I have been looking at different ways to increase the camber beyond the stock component adjustments on my 991.2 GT3 and am leaning towards the Tarett camber plates. I used camber plates with no issues on my E92 M3 so I am assuming it should be no different on a Porsche. I'm hoping some long term owners of the camber plates can chime in here and give their honest opinion of the plates and if they would do something different next time.

Thanks in advance.

It really depends on how much camber you are trying to achieve. It might be easier to add shims to the LCA if it's only a minor increase you are after, but at some point, caster will be out of wack and you'll need to do adjust that somehow (tie rods or caster pucks). Shims also increase front track width.

Camber plates are more expensive than shims, but they don't mess up caster. Don't change track width. Tarret camber plates are totally fine and I would have no concern installing them.

Thanks for the input. I'm currently maxed out at 1.9' with the stock components. I have added 19" wheels with 265/35/19 tires for this season so don't want to change the caster and have rubbing issues. After reading lots of posts on camber requirements at the track I'm assuming I'll want to be around 2.5-2.8'.

Since you are running wider tires and are going past -2.5, I would get camber plates and be done.

Aftermarket inner lower control arms and solid caster pucks are an easy install, easier than camber plates. You'll increase track width going this route and should be able to get the negative camber you need. I've gone this route so I'm speaking from experience.

I’m enjoying these but Hoosiers love camber.

I looked at the Dundon camber plates as an option but it looks like it is a new product and hasn’t proven itself yet.

You can also simply flip your struts L to R and achieve as much camber as you want.

I’d have no issue running the Dundon plates. Call them and chat with them about the development, they spent a lot of time engineering and testing them.

I saw this on one of the posts I’ve searched but didn’t see any definitive answers or end alignment results. Did you swap yours?

I originally added shims and adjustable caster pucks. Easily got -2.7 to -3.0 up front.

When I flipped - got -2.7 to as much as -3.5 no problem (no shims necessary at this point).

You also can't go wrong with camber plates.

Eventually I just upgraded with new struts and springs.

This is only applicable for RS's as they have different top mounts that are offset, rather than centered ones on standard GT3s.

Here's a pic from @Tom@TPC Racing for reference:

OP, the are two methods for camber for 991 GT cars.
1) Offset camber plates to move the top of the strut inward
2) Camber shims on the lower control arms and/or longer lower control arm inners to move the ball joint outward.

Both methods are effective in increasing neg camber angle in itself, to a certain extent. Method 2 will widen front track width and increase neg camber at the same time. The RS cars and Cup cars come factory equipped longer control arm inners and offset camber plates. Having both will give the setup person a larger window of adjustment to achieve target camber and front track width to increase front end grip. I prefer to have 1 and 2 if the situation allows.
