Scrothe Rallye 4pt harness install - Hyundai Performance Forums

Took the time today to finally install my Scrothe Rallye 4pt harness. Purchased it for about $100 if I remember right from some racer supply site I pulled off of the NASA Pro Racing website.

Whats needed for the install:
- harness
- ratchet with 12mm, 14mm, and 17mm sockets and at least 12" worth of extensions to make it easy to get to the bolts
- about an hour worth of time

Ok, first things first, take the harness out of the box and read the install instructions. For the Scrothe harness, you have to mount the front two points on the rear seat bolts and the rear two points on the seat belt mounting points under the rear seat. The Scrothe harness has a special feature that makes it ideal for a street driven car, that is the rear half of the harness is easily separated from the front via a clip. This allows one to detach the harness halves so the rear seat can be used.

Here's the harness itself spread out:

Now for the install:
1) Gather all of the tools and the new harness in one spot. Remove any garbage and loose stuff you have on the backseat. Then, locate the two bolts that hold the seat bottom and remove them using the 12mm socket. On the front of the seat you'll see two clips. Push the clips forward and pull the seat upwards and out of the car. Under the seat, you'll find this:

Take the rear half of the harness to the backseat. On my car, I decided to use the middle seat belt bracket and the driver's side rear seat belt anchors as instructed by the scrothe harness. You can reuse the stock bolts, or use the supplied grade 8 bolts (which I did). The stock bolts are 14mm, the new bolts are 17mm. Also, make sure the scrothe harness is above the stock seat belts when installing (it should go floorpan, stock belts, scrothe harness eyelets).

Now that you have the rear in place, reinstall the rear seat bottom making sure that all of the belts stay above the seat.

Now move back to the front seat. Line up the front half of the harness for where you're going to run it. The shoulder straps go though the legs on the headrest, the waist straps go down to the rear seat bolts. Take the bolts out using the 12mm sockets, line up the new harness eyelets and reinstall the bolts. Now its time to adjust the belts.

If you havent done so already, attach the two halves of the harness together, adjusting the rear harness for adequate slack to fit over your body. Then sit down in the drivers seat and pull up the lap belts. Adjust the belts untill you can buckle it comfortably, then tighten down on the lap belts. Once the lap belts are adjusted, pull down on the shoulder straps adjustments. When you're done adjusting, the lap belt should be snug at your waist and NOT at your belly button. The shoulder belts should be centered on your shoulders and should not be able to slip off.

When you're done, it should all look like this:

Congrats! You now have a racing harness securely mounted and can now concentrate on your driving instead of sliding around on the stock seat.

Sorry, not quite. The shoulder straps have to be +-10deg from the horizontal to be installed properly. You are beyond that.

Also, installingt a harness on a stock car can kill you. You need, at least, a 4pts roll bars. Otherwise, in case of a roll-over, the roof will colapse on you and break your neck. The reason is simple. With regular seat belts, you can fall on the side (your shoulder touching passenger seat) but with a harness, you are stuck in an upright position so you need to make sure that roof won't collapse by installin a 4pts roll bars that will hold the roof up.

A harness is not a bling bling accessory. It is a device to save your life. If something is wrong on it, it will fail and the consequences can be quite serious.

To install a harness the right way....the way it is met to be, you need roll bars. Also, I would not buy cheap or no name brand harness...it is not a place you want to be cheap. Stay with the sparco, momo, omp,...

If it were a 5pt harness, with a submarine belt that would stop you from slouching out of the way, I'd agree. After driving in the car with these belts on I can say that they do not prevent one from slouching down to reach stuff any worse than the stock belts at full lock. Also, the harness is designed around the increased angle associated with mouting in a stock car. Its TUV approved and offered as a factort option for german market BMW's. Scrothe is also a fairly well know company internationally, and supply several DTM and F1 teams, just like the other leading harness providers (namely Williams).

In any event, I wont be using these for daily driving, they'll instead be stowed out of the way untill I'm autocrossing.

Also, if you look in the photo, I'm pretty sure that harness is designed with extra webbing inside of a container. In the event of a rollover, that extra amount is deployed and your body is able to fall towards the middle of the car.

Umm, lol?

Skeird, I know I may sound crazy, but a picture of your car, the inside of your engine, and a subwoofer don't really show us how to install the harness.

:evil:

You should really look into a harness bar and maybe a 5th point if you use it on the street. For autocross I'd duct tape myself in if I had to but if you use that on the street its just unsafe...
