    Nielex Pro-Spec Bushing Kit review/input needed

    Hello fellas! Has anyone here use this Nielex Pro-Spec bushing kit from Rev9? I wonder if they are identical with the ILMotorsport bushing kit that FM sells. The stiffness they are advertising is all about the percentage compared to stock unless I missed it somewhere. Any input would be greatly appreciated.

    Maybe reach out to Maxime at Rev9? He should be able to answer all your questions about this product.

    +1 with checking with Maxime at Rev9Autosport.

    I have the IL Motorsport bushings, they’ve been amazing. Around 30-40% stiffer than stock according to IL. The old stock ones were worn out beyond their lifespan so I don’t have a fair stock/IL comparison. My suspension is a lot more compliant since though...
    You want a good car. I want a good miata.

    IL for the diff is a pain in the butt to install, unless you have proper tool.
    Poly slides in.

    Poly is a literal pain in the butt. It wasn’t that hard. The worst as always is the rusty bits.

    Yeah, Slampen is right. I've installed PU in a number of diffs and it was a lot easier compared to the rubber ones. In static applications, I prefer to use PU. I like rubber in the articulated areas for easy of maintenance and noise (dual-use and street applications). There are ways to improve upon PU control arm bushings; bronze sleeves, adding zerk fittings, teflon tape (haven't used it), but when the bore the PU bushings fit into are contaminated, it's a squeaky, noisy irritation.

    I agree on the static vs. moving thing on PU. I do not like PU on suspension joints as well, mainly due to "stiction". Can be combated as KFJ mentioned, but it is really rare that someone actually gets it and does something about it. SadFab is the only one I know of offering a decent off the shelf solution for PU suspension bushings.
