you can get the 20mm option here in US after delivery...
I have seen the kit for sale on suncoast website.
or you can save some cash and just go for the techart 15mm option.
I think the 20mm option will be 10mm lower than a pasm equipped car right? (since pasm is already 10mm lower)
Best idea is to drive the car for a while and then decide if it looks too high, that is what I did until I opted for the techarts and alot of people still think I havent dropped it...
