Thanks a lot! Great pictures!I’ve been trying autocrossing with Sumitomo HTR ZIII with zero success; the car was gliding on Marina tarmac as on ice. Star Specs did way better job for me last year. However, one of fastest C class drivers was driving similar car on HTR ZIIIs with no issues. I assume it depends from your driving skill and style. Sumitomo HTR ZIII does not like to be pushed IMHO; Star Specs are holding up much better but might overheat and start losing traction progressively after few runs on heavy car. Sumitomo would be more comfortable for daily driving than Star Specs (it depends from car suspension setup as well). However, I would recommend Star Specs or similar extreme performance summer tires for autocrossing at first glance; they are targeting weekend motorsport activities by design and would give you advantage over more civilized tires.

Please keep in mind that you are driving a heavy car (E93 convertible with a hard roof) with a stock suspension and front weight transfers during harsh breaking overloads stock tires easily. As result, tires are overheating and starting to lose traction. Stock camber plays significant role to the tire wearing out from outside; you cannot do much without camber plates there.For the beginning, I would recommend getting a simple air compressor and tire pressure gauge (with a quick air bleed valve preferably), put extra air to the tires (I would start with 40 psi) before the runs and monitor tire pressure after every run. Tire chalking would give you preliminary idea if the pressure is enough but I would not use it as final tool since combination of car weight and stock suspension would enforce front tire sidewall rollover eventually. Check the tire pressure after every run; you should try to keep the pressure on the same level. Otherwise your tires would overheat and start loosing traction. You would probably need to bleed air out of the tires after first few runs until pressure stabilizes (it depends from tire model and initial pressure in the tire).
I was trying to sell E46 convertibles idea to Jack last year. I assume one of us should win TDS to make it happen 🙂
Regarding E36 t-shirt: great one and would like to get L size! If you could make a limited run with a Boston Green car, I would get it too!
