Koni sport stud sizing for GC camber plates

[E46m3zcp]

Hi all, I'm looking at getting Koni Sport dampers and GC street camber plates and on GC's website I'm given the option between these two. What is the Koni Sport (aka "yellows") sizing?



Aside from that, any comments welcome on my choice to go with Koni Sports + GC on stock springs (and possibly Eibach later on)

My goal is to maintain the car's geometry (roll center) close to stock while leaving a door open for a stiffer spring in the future, and my #1 priority is get more negative camber to stop riding the tire's sidewall during track days.

they are the left one (14 thread, 16 shoulder)

the Konis were discussed at length in the other threads here on the main page

Konis are considered stock replacement struts. You'll need to use the stock "strut spacer" unless GC has some other tapered adapter that I'm not aware of.

Are Bilstein B6's stud also the same? Now that you pointed me in the direction of other posts, which I have read, I am no longer sure if I'll go Koni + OEM or B6 + OEM.
This post really made me think B6+OEM springs could make sense.

This is all pretty confusing at times...

B6 are considered stock replacement also and therefore directly interchangeable with OEM, Koni, etc.

I don't think you're going to notice a huge difference in B6 vs Koni.

Is there any benefit to using camber plates if a car is sitting on stock springs and wheels?

-More alignment flexibility for different handling characteristics
-More bump travel on stock shocks (assuming the spring is shimmed as well)
-It looks cool when you show someone your engine bay and you can see aftermarket bling through the strut towers

I personally run the stock ones but those Turner Hybrids sure look nice.

You will.

Yes,

If you drive the car to its limits your tire wears unevenly without enough negative camber (see my image). That’s completely independent of having a modified suspension or aftermarket wheels. Lowering springs can add negative camber so it might not be as necessary to have camber plates on a car with lowering springs as on one with stock springs.

Check out this explanation here: https://www.tirebuyer.com/education/...egative-camber

In my humble opinion more camber adjustability is the second most important modification after sticky tires for track days.

I will even go further and say that if a lower lap time is your priority you should not lower the car, unless you are ready to do geometry corrections (google roll centre correction). And your wheels should be as small (in diameter, not width) as you can while clearing your calipers. The stock m3 is pretty decent on a track, once you give it a proper square setup to make it neutral and get enough negative camber to not ride your sidewalls.
