Sorry for jumping in late!
Yes, it's the same height adjustment for SS1 and T0 so you have to lower the car at least a little bit. We recommend about a 25mm drop.
Out on the west coast, Will L. crushes it in 86 Challenge time attack with T0 coilovers (2024 Touring class championship winner). He's a very good driver.
He was on off the shelf springs last year and just switched to 7k/7k.
He runs the Pedders mounts too. Nothing too fancy.

They're very good on track. I do think SS1 ride a smidge better (when adjusted down), but for your uses the T0 is a great fit.
I run my coilovers (a custom KW, but the finish is the same as SS1) year round through salty snow and I don't remember the last time I washed my car. They're holding up great and the Tarmac series with the stainless bodies are even better. You should probably wash your car more than me though.
