See, I have a set of PSS springs here - they said (back in the E46 days) the rates between the PSS/10 were the same. Now I don't think that's the same between a M and non M (IE a M3's PSS spring rates aren't going to be the same as a 330i's PSS10)
I wonder what the spring rate differences are between them? Anyhow while I was writing this, I found what I was looking for: https://f87.bimmerpost.com/forums/sh...8&postcount=14 PSS10 M2 are supposedly 514F/800R Progressive? I have PSS with Linear 350F/900/R for flat ride frequency. I'll have less power and tire, and likely less total grip - and less race pace. How far off is all of this worth?

From a road and track feel I'm in love with the 295 square setup. I did upgrade the front sway and it really fits my driving style. It also helped with weight transition in corners.

I'm liking 295 on a 10.5in rim (albeit I'm running a 35 sidewall). Turn in is very sharp and I've got a lot of steering feeedback. Still, I do wonder if it would be even better on a 11in wheel which is hard to fit in front on any F8X.

I do get on the sidewalk more than I'd like. Even with significant front camber. I assume it's my suspension giving up and car rolling over. Would a wider wheel also help with this? I don't think I could go 11" wide at the moment. Maybe with an aftermarket suspension. Having an adjustable LCA helps. Increasing ride height a little, and playing with spacers, etc

Great conversation and I appreciate everyone’s feedback. Sounds like a 10.5” square will be doable given my camber settings with a larger spacer, and running a 275/35 tire on the wider rim should continue to enhance traction and feel.
Sounds like the 295/30 tire will potentially result in slower time as that tire would be better fitted on an 11” wheel. A 285/35 may be a good compromise on 10.5” wheels. I switched to Toyo RRs (275/35), and would like to try the R7 Hoosiers next. Both of them come in the 275 and 285 sizes. |
