Mugen Honda Civic AT Group.A Parts Catalog

by Administrator 20. February 2013 12:56


Way back Wednesday- we are going to post the entire Mugen AT Civic Group A parts catalog. We think you'll be amazed at the depth of the parts Mugen made available. You could literally build a turn key competitive Group A Civic from this catalog.


Right-click on an image to see it larger.



The Mugen Group A Civic leads the way. The Group A series was hotly contested by Honda and Toyota with Honda typically having the upper hand...



Mugen Group A Civic engine parts. Forged Mugen pistons with special material connecting rods. There were a few iterations of the connecting rods through the years- some beautifully polished. The Mugen oil pan was a work of art! It strengthened the block and added oil capacity and helped eliminate windage resulting a a 5 hp gain all by itself. The Mugen 30/50 cams were very easy on the valvetrain and had a very sophisticated profile to work with the PGM-FI system.



Part 2 of the Mugen Group A Civic engine parts list- smaller diameter pulleys and the adjustable PGM-Fi ECU and controller. The Mugen hard rubber engine mounts were sold for both race and street cars and made a great improvement! Keeping the engine and engine oil cool was very important- anything over 225 degrees oil temp caused the engine to loose HP.....



Because FIA Group A rules state you must use the factory upper exhaust manifold, considerable time was spent developing the secondary to make the most power. Chromoly lightweight flywheel and AP racing clutch.



One of the big advantages Mugen had over the competition in Group A was a wide range of alternative gear ratios and final drives. With this gearing you could always keep the engine in it's fairly narrow power band. The Mugen Limited slip has been a mainstay of all Honda competition cars all the way back to 1973....



Moving on to the Mugen Group A Civic suspension parts. Here's where things get really interesting. Mugen Showa dampers and upper camber plates, and the really trick front reinforced knuckles designed to be used with an adjustable sleeve that gave even greater camber adjustment. All the different front torsion bar diameters made it easy to dial in the handling to suit the track.




Here we have the quick ratio Mugen steering box (RHD) and 21mm front sway bar. The Mugen rear trailing arms were made specifically to help keep the correct suspension geometry. Mugen made three rear springs rates available, However most opted for an even higher rate linear spring.



The Mugen Group A rear axle with adjustable Panhard rod. The Mugen internal sway bars really worked well and we sold quite a few to street and race enthusiasts. Check out those Mugen 15" wheels......!!!!



We have covered how Mugen made the AT Civic go and handle, so how did they make it stop? 4 piston AP calipers and full floating front brake rotors, single master cylinder and rear disc conversion with all the needed brake lines.



Here's the Mugen brake proportioning assembly and yes- the FIA required a hand brake.....



The Mugen Group A fuel system. A custom ATL 90 liter fuel cell with pump and swirl tank. Don't forget the Mugen gauge cluster with 10K tach. And Mugen SW-36 steering wheel to grab onto!



Lastly the Mugen aluminum FIA roll cage.....



Add up all those Mugen parts with a few hundred hours of labor and this will be you!

More Mugen for John Hinrichs' CR-Z!

by jude_z 28. June 2011 16:38

John Hinrichs really likes his Honda CR-Z. Apparently he also really likes Mugen.


For his fourth major Mugen modification on his CR-Z, John opted for a set of Mugen 17x7 GP wheels in Gunmetal. As with his other mods, John worked directly with King Motorsports President and CEO, Scott Zellner. Scott: "The color of the Gunmetal GP's are a perfect compliment to the Black CR-Z." John is equally happy with his purchase, "I love the way these wheels look!" After each upgrade, John usually sends a picture and a note, or stops by to show us the results, as he did recently with after the GP wheels were installed.


John's other Mugen mods are the Mugen 5-Way Sport Suspension, Mugen Carbon-Fiber Air Intake and Mugen Cat-Back Exhaust.

Customer Feedback: Mugen 5-Way Adjustable Suspension and Cat-Back Exhaust for CR-Z

by Customer Rides 1. November 2010 15:49

** We just got this note and review from John Hinrichs - Thanks John! **



This afternoon I was able to take my CR-Z out for its first fun drive since I picked it up from KMS.  I've driven 30 minutes home, eaten dinner, made myself comfortable on my couch and there is still a big goofy grin on my face.  As much as i love the car itself, I have to give credit for this persistent smile to the Mugen suspension and exhaust you installed.

The factory suspension on the CR-Z was skewed to the comfort side.  Nice for running up and down the interstate, but when it came to corners the car would roll to the outside before it set into the turn.  With the Mugen system the car just turns in. 

Before I set off, I set all four shocks to 5 (full hard).  On the way to my choice bit of road, an area of backroads just south of Friess Lake, I rode over miles of lumpy concrete highways, chewed up blacktop side roads, and more than a few potholes.  The Mugen suspension let me know exactly what kind of surface I was on, but it was never harsh or abrupt. 

The roads I set out to drive are not the newest.  A patched, narrow, blacktop ring of roads that wind around and over the wooded hills of the area -- including a beautifully tight little switchback (which is a rare thing in southeastern Wisconsin).  The car just devoured it, staying flat and collected throughout.  Even in places where the corners were pieced together and uneven, the tires were held down tight, following the rough pavement without any hint of the skittishness that comes with a tire bouncing over the bumps I knew were there.

After driving the 7 mile loop once in each direction, I pulled over to set the shocks to full soft.  Five minutes later I was driving the loop for a third time just to listen to my car.  The stock exhaust note isn't non-existent, and the Mugen system isn't overly loud (I don't get complaints from the neighbors when I get called out to work at 2am like i do with my CRX), it just dials up the bass a couple notches.  In the last few weeks of commuting it has never been intrusive or droning.  I didn't even have to adjust the volume on the stereo.  But on these roads, full throttle from 4k to 6k RPM, the sound echoing off the trees was incredible.  It makes me want to find a tunnel just to listen.

Oh, and in regular highway driving I'm up 2 MPG since the new exhaust was installed.  Win/win.

Thanks for everything,
John Hinrichs

Mugen CR-Z 5-Way Adjustable Suspension Announcement and Review

by Scott_Z 26. October 2010 18:17

Review and announcement by Scott Zellner, President & CEO of King Motorsports and SCCA Road Racing Champion:


In stock form, Honda's new CR-Z is both under-dampened and softly sprung. This combination really masks the sporting characteristics of the CR-Z. 


The Mugen 5-Way Adjustable Suspension Kit was designed with both street and occasional track use in mind. The result is a more controlled ride with much less lean, dive and squat. Each damper adjustment changes both the compression and rebound calibrations so you can tailor the suspension for any driving environment.



The average ride height reduction is 1” front and rear for an aggressive stance, lower center of gravity, and better aerodynamics. This kit comes pre-assembled which makes installation quick and easy.


This kit is without a doubt the best handling upgrade you can make to your new CR-Z.


King Motorsports is proud to be the sole provider of these Mugen CR-Z suspension kits in North America. They will be in-house and ready to ship the first week of November.
