I'm getting ready to replace the clutch on my car and I'm hoping to do more track days in the near future. Replacing the inner ball joints is on the list of things to do when the front subframe is out, and adding more negative camber up front is also on the list of things to do soon. I was thinking about either IE fixed camber plates, or some adjustable camber plates.

But tonight I started thinking about using the powerflex ball joints to add negative camber. Has anyone tried these? https://www.waymotorworks.com/powerf...0-r52-r53.html

Any downsides like accelerated ball joint wear?

I do anticipate some potential increased inner tire wear, which is part of why the adjustable camber plates are appealing, but I'm willing to live with some decreased tire wear if the handling improvement is worth it.

 

If you are doing track days you are going to want to go with a full on camber plate like the Vorshlag. That way you can adjust the camber and dial it in exactly, plus the Vorshlag are bullet proof so they won't fail.

The PF ball joints will just add some neg camber, but they are not adjustable so you won't be able to get it even, or if your car already has a camber split it will become worse.

I would make sure you do the PF control arm bushings, and steering rack. Then you can also do a bigger front sway bar to get more out of it at the track.

A bigger front sway bar is against all conventional wisdom on a FWD chassis without significant other modifications in combination.

 

Yes it is against "conventional wisdom", but can tell you that when you match it with the bigger bar it is a fantastic improvement. Especially if you are tracking the car and more so if you have an LSD as it will help plant the front to get the power down. I've had a big front and rear bar setup in my race car for years and would never go back. I've built many MINIs with this combo and all love it so you if you haven't tried it you don't know what you are missing.

 

I'm curious about this, because a gear-based LSD will increase understeer at the limit of traction, rapidly exacerbating the heavier front sway bar. If you mean a clutch-type such as an OS Giken, then the LSD would not increase understeer. For road use, preference would of course trump lap times, but that's not usually the consideration when talking COF.
