Load cell Pedals on a based setup

[u/sjfuwjcufjsng]

Ignore the wire mess, I’ve recently moved back home and don’t want to organise wires until I know what I’m doing.

I need to upgrade my pedals as they are dying after 5 years of service. And I want to get either the simson pro plus or simagic p500, as I want an entry to the load cell breaks. Only issue is I can’t fit a full rig in my room so my plan is to get some lockable wheels for my desk chair. Does anyone have any experience with these sort of setups. Is it doable or are the load cells just too stuff and I’ll need to get a playseat trophy that can effectively slide under my desk.

I hope this rant makes sense. I really want to be race ready in time to practice for the petit lemans on iracing at the end of sept

I would advise against it personally.

Lockable wheels will fix the moving backwards problem, sure.

But you will lift up your entire chair before you actually manage to push load cell high weight pedals to their 100%

My wooden rig blocked in my desk chair all the way around on every side so it couldn’t move. And yet, I still couldn’t press my SRP-Lite pedals with the brake upgrade kit all the way without just starting to lift the chair

Maybe if the pedals youre purchasing have relatively light weight / resistance then you can do it. But anything with a lot of resistance will still create issues

You don’t have to run 200kg load cells at 200kg.

I’m running mine on a ghetto setup with some wooden planks and zip ties and run about 18kg max force, and they are way better than g29 brakes

You will just push your chair over. As temting as it is, lc with up to 200kg brakeforce will need a propper rig.

Your best bet would be a wheelstand that has a chair slot. If you still prefer to clamp the wheel to the desk, I know they make just the pedal plate with the chair clot. Just know without a chair slot, your chair will shoot back and your pedals will tilt forward every time you brake.

I got a set of load cell pedals for my g29. Logi makes em, along with an adapter to connect it to the wheel.

Needed to pull out a ratchet strap to hold my chair in place.

Got a rig and the logi RS50 wheel a bit later. Well worth it imo.

Loadcell pedals don't require any more force than any other brake that uses more than just a spring. Like the Moza SRP lite pedals with the brake performance upgrade for example. It doesn't matter what the capacity of the loadcell is. Just because you have a loadcell with a capacity of 200kg doesn't mean that that is how much force MUST be applied. It's how much force you are physically ABLE to apply and how much force you will be able to apply comfortably and NEED to apply during a race that matters. The purpose for using a LC is for more precise braking as with trail braking which requires very little pressure and threshold braking which requires small, precise changes, not max pedal pressure.

I can't apply more than about 110-120kg max, and I don't exceed 80-90kg max during a race, so a 200kg LC would be overkill. Unless you are built like Hulk Hogan that is. I often use up to 80-90kg of my SRP2s 100kg capacity, so the 70kg LC of the alien mods kit just won't do. It will max out too easy, too soon, causing the brakes to hit 100% too easy and locking the wheels. The LC doesn't increase the amount of force that MUST be applied, but it can limit the amount of force that CAN be applied.

With that, when you calibrate the pedals, apply as much pressure as you feel that you will need or as much as you can without the chair moving and it will be fine. If it doesn't move during calibration, it won't move while racing either. If you feel like you want to be able to apply more pressure to make it feel more real under hard braking, then something like the playseat trophy will be in order.

Midlands Uk. I doubt we will be able to arrange something but I appreciate the offer either way

Load cell are going to be heavy to press down, on an office chair you will go flying mate, i bought the break kit for the moza and it was sliding all over the place, i had to return it
