It sounds like tire manufacturers will have to figure out how to make the performance tires compliant for CA and that will be the standard for everyone across the board. I doubt they would make a CA only version?
I had a sirimoto and a 27won strut bar and always torqued down the nuts to 55 ft/lbs no problem. Since you have to replace the strut mount I have a pair of new Whiteline offset strut mounts in the classifieds if you’re interested.

I pulled off my Superpro LCAs late last year due to some clunking from defective bushings. I just went back to OEM LCAs with the Whiteline inserts and I can say that I haven't felt much drop off in terms of performance but NVH is much better. Road impacts aren't as harsh anymore. Would highly...
