This is how to change the wheel studs to longer ones (not my car on some pictures)

Remove the wheels

Image


Remove the bolts on the backside of the brake caliper (socket 17) and hang it up with a bit of wire.

Image


Remove the center cover on the wheel hub with a flat screwdriver.

Image


Remove the lock pin (replace with a new one)

Image


Use a pair of flat pliers, squeeze the legs together and press out the pin

Image


Remove the centre nut (socket 32). The wheel hub will start rotating, use a long bar or equal between the floor and the wheel studs to hold the wheel hub in place.

Image


When the nut is removed, take out the washer placed behind it and pull off the wheel hub

Image


Press the old studs out. If you dont have a wise or equal, you can hammer them out.

Please try to avoid using to much force when smacking them out, every blow will make small dimples inside the bearings. If you use a small sledge hammer One firm blow is better than multiple smaller ones. Support from behind is good to save the bearings.

Image


Place the new longer studs in correct position (splines). Carefully knock them in a bit. Important that the splines are correctly alligned. Use a larger socket and a wheel nut and tighten till the stud is firmly seated towards the back of the hub..

Image


Clean all surfaces and put new grease on the bearing surfaces. If you plan to use larger brake discs in the future, it is a good idea to remove the splash guard behinf the brake disc before you remount the disc.

Image


Remount the washer, nut and locking pin. Assemble brake disc and spacer.

Image


Remount the brake caliper

Image


Mount the wheels and enjoy the wider stance :D

This is the result on my car (no spacers mounted yet and Camber not adjusted). This is also before the wider fenders are mounted.

Image



I use a 5-stud wheel hub with pin studs. Make life much easier

I do not want to mess around with lots of hard to reach screws and nuts so I looked around to find a good solution.

Thanks to Creatix I managed to lay my hands on a bunch of really good Stainless Steel V-band clamps and flanges. They make life so much easier eliminating the hassle with aligning bolted flanges. Easy to mount and dismantle.

I will use them on the exhaust system, the down pipe, the front pipe, the two wastegates and on the turbon :)

What will happen when the fuel pump in the tank will suck air instead of fuel?

This could happen when you are on the track or during heavy acceleration. The fuel is forced towards the side of the tank, away from the pump. Especially when the tank is not full.
The air will be pumped into the fuel line, onwards to the fuel rail and via the injectors into the engine.

Most of the time this will cause a noticeable decrease of power and it may also damage your engine.

To stop air entering the fuel system, a surge tank / swirl pot is a very good solution.

I have tested a couple of designs and found two really well working versions. Which one to use is mainly a question of available space. Some install it in the boot, others in the engine bay. I will put mine in the engine bay.

If it is installed in the boot, use Teflon hoses. They are more gas tight compared with ordinary steel braided hoses and will prevent the smell of fuel inside the car. They are also resistant against E85.

To connect the hoses to the surge tank / swirl pot, use AN-connections. Usual sizes like AN-6, AN-8 or AN-10.

The installation is fairly simple. Remember the high pressure pump need rather much power and should be connected over a fused relay. It is recommended to use the ordinary pump power feed as relay control signal.
