How To: Schroth Rallye 3 ASM Install MKIV GTI
« on: June 20, 2005, 04:12:23 PM »
First:  This applies specifically to a MKIV GTI (2002), with reclining seats.  I don't know if it is the same for 4-door MKIVs.  I don't know if this is the right place for this...if not, MODS please move it.

Second:  If you don't know what you are doing, or are not comfortable with some of the steps here, don't do it...get someone to help (I'm always willing).  It won't be my fault if you mess up your car or harness.  These instructions are specific to the Schroth Rallye 3 ASM harness...they may work for others, the may not (I know that they will NOT work for the TopSpin harness).

After receiving the harness, I searched for installation instructions specific to MKIVs with reclining seats.  I found a lot of text based instructions, but nothing with photos.  Nor could I find anything that had photos of the actual mounting points for the lap belt.  I did this on the passenger's side, but the same would apply to the driver's side.  The Schroth ASM harness has an expansion clip (?) that helps prevent submarining during a front end collision.  According to Schroth's website, the plastic clip is supposed to be mounted on the inboard side of the seat.  All the bends in the harness mounts were done in order to move the harness up and away from the mounting point (I'm not sure how else to explain this).  Please take a few minutes before starting this to plan the bends you are going to need to make and where.  A little pre-planning will save a lot of post-install aggravaiton.

So, here are the steps that I went through:

Step 1:  Remove the seat.  Use a Bentley's for detailed instructions.  In short, move the seat all the way forward.  Use a box cutter or other sharp object to remove the two, small, round screw covers in the plastic seat track covers.  Remove the screws (phillips) and the plastic.  Push the seat all the way back.  Using a 15mm socket, remove the two nuts at the front-center of the seat (underneath).  Then use a pair of pliers to squeeze the center retaining clip while pushing back on the seat.  Tilt the seat back and remove the plugs for airbag, warmth, and seatbelt as necessary.  Pull the seat out.

Step 2:  I started by installing the rear mount.  I used the center seatbelt mounting point and bolt.  I had to bend the Schroth mounting bracket to fit, as shown in Figures 1 and 2.  I don't have the rear seats in currently, so I'm not sure how this will impact the use of the rear seatbelts.

 

Figure 1:  Rear mount photo 1

 

Figure 2:  Rear mount photo 2

Step 3:  I then shaped the harness mounts for installation.  Figure 3 is the shape I gave to the inboard seat mount; Figure 4 is the shape for the outboard mount.

 

Figure 3:  Inboard mount shape photo

 

Figure 4:  Outboard mount shape photo

Step 4:  I then mounted the inboard mount using the bolt directly beneath where the seatbelt mounts to the track (the oval shaped thing), as seen in Figure 5.  I'm not sure what size the star driver (?) is, but it might be in the Bentley's.  Figure 6 shows the securing of the inboard harness mount.

 

Figure 5:  Slider bolts

 

Figure 6:  Securing the inboard mount

Step 5:  Since the harness is one contiguous piece, I had to place the seat in the car before securing the outboard mount.  Figure 7 shows the seat in the car, and the belt laid out (and it's across the seat) in the way that it will be once the seat is upright.  This is the time to ensure that there are no twists in the belt.  If you don't make sure the belt is laid out right, you will be undoing everything to reinstall it properly.  Figure 8 shows the outboard mount ready for installation.  I cut the area over the bolt before starting any of the other steps, but this can also be done at this point.  Figure 9 shows the detail of the cut out carpet and pad.

 

Figure 7:  Seat in, preparing for outboard installation

 

Figure 8:  Outboard mount pre-installation

 

Figure 9:  Outboard mounting location detail

Step 6:  Using a 17mm socket, remove the bolt, add the harness mount, and rescure the bolt.  Figure 10 shows the harness mount installed.

 

Figure 10:  Outboard harness mount installed

Step 7:  Reinstall the seat, including the plastic slider covers.  I had to modify the outboard plastic cover to fit around the harness mount.  I used a small file (Figure 11) to file out a slot.  Figure 12 shows the plastic mounted with the slot around the harness mount.

 

Figure 11:  Modifying the slide rail cover

 

Figure 12:  Slider rail cover installed

Step 8:  Adjust and fit harness...strap the passenger in...prepare for the screaming.  Figure 13 shows how the harness fits once installed.

 

Figure 13:  Every time I get on the gas I hear this loud screeching from the passenger's side :laugh:

So there it is.  If I need to clarify something, or if you have any questions, please don't hesitate to contact me.

I hope someone finds this useful.

