I can handle cats, I just think they are stupid unless they are on a farm. Or it's a tiger, tigers and other big dangerous cats are cool. House cats are pointless. You want a good pet get a Komodo dragon. It's just like a cat but better


Back to the topic for the sake of keeping this on track....

I will argue that they don't really muddy out the steering feel, I haven't yet driven a Miata with the modified knuckles but I have driven a s2k with modified knuckles that used the stock steering rack. Didn't feel any different than what it was like before the mod other than it took less movement to turn the same amount.

The reason they are bad is because they aren't all the same and because of that you might end up with something funky where someone else doesn't have that...

Depending on the fixturing of someone that does offer them, you could get some that are wildly different because of warping with welding, etc.

Then there is the weldment itself that can be bad, but you should have a certified welder do these arms with proper post weld heat treating and xray testing and not some joe blow XdrifterX kid... but then your looking at real $ to ensure your safety.

The only one i know who is making knuckles worth mentioning in this thread is Danny George. He got the fixtures from Chelsea Denofa who used to drift miatas. His are probably the best on the market and even then i question them.

Are you trying to achieve more angle or quicker steering?

I have modified knuckles from Danny on my NA Miata. Other than the knuckles being NB knuckles (Danny was out of NA knuckles), which required a change of the upper control arm/ball joint, they work well. I was able to get toe back to around zero with all tie rods screwed in all of the way. I do need to space the rack and/or try out the bump steer elimination kit for V8R, but they dramatically improved the drifting capabilities of the car.

The knuckles from Danny are top notch. Considering Danny George is a professional drifter, he has been very approachable when asked questions about how to setup a Miata to hang with all of the damn Niassns in grassroots level drifting.

BTW... I also have a 99 Miata which I picked up a couple of months ago which will be setup for track type racing and autocross.

Thanks

biggest set back is wishbones, need decent tubular wishbones for lock, then the tie rod end hits the arm with the knuckle shortened too much so you need a rack with massive throw! extended tubular wishbones is the key, gets the wheels away from everything.. that with a bigger steering ratio and a rack with huge throw you'll win at everything... around 5 to 6 deg neg front camber, softer than race spring rates but decent anti roll bars, drop knuckles @ rear to correct camber to -1 deg camber max... not yet got mine running yet but thats a setup id start with. tune the car with dampers, springs and tyre pressures. obv all the normal miata race stuff still applies..

EDIT: the above assumes you want skids, The reason why shortened steering knuckles are bad is because by giving a larger steering ratio they increase bump steer (where before you had close to zero bump steer, you now have more steering movement thus more bump steer) the other reasons why they are bad is because the welding is usually ***** with little to no root penetration and the jigs used are mostly just pure guesswork. Andrew Keisler does knuckles with a larger steering ratio. (that is accurate!) - or atleast can produce them.
