake system gave the best overall performance when judged on objective and subjective criteria. The judges looked at braking distances, fade and feel among other things.

As a benchmark, AutoBild used the BMW factory “M” brakes that come stock on the car. Not surprisingly, all of the aftermarket brakes scored much better than the BMW units, except one. The Brembo system finished just behind the BMW brakes, with what the judges felt was a combination of poor performance and poor feel. At the other end of the finishing order, StopTech was named the overall winner, after scoring a perfect 5 out of 5 in every single category!

“No weaknesses came to light during the installation,” according to the editors. “On the contrary – the caliper features a cover that can be opened for the easy removal of brake pads.”

Other areas of praise were the system’s lower weight, shorter stopping distances and fade-free performance – not to mention the lower price compared to the Brembo and PFC systems. You can read the whole English translation of the article here.

Volkswagen (Mk6) Jetta GLI: Brakes, Suspension, & Wheels

Posted on May 13, 2014 – 4:58 pm

Monte brought us his brand new, Volkswagen (Mk6) Jetta GLI in for a few upgrades and personalization.  StopTech’s “SportStop” slotted rotors and semi-metallic “Posi-Quiet” brake pads eliminate the soft pedal feel of the factory brakes while producing less brake dust. An H&R “Sport” spring kit drops the GLI 1.3″ on all 4-corners for that “Euro” stance and better handling thanks to the lower center of gravity.  We wrapped up today’s appointment with the installation of 19″ Hartmann HRS6-204-GA:M wheels after mounting and balancing a set of tires sent to us from Tire Rack.

StopTech ST-41 BBK Install for VW GTI

Posted on December 5, 2013 – 1:56 pm

Xin selected StopTech’s 328x25mm (1-piece rotor) ST-41 Big Brake Kit for his VW GTI, a great way to improve on the stock brake components without breaking the bank. The kits are available for front axle applications and include StopTech 1-piece Sport Rotors, StopTech ST-41 powder-coated four-piston calipers with the patented stiffening bridge, StopTech Street Performance brake pads for extended high performance street driving as well as occasional track use, StopTech braided stainless steel brake lines, plus all necessary brackets and hardware to complete the job.

StopTech One-Piece Big Brake Kits for 2006-2012 VW GTI – Part Number 82.893.5N00.XX

The stiff 2-piece, fully-forged calipers have designated piston sizes specific to this application and provide a firmer, more responsive brake pedal that provides better brake pedal modulation. The larger 328x25mm directionally-vaned 1-piece StopTech Sport Rotors, available in slotted or drilled finishes, provide greater heat capacity and reduced brake fade. Also assisting in fade resistance and higher performance are the StopTech Street Performance Pads which have a high maximum operating temperature and high bite for responsive brakes that can be driven hard. The included StopTech braided stainless steel brake lines reduce system compliance and help provide a firmer pedal with a more immediate and better modulated response to inputs. Available and in stock today at Achtuning, these “entry level” StopTech big brake kits expand our offerings in the high performance aftermarket brake segment, covering not only the Mk5 and Mk6 VW GTI, but also certain EOS, Jetta, Beetle, and Audi A3 applications.

The weight difference between the StopTech ST-41 BBK compared to the GTI’s stock components is also worth noting:


If you are interested in one of these kits for your VW do not hesitate to contact us and schedule an install!

Achtuning and RWB Seattle

Posted on November 15, 2013 – 11:10 am

By now, the Rauh Welt Begriff (RWB) name has spread world-wide and we’d trust most of our followers have at least seen if not heard of an RWB Porsche 911. Akira Nakai of Chiba – suburb of Tokyo, Japan, is the “legend” behind the RWB name and world-wide traveler who creates, shapes, and molds these projects for Porsche owners daring enough to cut up a perfectly good 930, 964, or 993 Porsche 911 and take it to extreme levels.  We’ll spare you the history lesson as you can find a lot about the RWB builds online and immerse yourself in hours of entertainment and information if you haven’t already.  This is what we’re really excited about…

Achtuning has been given the honor and opportunity to play part in the first RWB Seattle build by supplying it’s owner with performance enhancements he’ll need to toss his RWB Porsche, named “Meguri Ai” by Nakai-san himself, around our local tracks! StopTech “Trophy” Big Brake calipers will find themselves behind a set of ridiculously deep-dished Work wheels while H&R RSS coil-overs with complimenting swaybars and Tarett Engineering adjustable end-links will keep things planted while the car is driven to it’s limits. We couldn’t be more excited about this very special, local project and eager to see Meguri Ai’s debut. Stay tuned!!