No wonder, looks like she's on a roller-coaster with her hands in the air. Woooooo.... ;)

I was looking at doing the Schroth Rallye 4-Quick Fit harnesses. I'd like to take a look at your set-up sometime soon. Looks very nice, and I have no doubt they keep you planted.

Thanks for the write-up!

You're more than welcome to come take a look...or a ride...or a drive.  I have the Schroth on the passenger's side, and a TopSpin (thanks Randy!) on the driver's side.  The TopSpin was significantly more work to install because of the mounting plates it uses.

Ditto.  This is most likely my next mod.

I have always had this one question...how do insurance companies react to harnesses? I know they should be safer than a typical 3 point seatbelt, but is there any chance they wont payout in the event of an accident (if there is injury) because of a harness? Just a curiosity, otherwise that install looks great and the write up is even better!

I'm not sure.  I do know that the Schroth is one of the few (if not the only) to have a DOT rating.  I should have put a disclaimer that these are for track use only.  I've set them up so that I can still use the stock belts without interference.  I agree with you though, I feel much safer when wearing my harness now than when I'm wearing the stock belt.  My biggest concern would be getting out of the harness (or having someone try to get me out) in case of a severe accident.

I'll give my agent a call and see what he says...

I think the primary argument against 4/5/6-point harnesses in street cars is not just that you'd be harder to get out but that in case of a roll-over, your upper-body would have no place to go. I believe that many racing requirements for 4+ pt harnesses require the use of a roll cage.

You are now the MASTER of racing harness installs!

I agree the Top-Spin is a PITA for your car, but how do the two compare in terms of fit and feel.

I still have one top-spin available if someone wants it.

You know, I haven't even put the Schroth on :wink: I just made Megan do it after the install so I could get some pics.  My mom took a couple of autocross laps with me this weekend and said it felt good, really well planted.  I'll try and let you know.

I just went and tried it out.  While the Schroth does make me feel well planted in the car, it didn't make me feel as secure as the TopSpin does.  Perhaps it's the broader straps on the TopSpin, or the fact that the TopSpin uses the carbon fiber top bracket to keep the shoulder straps square over the top as opposed to pulling to a center point, allowing my upper body to pivot a little.  The shoulder pads on the Schroth are nice, something I may look at for the TopSpin.  All in all, I'd have to give the nod to the TopSpin harness, but the Schroth felt very secure itself.  One thing about the Schroth that the TopSpin does not have is the ASM feature (while referencing the 4-point harness below, it also applies the the 3-point) found here:

 " The patented SCHROTH asmŽ system offers a unique safety advantage for 4-point harnesses. asmŽ is the acronym for anti submarining. The risk of submarining (sliding underneath the lap belt), a well
known phenomenon during frontal impacts, is significantly reduced by the asmŽ safety system. The energy converter is located in the inboard shoulder belt. Therefore make sure you purchase left and/or right harnesses. Severe injuries or death are possible using 4-point harnesses without the SCHROTH asmŽ safety system or an anti-sub strap. SCHROTH harnesses designed for use on public roads (FE models) or those likely to be used as 4-points come with the asmŽ safety system. The performance of the SCHROTH asmŽ safety system has also been tested in conjunction with airbags. However newly developed Head And Neck Supports (HANS) further reduce head deceleration and neck bending. The asmŽ system is not compatible with such devices. Therefore all SCHROTH models likely to be used with such additional devices come without the asmŽ system.SCHROTH recommends the HANS use with a SCHROTH HANS compatible restraint (H-indicated models). Non-asmŽ racing harnesses must always be worn with the anti-sub strap!"

I still would take the TopSpin over this model of Schroth...

Thanks for the info, Ian.  I have only been in a car with Top-Spin belts, so it is good to have a third-part opinion.

Thanks guys...just glad to be of some service.  I actually posted this on the vortex, and while I got some positive feedback, there were still some morons that felt inclined to trash the thread.

If anyone wants to come take a ride, or a drive, to feel the difference in the harnesses, just hit me up.

humm.. those sound pretty good. I have been pondering a topspin, but i may have to swing by and check out the schroth one.

Any time you like.  I work in DTC and live in Lakewood, but I'm always up for a weekend drive.

Nice writeup, Ian.

I had the Schroth Rally 3's in my 84 and 87 Sciroccos and they saved my butt on more than one occasion.  Just being planted better in the seat can make you a better driver.  Less concentration on sliding around.

I really liked them.  Just make sure you have a remote with your head unit so you don't have to loosen them to change the channel or forward to the next song...hehehe...
