Great shots of the install.
Thanks to Bruce at Unibrace for working with me on the fitment of the UB to my 2012 4Dr GTI. There must have been some small changes to the underbody tunnel brace stud mounting points over the production cycle that necessitated fine tuning the UB to fit nicely onto my '12. I believe that Bruce had mentioned during our conversation that he had sold many of these to Mk6 Golf/GTI owners over the years and there were no fitment issues, so maybe any changes were only applicable for '12 and forward cars.
The install is really simple and will take no more than 30mins. Only hand tools are required (no power tools) and remember that you are working at your own risk and that all sensible safety procedures should be followed anytime you are working under your car.
1) Lift you car so that you have access to the underside. You can probably install this with the car at an angle like putting the front or rear wheels on ramps. But I felt that I wanted the car to be level just so that I can feel better about the install.
2) Here are images of the factory braces, the front brace is shown in the first pic and both front and rear braces are shown in the second pic. Notice how small and weak the stock factory braces are, they are nothing more than stamped thin sheetmetal. Each brace is held on to the car by 4 14mm nuts with a fixed flared washer on the end. Using the proper sized socket, remove the 8 nuts and remove both braces (You might want to mark the braces and the direction they fit with a marker so that you can re-install it in the future should the need arise).
3) Here is how the UB looks like, its is truly a beautifully built piece and holding it in your hand you can feel how substantial it is and its surprisingly light for such a well built and large piece.
4) On each side of the 'center tunnel' there is a black plastic shroud that runs almost the length of the underside of the car. These shrouds are held on by 10mm plastic nuts. I chose to loosen the shroud on one side since it facilitated the UB in getting in place. The slighly overall wider profile of the UB will require some finessing to get it fitted between the actual floorpan and the plastic shrouds.
5) Once the UB is in place, re-install the 8 nuts that you had previously removed. Make sure that the flared washer end of each nut is fitted into the countersunk cutout of the UB, you should be able to jiggle the UB back and forth, or left to right to get all the 8 flared washer nuts to properly fit.
There were some instructions around that I had read that recommended blue loctite but I did not use any since the threaded studs coming out from the floorpan is painted and I don't think loctite is going to work on painted threads. I also notice that when initially removing the nuts that these are not high torque nuts and somewhere the figure of 25 ft lbs came to mind, but I chose to hand tighten by feel for fear of shearing off one of the studs.
6) All done...I hope to update the thread after a week or so of driving to see what the effects are of the UB by itself. I have the XB as well and will install that next

After one week of regualr daily driving on my normal schedule, here are my thoughts:
1) is there a difference?...yes
2) is there an improvement?...yes
3) is it worth the expense?...yes
The very first thing that I noticed after installing the UB is that there is a subtle lack of vibration under my butt...so you can surmise that I am feeling less vibration coming through the seat bottoms. I actually had to get out of the car and look under to make sure where the UB position was actually at, and sure enough, it was right below the front seat area. Less vibration coming through the seat bottom tells me that things are being held together better or the vibration is being channeled somewhere else...
The very next thing I noticed is that the rear wheels/suspension seems to be further back, away from me...Is this due to the damping of the UB being in the postion that it is?...I don't know...but the rear of the car feels further away towards the rear.
Finally, I noticed that the squeaks that comes from the rear door frames have now changed and the squeaks are coming more from the B pillar and up higher where the window frames are. SO this tells me that there muct be less flex towards at the bottom half of the car, and the flex points are being transferred away from there.
Overall stiffness has not changed and you won't feel the car being stiffer or flexes less when entering a angled driveway...the single most important thing to remember about the Ub is that it appears to be taming the small underlying road undulations...the small vibrations that occur due to surface imperfections are the ones being taken care of. Not the large flex issues...which I am sure is what the XB is made for.
So there you go, take it for what its worth. But as far as I am concerned, price for the UB and the ease of install with noticeable vibration improvements is a win in my books. I am very happy with it.
Don't know if anyone's interested, but there's a group buy on for these right now, $100 off or so... http://golfmk6.com/forums/showthread.php?t=36260. I've got one of each coming for my R already. This writeup makes me even more excited since I'll be doing my downpipe and exhaust at the same time as the UB, XB, and DieselGeek skid.
www.kwiklift.com last year, but trying to go to their website now looks like they are no longer there...
The company was located in Broken Arrow Oklahoma.
There are 2 models (5000# and 7000#) and it raises the car about 24inches off the ground on a flat sturdy platform.
