Ideas in making Fanatec's McLaren GT3 wheel stiffer?

    I'm an incessant tinkerer which goes hand-in-hand in being a little bit OCD. I really like Fanatec's latest wheel - the McLaren GT3. A small niggling thing about it though is because it is plastic there is some flex. In watching SRG's review of the wheel where Barry has it apart, I can see the gusseting employed to help stiffen the unit. I'm wondering if I fill the various pockets with epoxy, if it would noticeably stiffen the wheel without adding much weight or would the results be negligible.

    Wondering if anyone with a structural engineer background or penchant for these things have any opinions/suggestion.

    Here's a screenshot from SRG's review. My thought is to fill the voids with epoxy to add stiffness. I would remove the main board as well and fill voids under it as well.

    I use it on my osw and there is hardly any flex at all.
    I guess it will either hold or break in half but guess its designed for the podium series. Doesnt mean its designed for 20 nm but use it pretty hard and feel no flex at all.

    It may just be the prolongued axis but flex is if any only up and down. But may be my mige.

    Interesting! And good to hear since I'm considering Fanatec's new dd if it is received well.

    You can feel the flex if you twist at the grips in opposite directions. Not a lot mind you but its there. I would also like to get the wheel to feel a bit more solid. During rapid fire ffb - say, going over the rumble strips in kerbs - it just sounds/feels a bit... um... plastic. Hard to describe. When I had their F1 wheel, it just felt solid thru and thru. Again, I realize the GT3 is plastic. I'm just seeing if I can "tighten" it up a bit.

    Ah well never do that twisting motion while racing or using the rim normally but yes I started to hear some plastic cracking noises doing that :)

    As for sound I use headphones but you don´t think it´s the top two lsb and rsb rattlesnake buttons that make the noises? When dry simming with the wheel in the air they did make some noise. Also remove the piece with the bolt adapter or what it is it rattles. I have never heard any sound from the mclaren wheel beside the top buttons once removing that.

    Didn't take me long to get that bolt adapter out! :p

    I was trying to pinpoint the rattle. I will see if it is those two buttons on mine as well.

    Actually, it's not a rattle I have but a squeak during severe ffb. If I can make the wheel more solid, I think it'll take care of it.

    I just run the FFB a little lower than I would with the BMW rim. I am on OSW 20nm. I don't like heavy FFB anyway, so for me it's OK. I do feel a little bit of movement, very very slightly. But with FFB low enough it never bothers me at all. With earbuds in I probably wouldn't even notice it at all.

    Did you try this?! Or are you just teasing me! :D

    Thanks for the pic either way. It is basically exactly as I imagined after watching SRG's video. Basically, my plan is to maybe not completely fill but hit each void with epoxy starting outside working in. I figure I will use up one or two of the plastic epoxy syringes like the one shown in your pic, let it fully cure and try it out.

    As I continue to think thru this - I think it will be a bit of a challenge to do this neat and clean. I would love to be able to mix the epoxy and pour it in but these types of epoxies tend to be pretty thick. I'm wondering if the epoxies used for filling voids in wood for, say, table tops would work. Those are much thinner and are meant to be mixed in a cup then poured into a void. I'm just wondering about the bond. I'm assuming those epoxies formulated for plastic will partially melt the plastic to adhere to it.

    Or am I overthinking this? :geek:
