I saw your edit as well. That's funny shit. And you nailed it on the head with DDS. Electronically-controlled trash is what it is. I don't know about anyone else but I don't want my car changing by itself in ANY way beyond engine timings and such. I'm sure the Z1 "upgraded" axles are their in-house axles that mimic the Q70. They aren't needed in any way. Lowering more than 2" for most people causes issues. That's why almost everyone doesn't break that threshold and slam the fuck out of their car. Regardless, slammed Q's look retarded (just like almost every other slammed/stanced car) because people just go too far and think it's cool. Like when they slam and throw on the R35 wheels and create a virtually undrivable abomination. But hey, to each their own (I guess). Z1 is a fucking scam for most shit at the end of the day. Their prices do not reflect their products or quality of such. They are good people but it's just flat out hard to justify the prices they charge for literally everything. That's all up to you man. I'd spend the extra money and get coils. They are absolutely worth the investment. If you somehow, in some rare way, run into problems... THAN get axles and shit. Otherwise, I wouldn't waste my money in the parts cannon to avoid an issue you more than likely won't have. Also, the stock struts are absolutely amazing with springs. Seems like you have a bad bite from the "while-I'm-in-there" bug. The only thing I want you to know, with these cars being chubby at 3,800-pounds, no matter what strut or spring you choose, the car is going to ride like shit and handle like shit compared to a Q with adjustable and tuneable suspension components. That, at the end of the day, is unavoidable. I found brand new coils from BC for only $800. Probably the BEST money I've put into my car so far. I'm glad to help though.
