Kind of a moot point since my next set is ECF and I fully realize trying to run ECF to cords is an exercise in futility (and heat cycling).

Also good to know about further camber for wider tires. I felt like that was necessary just to fit them under the fenders anyways, but makes sense. I figure with 0 toe up front the extra camber shouldn't kill the insides anyways for street driving.
The Fall Line rear camber shim kit is great for an OEM rear setup.

Just keep in mind that more negative camber = more heat in your tires, so it really depends on your needs and goals. If you need to generate more heat, then running more negative camber is necessary. However, there’s a point where adding more doesn’t necessarily improve performance—going from -3 to -3.5 degrees, for example, might not yield better lap times and could reduce your contact patch, depending on tire size.

Too much camber can also affect braking performance. Excessive camber can still compromise overall grip, making the car slower despite ideal tire temps. It’s all about finding the right balance between mid-corner grip and maintaining stability under braking and acceleration. IMO, it comes down to driving style—some prefer more entry grip at the cost of exit speed, while others prioritize stability on corner exit and sacrifice some initial turn-in response.

Personally, I tend to adjust my camber settings before fine-tuning tire pressures. Camber adjustments give me much faster and more noticeable results, whereas tire pressure changes don’t impact tire temps as drastically. Once I dial in the camber, I’ll fine-tune the pressure to get the most even temps across the tire.

Marking your camber settings on your plates is a good idea if you plan to swap between street and track setups.
