DCT LSD F/D - 3.45 or 3.62

[spxxx]

Hi y'all!

I'm in the middle of spec'ing a new diff and wanted to get some feedback from others who have run shorter gears in their DCT M3...

I was initially leaning towards a 3.62 as I'm running taller 275/35 tires right now but I'm worried that it'll be way too short if I move back to 285/30 or 295/30 tires (~4% smaller diameter)... So I'm now thinking that a 3.45 with shorter tires would be ideal.

Anyone have experience with 3.62 gearing and these tire sizes? Ideally with CA track experience (Buttonwillow, Laguna, Thunderhill).

Please do, I think I'd love a 3.62 after driving a 3.45 FD car (thanks spooni ) - it didn't feel much shorter than OEM with 285/30 tires. According to my math a 3.45 is ~9% shorter and running a 285/30 tire is ~4% shorter than a OEM FD with 275/35 tires.

I plan to run 295/30 eventually so I don't want to go too short with a 3.62.

Sorry for the very specific questions, thanks all!

Need help with AP 9668 pad options.

I'm running Ferodo DS1.11 and want something with more initial bite. I love that these don't wear, like at all, but really want something that doesn't require a ton of pedal force to get to stop.
