The BMW Mini R53 track project has been around for about a year now, and slowly things have been progressing with it. So it’s about time I did some project posts.
First up was stripping the majority of the interior, fitting bucket seats and fitting an OMP wheel. As you can see from the image above the first things to go were the rear seats and seat belts. Then it was time for the front seats to come out, just removing the seats front and back was a hefty bit of weight saved as they are fairly heavy items.
As you can see nearly everything in the back has been taken out, except the rear panel on the boot and the carpet on the boot floor. The reason the boot carpet is still in, is due to it covering the battery and things still get loaded into the back of the Mini. If you are asking why are there still speakers installed, they will come out once the car is not driven on the road. But for now it is, and doing 200+ miles to a circuit in the thing with no music will drive you mad!
Now to the good stuff, here you can see the OMP sub-frames that were used. These mount into the original fixing points for the factory seats. I would recommend using these over the Sparco ones since they do not raise the seat too much. You can also see the 3.6 ohm fused resistor that was used to stop the airbag warning light coming on. You will need one of these in each airbag SRS plug when you take an airbag out. Next you can see the Sparco slider that was installed on the drivers seat, (passengers is fixed) and the Corbeau seat mounts. Due to how the original seat belts mounted, the mounts had to be drilled and the seat belt clasp bolted to them, I know not the best way to install them, they are only in till harnesses are bought.
Next up we have the Corbeau bucket seats going in. Once the sub-frames were installed and the side mounts, fitting the seats in is quite a straight forward process. To fit the seats to the side mounts, I used the usual allen headed bolt, but also used M8 socket cap aluminium load support washers that the bolts actually sit into.
Last up was the removing of the stock 3-spoke mini steering wheel and replacing it with an OMP 330mm item. To release the stock Mini wheel the process is fairly simple. Follow this guide for the steering wheel removal. Once the airbag is out and disconnected it’s a simple unbolt and you are done. Then its time for the boss, we used an OMP unit, also don’t forget to feed the wires through for the horn and the two plugs from the airbag. You will need to plug two of the resistors into these, the same that where used on the seats to stop the airbag light from illuminating. Once that is done, it’s onto either fitting the wheel or in our case fitting the NRG V2.0 quick release and then the OMP wheel and don’t forget wiring the horn up.
All of the above was done with the battery disconnected, as you should never “play” with airbags that have power going to them. It also means you will not need to reset the airbag light.
There is plenty more still to show and going on with the R53 Track Car, so check back soon for the next update on the build.
