Hi everybody!
I want to share my humble racing seat build and hopefully get some great ideas for improvement.
So I've been a racing wheel user (and a Logitech enthusiast as it turns out lol) for about 15 years (started with the Formula Force GP, then Logitech Momo) and I've had my Logitech G25 since GT5 was released.
Right after the first laps with the G25 I knew that having the steering wheel mounted to a table will just not cut it, so the next day the Ultimate Racing Seat v1 was born:
I built it in a few hours from the material I got from disassembling an old cupboard.
I already had a seat from a BMW E30, so I positioned everything exactly like they would be in a real car and the seat is adjustable ofcourse.
During time and A LOT OF hours, my v1 got many improvements to improve it's strength and also the first mod, which was the Chillicoke's gear shifter mod. The mod was really simple (I just replaced the spring with a longer & stronger one) and made a big difference. So I ended up with what I called the v1.5.
When GT Sport was released, I had to get a Drive Hub to make the wheel work on the PS4. Could not be happier with this - not only was it super-easy to connect, it actually made the wheel function better than it had before (possibly because the PS4 now sees the G25 as G29)
About a month ago I had enough of the ghetto looks of the v1.5 so I bought the material to build the v2:
This time I built everything to be as solid as possible and also did the second mod, which was mounting the G25 pedals vertically. I kept the distance between the pedals roughly the same as it is originally, but the brake pedal is raised a little. This mod is awesome, since the pedals feel a lot sturdier and the feel is so much better. The driving position stayed the same as v1, because it's ideal for me and really gives a feeling of driving a real car.
Before I started building the v2, I had already ordered a bunch of modification parts, which included:
3DRAP steering wheel adapter
3DRAP clutch pedal mod
3DRAP throttle pedal mod
3DRAP brake pedal mod for console
3DRAP mod cambio step 1 H-Shifter v2 + carbon fibre replacement part
Zalem.es 320mm aluminum shifter paddles
Momo-style 330mm steering wheel from Aliexpress
When everything had arrived, it was time for the v2.5:
I really like the 3D-printed steering wheel adapter. It looks great and feels strong. However it's meant for 4mm bolts, but the standard steering wheels use 5mm bolts, so when I attached the steering wheel with the supplied 4mm bolts, there was a little play due to smaller bolt head size. I made one hole of the adapter big enough to fit a 5mm bolt that came with the steering wheel and that did the trick. Over time I might replace all other bolts to 5mm as well.
The 320mm shifter paddles are great, cut from solid piece of aluminum and the perfect size for my 330mm wheel.
Here's a picture of the adapter and the paddles attached.
The pedal mods for the clutch and the throttle are fine, they made both of the pedals a bit harder and are definitely an improvement.
However I am totally amazed with the brake mod, which is a little soft thingy that you're supposed to screw inside the spring of the brake pedal. I don't know how, but this makes the brake pedal function just like in a real car i.e. you don't have to press it against the floor and it will feel hard. One of the best mods so far!
The 330mm steering wheel is a LOT bigger than the original G25 wheel, so it will take some getting used to. However I don't think the original G25 force feedback is strong enough for the bigger wheel (which is actually lighter in weight compared to the original), at least on the PS4 and GT Sport where you can't adjust much.
I tried the shifter mod (it is very easy to install/uninstall), but I didn't like it at all: The shifter would not center itself, I could not get into 1st or 3rd and also had problems going into reverse. I might look into it and try to trim the parts so they would work and feel better, but at the moment the Chillicoke's mod is just fine for me (after all I'm using the paddle shifter about 80% of the time).
So that is how my Ultimate Racing Seat (URS) v2.5 sits at the moment.
I've created some sketches of my plan to build a custom handbrake for it, but other than that I'm mainly looking for ideas on improving the strength of the steering wheel (both structuar and force feedback wise), but I really don't have any.
I've found these videos on Youtube:
But none of them give any information about the build. I'd like to have specific details on what parts to buy and how to build it together.
I believe upgrading to bigger motors and belt drive will make a huge different, but although I've been learning and working in IT for many years, I don't really know what's inside my steering wheel and how it works, so I don't think I would be able to do such an upgrade just on my own knowledge.
I also know about the Ricmotech load-cell mod for the brake pedal, but I'm not looking into it at the moment, because I think that the 10x cheaper 3DRAP brake mod is currently good enough for me.
Also, I know that I could just get the Fanatec components, but that is not my goal - my aim is to improve the G25 set a lot further and only when it should die beyond repair, will I think of upgrading to Fanatec.
So if you have any ideas on other modifications or can give me any information about the builds seen on these Youtube videos, I'd greatly appreciate it!
